How to clean out all the earwax buildup in ears from hearing-aids if hearing-impaired? Q-tips are unsafe, right?

<p>I was born with congenital bone fusions in several places in my body, one of those places are in the set of three small bones (malleus, incus, and stapes) in both my ears. Because they are fused, they don't vibrate. I've had several ear surgeries, which have unfortunately only caused nerve-damage and scar-tissue so I'm hearing-impaired. Bottom-line: <strong>I've been wearing hearing-aids my entire life.</strong> </p> <p>Growing up, I would always use a Q-tip to clean out the earwax buildup in my ears <strong>(hearing-aids are constantly in my ears so they don't allow my ears to "breathe" and trap in a lot of bacteria)</strong>. However, as research became more available as the years went by, audiologists and doctors alike have told me that Q-tips are not the best way to clean out your ears. In fact, they have the potential to cause further damage to your ears because you may just be jamming the earwax further down your ear canal, which can lead to infections/inflammations/loss of hearing, etc. </p> <p>So the alternative method to cleaning out my ears with a Q-tip was to blow-dry them when I got out of the shower. I did this for a few years until the audiologists said that even though the blow-dryer doesn't sound too loud to me, I could be causing a lot of damage to my ear drums. </p> <p>I don't recall what the alternative cleaning method has since been. <strong>How do I clean out my ears on a regular/daily basis?</strong> Yes, I am fully aware that a doctor can flush out the earwax, but I don't have the time nor the money to constantly be seeing the doctor since I have earwax everyday due to my hearing aids. I have a lot. </p> <p><strong>What is the safest, most effective, yet realistic/practical method?</strong></p>

In younger children hypothyroidism is most often congenital. So yes, you almost certainly have hypothyroidism due to Hashimoto’s disease.</p>\n\n<p>Hashimoto’s thyroiditis is an <a href=\"https://www.webmd.com/a-to-z-guides/autoimmune-diseases\" rel=\"nofollow noreferrer\">autoimmune disease</a>. This means that <em>something</em> triggers the immune system to produce antibodies that cross-react with normal parts of the body. People with Hashimoto’s disease can have antibodies in the blood to various components of the thyroid gland. The most common are <em>anti-thyroid peroxidase (anti-TPO) antibodies</em>. You may have had a blood test for this and you could certainly ask your family doctor or endocrinologist. Either way, the treatment is similar to other causes; namely replacement of thyroid hormones with <em>levothyroxine</em>.</p>\n\n<p><strong>Autoimmune disease in general</strong></p>\n\n<p>The origins of autoimmune disease seem to be a complex mix of genetic and environmental factors and possibly pathogens. Much autoimmune disease is due to various forms of immune <a href=\"https://en.m.wikipedia.org/wiki/Hypersensitivity\" rel=\"nofollow noreferrer\">hypersensitivity</a>. Specifically, Hashimoto’s thyroiditis is an example of <a href=\"https://en.m.wikipedia.org/wiki/Type_IV_hypersensitivity\" rel=\"nofollow noreferrer\">type 4 hypersensitivity</a> (along with coeliac disease and multiple sclerosis), while <a href=\"https://en.m.wikipedia.org/wiki/Type_I_hypersensitivity\" rel=\"nofollow noreferrer\">type 1</a> causes most allergies and anaphylaxis.</p>\n\n<p>A good example is autoimmune disease after infection by <a href=\"https://en.wikipedia.org/wiki/Group_A_streptococcal_infection\" rel=\"nofollow noreferrer\">Group A streptococcus</a> bacteria (a common cause of throat infections, skin infections, <a href=\"https://en.wikipedia.org/wiki/Scarlet_fever\" rel=\"nofollow noreferrer\">scarlet fever</a> etc). In some people, the antibodies that the body makes against streptococcus will cross-react with other body tissues and damage them, causing a number of conditions: </p>\n\n<ul>\n<li><a href=\"https://en.wikipedia.org/wiki/Rheumatic_fever\" rel=\"nofollow noreferrer\">Rheumatic fever</a> and rheumatic heart disease (<a href=\"https://en.m.wikipedia.org/wiki/Type_II_hypersensitivity\" rel=\"nofollow noreferrer\">type 2 hypersensitivity</a>)</li>\n<li><a href=\"https://en.wikipedia.org/wiki/Acute_proliferative_glomerulonephritis\" rel=\"nofollow noreferrer\">Glomerulonephritis</a> (<a href=\"https://en.m.wikipedia.org/wiki/Type_III_hypersensitivity\" rel=\"nofollow noreferrer\">type 3 hypersensitivity</a>)</li>\n<li><a href=\"https://www.psoriasis.org/about-psoriasis/types/guttate\" rel=\"nofollow noreferrer\">Guttate psoriasis</a></li>\n<li><a href=\"https://en.wikipedia.org/wiki/PANDAS\" rel=\"nofollow noreferrer\">Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS)</a></li>\n</ul>\n\n<p>See <a href=\"https://www.ncbi.nlm.nih.gov/books/NBK333434/\" rel=\"nofollow noreferrer\">this paper</a> for more information about autoimmunity after streptococcal infection.

Having one can make another more likely. For example, there is a link between <a href=\"https://en.wikipedia.org/wiki/Diabetes_mellitus_type_1\" rel=\"nofollow noreferrer\">type 1 diabetes</a> and autoimmune hypothyroidism. You mention that you may have lupus, which is also autoimmune. </p>\n\n<p>You also mention fibromyalgia.

It is likely to result from a complex interplay of internal and external factors with neurochemisty and neurophysiological processes. There is some overlap in symptoms, but this is not surprising as pain, stiffness, fatigue and low energy are some of the most common symptoms there are and can have many causes.</p>\n\n<p>I see from <a href=\"https://health.stackexchange.com/questions/9660/why-do-some-general-practioners-not-consider-fibromyalgia-as-a-genuine-real-aut\">another question</a> of yours that you had a bad experience with a general practitioner taking the very outdated view that fibromyalgia is not a real condition!

Effects of microdosing alcohol on liver performance and the ability to metabolize toxins
[ "alcohol", "liver", "metabolism", "toxins" ]
<p>Has there been any research on microdosing of alcohol? I did a cursory search but it didn't yield any viable information.</p> <p>Putting regular stress on various parts of the human body and its systems seems to have an overall strengthening effect. Working out builds stronger muscle, microdosing poison gets you some immunity to poison, bone microfractures lead to denser and stronger bone and so on, gradually and continuously working out various parts and systems of the body appears to have a beneficial effect on their performance.</p> <p>So what would be the effect of subjecting the organism to continuous alcohol microdosing? And I don't mean "drink a little once a day" but adding a minuscule amount of alcohol to water and other consumed liquids, dosed according to the liver's performance so that the alcohol level doesn't exceed the legal limits you can drive a vehicle with, perhaps even significantly lower than that.</p> <p>If poison microdosing builds up immunity to poison, and I am only assuming that it is being metabolized by the liver and thus improves its ability to metabolize poison, wouldn't alcohol microdosing too make up for a stronger liver?</p> <p>I've also read about studies which show conflicting results, while some appear do indicate there are some benefits to drinking a little alcohol (but not microdosing), others claim that drinking any amount of alcohol is detrimental to the health, but again, that means drinking recreationally, not microdosing.</p> <p>EDIT:</p> <p>Now that the question gets input, it mandates a clarification be made, that I am specifically interested in liver performance and ability to metabolize toxins, in case it wasn't clean enough. And to clarify the need for this clarification:</p> <p>There is a problem with mortality rates, due to the extremely uneven distribution of causes of death. When the bulk of deaths are not liver function related, it just doesn't seem like an indicative metric. Not that liver function related deaths are necessarily indicative. Just that mortality rate is a rather rough metric, and when less than 2% of deaths seem to be liver function related, and liver failure related deaths not really being indicative of the effects on "strengthening" the function of <em>healthy liver</em>, mortality rates don't really answer a question on "effects of micro-dosing alcohol", but a rather specific yet deprived of specific information question on "effects on microdosing alcohol on mortality rates".</p> <p>It seems to me that such a metric would completely stifle say a 10% improvement of metabolism of toxins if the bulk of the test subjects die of unrelated conditions or even already deteriorated liver function, and that is such a case, mortality rates are about as indicative as the effects of microdosing alcohol on the chance of getting struck by lightning.</p> <p>Maybe there are more isolated and focused studies that have tested liver samples from test subjects, or a study involving the introduction of toxins to the body and measuring the speed and efficiency at which they are being handled?</p>

[ { "answer_id": 10228, "body": "<p>Drinking the appropriate amount of water is okay, but when it becomes excessive, then it could lead to some dangerous circumstances.</p>\n\n<p>The appropriate amount of water varies according to lifestyle. According to the popular 8 by 8 rule which says that one should drink eight glasses, each consisting of eight ounce of water, may not suit every individual. Says nutritionist Venu Adhiya Hirani, \"While the general belief is to drink eight to 10 glasses of water, it is advisable to drink 12 to 15 glasses of fluids which includes water, tea, buttermilk, soup, etc. This would amount to an intake of around 2.5 litres of fluids everyday.\"</p>\n\n<p>According to Krishnan, If you have a sedentary lifestyle and work in an air-conditioned environment where there is no scope for water loss via sweat, drinking more than 2 to 2.5 litres of water is not advisable. It will end up accumulating in your kidney and cause edema. For moderate workers like salespersons, who are required to do physical activity, it is important to drink around three litres of water.</p>\n\n<p>“It also depends on your size and weight, and also on your activity level and where you live,” Nessler says. “In general, you should try to drink between half an ounce and an ounce of water for each pound you weigh, every day.\" For example, if you weigh 150 pounds, that would be 75 to 150 ounces of water a day.</p>\n\n<p><a href=\"http://m.timesofindia.com/life-style/health-fitness/diet/Health-benefits-of-black-tea/articleshow/8508759.cms\" rel=\"nofollow noreferrer\">http://m.timesofindia.com/life-style/health-fitness/diet/Health-benefits-of-black-tea/articleshow/8508759.cms</a></p>\n\n<p><strong>Consequences of drinking excess water</strong></p>\n\n<p><strong>1. Causes Hyponatremia:</strong></p>\n\n<p>The sodium content in the blood influences the functioning of the electrolytes. These electrolytes are responsible for sending signals to the cells which control various operations of the body. When you consume too much water, the sodium levels in the blood decrease. This stops the electrolytes from sending signals to the cells.</p>\n\n<p><strong>2. Overburdens The Heart:</strong></p>\n\n<p>The heart performs the vital function of pumping blood through your entire body. When you consume too much of water, this increases the volume of blood inside your body. The increased blood volume causes unnecessary pressure on the blood vessels and the heart, leading to seizure in some cases.</p>\n\n<p><strong>3. Causes Damage To Glomeruli:</strong></p>\n\n<p>Glomeruli are capillary beds in our kidneys. They work as a filtering station to excrete excess water from the body. Too much of water can cause potential damage to this system, leading to serious health hazards. The kidneys have to work overtime to process all this unnecessary water that is beyond their normal filtering capacity (1000 ml per hour).</p>\n\n<p><strong>4. Causes Swelling Of Cells:</strong></p>\n\n<p>As your blood gets diluted due to excess water, the concentration of electrolytes in the blood becomes lower than that in the cells. To maintain a balance in the concentration of electrolytes in the blood and the cells, water begins to flow into the cells. This results in swelling of cells, which is a dangerous condition.</p>\n\n<p><strong>5. Causes Brain Edema:</strong></p>\n\n<p>This is the swelling of brain cells. It is as hazardous as it sounds. Most of the cells in our body have a lot of room to stretch out. But the flat bones in our skull do not leave much space for the brain cells to be accommodated freely. When excess water in the blood vessels starts seeping into the brain cells, it causes swelling in the cells of the brain. This leads to severe conditions that include coma, brainstem herniation, and respiratory attack.</p>\n\n<p><strong><em>Note:</em></strong> There has even been a <a href=\"http://www.telegraph.co.uk/news/uknews/2262683/Man-dies-after-drinking-10-litres-of-water-in-eight-hours.html\" rel=\"nofollow noreferrer\">report</a> of a man who died drinking 10 litres of water within eight hours.</p>\n", "score": 4 } ]

But that &quot;no&quot; is an oversimplification. The devil is indeed in the details.</p>\n<p>The <a href=\"https://en.wikipedia.org/wiki/Innate_immune_system\" rel=\"nofollow noreferrer\">innate immune system</a> and the <a href=\"https://en.wikipedia.org/wiki/Adaptive_immune_system\" rel=\"nofollow noreferrer\">adaptive immune system</a> have to be considered. The reasoning given in the question is in principle largely only applicable to the innate system.\nThe adaptive immune system is highly specific. When there is a response to one virus then a different virus will be new to this system. That will result in that system having to start from scratch fighting it. To make matters more complicated, both systems interact and the above explanation is almost a grossly reduced picture of what <em>might</em> be going on.</p>\n<p>It depends on what an infection is, where it occurs, what is doing the infection etc. Some <a href=\"https://en.wikipedia.org/wiki/Attenuated_vaccine\" rel=\"nofollow noreferrer\">vaccines</a> are just a perfect fit for the description in question. But to &quot;improve resistance to coming infective disease&quot; would then have to be modified into &quot;improve resistance to coming infective disease <em>of the same or very similar kind</em>&quot;.</p>\n<p>Examples against &quot;one infection protects against a second&quot; are quite numerous:</p>\n<blockquote>\n<p><a href=\"https://en.wikipedia.org/wiki/Coinfection\" rel=\"nofollow noreferrer\">In microbiology, coinfection is the simultaneous infection of a host by multiple pathogen species. In virology, coinfection includes simultaneous infection of a single cell by two or more virus particles. An example is the coinfection of liver cells with Hepatitis B virus and Hepatitis D virus, which can arise incrementally by initial infection followed by superinfection.</a></p>\n<p><a href=\"https://en.wikipedia.org/wiki/Superinfection\" rel=\"nofollow noreferrer\">A superinfection is a second infection superimposed on an earlier one, especially by a different microbial agent of exogenous or endogenous origin, that is resistant to the treatment being used against the first infection. Examples of this in bacteriology are the overgrowth of endogenous Clostridium difficile which occurs following treatment with a broad-spectrum antibiotic, and pneumonia or septicemia from Pseudomonas aeruginosa in some immuno-compromised patients.</a></p>\n<p><a href=\"https://en.wikipedia.org/wiki/HIV_superinfection\" rel=\"nofollow noreferrer\">HIV superinfection (also called HIV reinfection) is a condition in which a person with an established human immunodeficiency virus infection acquires a second strain of HIV, often of a different subtype. The HIV superinfection strain (a recombinant strain) appears when a person becomes simultaneously infected by two different strains, allowing the two viruses to exchange genetic material, resulting in a new unique strain that can possess the resistances of both previous strains. This new strain co-exists with the two prior strains and may cause more rapid disease progression or carry multiple resistances to certain HIV medications.</a></p>\n</blockquote>\n<p>On the other hand, if you define <em>infection</em> as &quot;like, having bacteria&quot; then being infected by several of them does (or at least might) protect you. That is of course a philosophical stretch in definitions for most aspects of medicine. But there is some evidence of varying degrees for bacteria, fungi, <a href=\"https://en.wikipedia.org/wiki/Bacteriophage\" rel=\"nofollow noreferrer\">different</a> forms of <a href=\"https://www.biotechniques.com/news/Viruses-Join-the-FightAgainst-Cancer/biotechniques-365925.html\" rel=\"nofollow noreferrer\">viruses</a> and <a href=\"https://health.stackexchange.com/q/11724/11231\">parasites</a> infecting – or less stretchy: colonising – a host and having more beneficial than detrimental effects.</p>\n<p>That does not only involve pure infighting between those species. (Like beneficial microbiome species outcrowding the bad ones, or producing chemicals that are toxic to the unwanted invaders, or just good ones eating the bad ones.) There is also some spillover along the lines of reasoning in the question, for example:</p>\n<blockquote>\n<p><a href=\"http://www.cell.com/immunity/abstract/S1074-7613(17)30274-1\" rel=\"nofollow noreferrer\"><strong>An Ocular Commensal Protects against Corneal Infection by Driving an Interleukin-17 Response from Mucosal γδ T Cells</strong></a>\nMucosal sites such as the intestine, oral cavity, nasopharynx, and vagina all have associated commensal flora. The surface of the eye is also a mucosal site, but proof of a living, resident ocular microbiome remains elusive. Here, we used a mouse model of ocular surface disease to reveal that commensals were present in the ocular mucosa and had functional immunological consequences. We isolated one such candidate commensal, Corynebacterium mastitidis, and showed that this organism elicited a commensal-specific interleukin-17 response from γδ T cells in the ocular mucosa that was central to local immunity. The commensal-specific response drove neutrophil recruitment and the release of antimicrobials into the tears and protected the eye from pathogenic Candida albicans or Pseudomonas aeruginosa infection. Our findings provide direct evidence that a resident commensal microbiome exists on the ocular surface and identify the cellular mechanisms underlying its effects on ocular immune homeostasis and host defense.</p>\n</blockquote>\n", "score": 4 } ]

What exactly is fever?

<p>Pyrexia (or fever) is mostly considered just high temperature, most often caused by infections. Especially in this time of the year, influenza infections that cause fever are quite common.</p> <p>I would presume that the body heats up in order to kill off bacteria (similar as to why we boil water, and cook food). This doesn't really make much sense when it comes to viruses, as they do not have a similar metabolism. Still, one symptom of influenza is pyrexia, so I conclude that pyrexia is triggered in some part of the immune system which does not differentiate between a viral and bacterial infection. I imagine pyrexia to be the body's standard response to an intruder of any kind. Am I right here?</p> <p>I also do have 2 follow up questions: How does our body increase the temperature? Is there a fail-safe mechanism (the many deaths caused by high temperature make me think there is none)?</p> <p>For those who listen to R&amp;B: I'm not looking for the song by Peggy Lee (which is great, by the way)</p>

[ { "answer_id": 11334, "body": "<blockquote>\n <p>All models are wrong, but some are useful.</p>\n</blockquote>\n\n<p>The same is true for the body mass index. In general, people with a higher BMI have a higher chance of getting obesity-related illnesses than those with a BMI in the 18-25 range. But of course, there are exceptions like the one you mention. That's no reason to discard the entire BMI, because it does work in many cases. It's easier than other predictors (such as abdominal circumference).</p>\n\n<p>Another example would be age, as a predictor of mortality. It's safe to assume that in general, a 90-year-old would die sooner than a 25-year-old. But it's not true that no 25-year-olds die before any 90-year-old.</p>\n\n<p>For the second part of your question: obesity is defined as a BMI >30. In that sense, we can say that Heath would be obese. But once again, this \"label\" is not flawless. He's probably got a lower probability of getting obesity-related illnesses than someone with a BMI of 29.9 based entirely on a bad diet and lack of exercise. </p>\n\n<p>TL:DR; BMI isn't a flawless predictor, but it's ease-of-use causes it to still be used.</p>\n", "score": 6 }, { "answer_id": 11365, "body": "<p>Let's not conflate two different problems with BMI here. One the one hand you can have a low body fat percentage and still have a high BMI, but that only applies to body builders who exercise at a near professional level. Such a person will not get wrongly diagnosed by his or her doctor of being overweight. So, this shouldn't be a problem, however, as Carey Gregory points out, some insurance companies in the US make decisions about coverage and premiums purely based on BMI, which can lead to unjust decisions. A more practical problem with BMI is that it will underestimate the risk of cardiovascular problems and diabetes in people of certain ethnicities, particularly Asians. As <a href=\"http://www.who.int/nutrition/publications/bmi_asia_strategies.pdf\" rel=\"nofollow noreferrer\">recommended by the WHO</a>, Asians should keep their BMI below 23 kg/m^2.</p>\n\n<p>Then having cleared up these two real issues with the BMI, let's consider the context in which the argument for a fat tax and the denial of medical services are made in the sources quoted by the OP. The medical problem that at hand is that health problems caused by a poor diet combined with lack of exercise account for the lion's share of health care costs. The US is a special case where 50% of the health care costs is due to an inefficient system, in most other Western countries, the burden of health care costs to society is about 10% of GDP. But even that 10% of GDP is mostly due to people eating too much fat, salt and sugar and not doing enough exercise.</p>\n\n<p>The people who choose to eat too many Big Macs are not only making me pay for my health care, they are actually limiting my health care options. The health care industry is hard at work at fixing the bodies of people who through their own faults, have wrecked their bodies, therefore I don't have to count on being treated in an optimal way. If at age 90 I would need a new kidney, I will be rejected because of my age despite having the fitness of a 60 year old by that time. </p>\n\n<p>There are also costs for society outside of health care. Your car is <a href=\"https://www.youtube.com/watch?v=nj8-cGh9FsE&amp;feature=youtu.be&amp;t=1171\" rel=\"nofollow noreferrer\">significantly more expensive</a> because the workers at the factories where cars are made are not making the right lifestyle choices. If you buy a plane ticket, you're paying more because transporting heavier people requires more fuel, the costs are shared by all passengers; people only pay for their extra checked luggage above their allowance, not your checked fat. <a href=\"https://www.youtube.com/watch?v=BlILHQ0DXFA\" rel=\"nofollow noreferrer\">This has led to calls for the system to be modified</a>. The fat tax mentioned here is a fee that overweight people would have to pay. Contrast that with the notion of a \"fat tax\" in the source quoted by the OP. There it's about imposing a VAT on fat, which is a reasonable way to get the population to stick to a healthier lifestyle, thereby drastically reducing the costs incurred on society. </p>\n\n<p>In conclusion, while it may look like the BMIs of very muscular athletic people poses a problem with using the BMI, a closer examination of the relevant facts reveals that this is not a major problem. Rather, it are obese people whose BMIs do actually reflect their miserable physical state (and also people with a normal weight who eat an unhealthy diet) who are making everyone pay a hefty fat tax, and they are making the quality of the health care available for you a lot worse.

How to stop panic?

<p>I feel fear when I should talk to a girl or do my exams or do things I am obliged to do. It happens in the morning, I wake up with fear and I can't handle the situation. My thoughts are negative and I can't do anything to change it.</p> <p>I have talked to two doctors; one's solution was to take pills and the other to do a physical program and a healthy diet that will do my body better. I find both solutions wrong. </p> <p>For the first, I think I will depend on the pills and when I face a more difficult situation, I will need more a powerful pill. I could harm myself with those, right? For the second, maybe I'll be healthier but I believe a healthy diet will not improve the situation of this panic. </p> <p>What can I do now?

How to keep the brain in an excited state?

<p>When the brain is excited everything is all around better, learning is faster, training is better, socializing is easier and thinking is faster and more coherent.</p> <p>For some, such as myself, however, this is not a natural state, indeed it is very rare.</p> <p>I have, in the past, suffered from major depression, and while I learned to control this seemingly normal state of mind, it seems that much of my brain is still "off" leading me to believe that neuron firing in my brain may be inhibited.</p> <p>Now, I have considered a number of methods for dealing with this problem amoung which are: </p> <ul> <li><p>SSRIs: The problem doesn't seem to be seratonin deficiency, which prompted me to stop. </p></li> <li><p>Marijuana: While it does help with the depressive mental states, it only replaces them with vegetative states which is not optimal.</p></li> <li><p>Cocaine: Ruled out due to high costs and risk of addiction.</p></li> <li><p>Various epinephrines: Ruled out due to the potential shut down of natural epinephrine production in the brain.</p></li> </ul> <p>All these drugs are seemingly unworkable and in fact, music is the only thing capable of producing excitatory responses in my brain, though they happen rarely and seldom last for longer than a few hours, however the very fact that they happen may be indication that a more permanent excitatory state is possible.</p> <p>Furthermore, I would like to place what you've read thus far into context, I am not looking for a permanent "high" which you might associate with some of the aforementioned drugs, while that may be a dream state for a drug addict, it is not for me.

It points out that sugars are linked to dental problems (cavities) and that eating unrefined grains (eg whole wheat, brown rice) is associated with a lower risk of diabetes and heart issues. It also emphasizes the importance of fibre.

<p>All of the bread made in my bread-making course uses White flour. They come out nice &amp; white, crusty &amp; chewy. Tastes great too!

[ { "answer_id": 14284, "body": "<p>Yes. There are scientific reasons and treatments involving worms and allergies or other immune system disorders. But the results are not overly conclusive and still understudied.</p>\n<p>This is based on the so called <a href=\"https://en.wikipedia.org/wiki/Hygiene_hypothesis\" rel=\"nofollow noreferrer\">hygiene hypothesis</a> in immunology.</p>\n<p>Short version to this: our immune system evolved in a world full of dirt and germs where it had to be quite aggressive against all those threats and invasions in order to keep our ancestors alive. In recent years – since Leuwenhoek, Semmelweiss, Lister, Koch and Pasteur – we learned that and how germs could make us ill and tried to eradicate all of them. Or at least keep them away from us as to limit the danger of getting infections.</p>\n<p>That would theoretically translate into the very simple reasoning: Trying to eliminate all germs, or improving hygiene, ensures a much healthier population across the board. But the problem observed was that allergies were on the rise into previously unheard of dimensions despite the direct living environments getting cleaner and cleaner. That is, in modernised or Western societies allergies have become very widespread. In less developed nations the rise of allergies was seen as much less pronounced.</p>\n<p>The hypothesis is now that a lack of actual threats and &quot;proper training&quot; is directing the immune system to attack otherwise rather benign substances (like pollen) or even the own tissues (auto-immune disorders). Turning this process from its head back to its feet again it was then tried whether a deliberate infestation with once very common hookworms might alleviate the symptoms of sufferers. And apparently it sometimes did.</p>\n<p>Apart from currently being still <em>very</em> promising there are downsides to its applications. The effects seem to rely quite heavily on early childhood exposure and diminish with age. Having a worm is not much fun and of course, once the worms have &quot;modulated the immune system&quot; you have to get treatment to get rid of them again (which might cause an impressive range of side-effects on its own; <a href=\"https://www.drugs.com/sfx/vermox-side-effects.html\" rel=\"nofollow noreferrer\">example</a>).</p>\n<p>And while overuse of certain hygienic agents, like disinfectants and antibiotics, are certainly a problem, cutting back radically on hygiene or even to introduce deliberate infections of any kind seem like an easy inference – and a bat droppings crazy stupid one on top. It's complicated and we're still figuring out much of the basics.</p>\n<p>Good overviews are presented here: <a href=\"http://www.bbc.com/future/story/20130422-feeling-ill-swallow-a-parasite\" rel=\"nofollow noreferrer\">Worm therapy.

This whole concept is now even largely superseded (or <a href=\"https://www.nature.com/articles/ni.3829\" rel=\"nofollow noreferrer\">refined</a>?) with the <a href=\"https://www.news-medical.net/health/Old-Friends-Hypothesis.aspx\" rel=\"nofollow noreferrer\">Old Friends hypothesis</a>, including bacteria and even viruses. This presents a much more <em>re</em>-balanced view of &quot;us&quot;– taking for example also our whole microbiome into consideration and not just a few &quot;key players&quot; like the hookworm in question.</p>\n<p>More up-to-date and in a more scientifically constructed wording than the gross oversimplifications above are these papers:</p>\n<p><a href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2680069/\" rel=\"nofollow noreferrer\">Interactions between helminth parasites and allergy</a>(2009)</p>\n<blockquote>\n<p>Helminth infections have strong modulatory effects on anti-parasite inflammatory responses in the human host but it is not clear if helminths can affect allergic inflammatory responses to aero-allergens. Helminth infections have been associated with both a reduced prevalence and increased prevalence of atopy and atopic disease in different populations. The immune regulatory effects of tissue helminths are likely to be stronger than those of geo-helminths. Further research in prospective observational and intervention studies is required to address the question of causality. An understanding of the mechanisms by which helminth parasites modulate the host allergic inflammatory response may lead to the development of novel anti-inflammatory interventions. The demonstration of a causal association between some helminth parasites (particularly geo-helminths and toxocariasis that have a worldwide distribution) and an increased risk of asthma could lead to anthelmintic treatment programmes in populations considered to be at high risk.</p>\n</blockquote>\n<p><a href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5025185/\" rel=\"nofollow noreferrer\">The Hygiene Hypothesis and Its Inconvenient Truths about Helminth Infections</a>(2016)</p>\n<blockquote>\n<p>Current iterations of the hygiene hypothesis suggest an adaptive role for helminth parasites in shaping the proper maturation of the immune system. However, aspects of this hypothesis are based on assumptions that may not fully account for realities about human helminth infections. Such realities include evidence of causal associations between helminth infections and asthma or inflammatory bowel disease as well as the fact that helminth infections remain widespread in the United States, especially among populations at greatest risk for inflammatory and autoimmune diseases.</p>\n</blockquote>\n<p>That means that the parasites are well known to be able to modulate the immune system response. But this does not translate into proven, always beneficial effects. It can also go very wrong and actually worsen any associated condition. We do not know with certainty how the parasites do it. We do not know with certainty which parasites might be good or bad for what. We do not know with certainty if early exposure (at a young age), where the observed effects seem strongest, is necessary and therefor a treatment for adults much less effective. Having parasites is not very pleasant, just copying their mechanism looks much more promising.</p>\n<blockquote>\n<p>A recently emerged attractive alternative hypothesis to explain the rise of inflammatory diseases is a <a href=\"http://www.bmj.com/content/349/bmj.g5267\" rel=\"nofollow noreferrer\">“biome depletion” theory</a>. This suggests inflammatory disease may be due to a loss of species diversity or alteration of composition of the commensal microbiome within the human body.</p>\n<p>The immense conflicting data regarding the benefits versus harms of live helminths as a therapeutic modality to date warrants further questioning of the utility of additional human clinical trials. Therefore, directing future research and trials towards helminth-derived immunomodulatory molecules allows for safer and better-described therapies that could alleviate the suffering from autoimmune conditions without the commensurate risk of a parasite infection. Indeed, the aim of experimental animal models should be to develop novel treatments that mimic the effects of helminths without requiring the presence of parasites in the host.</p>\n</blockquote>\n<p><a href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4374592/\" rel=\"nofollow noreferrer\">Human helminth therapy to treat inflammatory disorders – where do we stand?</a> (2015)</p>\n<blockquote>\n<p>Parasitic helminths have evolved together with the mammalian immune system over many millennia and as such they have become remarkably efficient modulators in order to promote their own survival. Their ability to alter and/or suppress immune responses could be beneficial to the host by helping control excessive inflammatory responses and animal models and pre-clinical trials have all suggested a beneficial effect of helminth infections on inflammatory bowel conditions, MS, asthma and atopy. Thus, helminth therapy has been suggested as a possible treatment method for autoimmune and other inflammatory disorders in humans.</p>\n</blockquote>\n<p>Especially in relation to asthma:\n<a href=\"https://autoimmunetherapies.com/candidate_diseases_for_helminthic_therapy_or_worm_therapy/asthma_helminthic_therapy.html\" rel=\"nofollow noreferrer\">Asthma &amp; Helminthic Therapy.

Does eating too much cocoa have harmful side effects?
[ "nutrition", "food-safety", "overdose" ]
<p>My question concerns the consumption of pure, unsweetened cocoa. The cocoa to be consumed could either be boiled or mixed with tap water. Its consistency could range from buttery to creamy to soda-like. I could consume the cocoa without any sweeteners or other additives, although occasionally I might add a dash of cinnamon or other spice or even a teaspoon of peanut to sweeten it up a bit. Leaving aside the dietary limits for these occasional additives, is there a practical limit to the amount of cocoa a healthy person could consume per day?</p> <p>I understand that eating a kilo of anything, even so-called "super foods", could make you sick, but as a practical diet plan, I'm thinking of a regimen that consists of oatmeal with cocoa for breakfast, a lunch of cocoa-coated veggie fries, chilled cocoa with peanut butter or whipped cream for my dinner dessert, and the usual sauces and dips made out of cocoa. In short, every meal will have the dark brown powder as an ingredient.</p> <p>This isn't an entirely hypothetical question. I've adopted a cocoa-based diet as a means of curbing my unhealthy craving for sweets, having recently learned I have symptoms of prediabetes. By accident I discovered that after eating extra dark chocolate I found my usual bland banana super sweet. After several days of trial, I found I could drink my usual chilled breakfast cocoa without adding milk. The net effect is that I could have a satisfying "dessert" that consists entirely of a teaspoon of skim milk and cinnamon, one-third cup oats diluted in water, and flavored by three tablespoons of cocoa powder!</p>

But it's really important to realize that screening brings false positives. These cause distress and anguish to people who believe they are dying and they cost a lot of money because the investigations required are expensive and intrusive.</p>\n\n<p>Recently Ontario has stopped recommending women do monthly breast self exams. These are free. However they do not save any lives. Women who actually have lumps find them without dutifully checking every month or week for them. But with the regular screening, many find things that are not cancers. They need to take time off work, get biopsies, which can be inconclusive, get scans, even have surgery to remove lumps so they can be sent to pathology, and so on. This costs a lot of money directly to the hospital and indirectly in people being off work. All this expense is pointless: there is no difference in survival rates between groups who do BSE and those who do not.

Both the screening and the procedures that happen when someone screens positive can hurt or kill people if you screen everyone, meaning millions of people.</p>\n\n<p>Finally, while it may seem logical to you that screenings like this would save lives by catching things earlier, there is very little evidence to support that. Our bodies actually destroy small cancers all the time: just because you see a small cancer on a scan doesn't mean the huge treatment machine has to swing into action.

Wound care specialist says “it has healed too much, now it can’t heal”
[ "wound-care" ]
<p>I had three surgeries this summer, the last surgery was 11 weeks ago. The incision is small, about 2 inches, and started to heal fine at one end. The other end rejected 3 stitches which were pulled and drained for 3-4 weeks. Since, the wound has been healing very slowly (it is still bleeding slowly and is open). The surgeon has said that it is progressing the entire time, but progress has been very slow. They recommended me to a wound care office. </p> <p>Yesterday at the wound care office they treated the unhealed part with Silver Nitrate and prescribed a silver based ointment to put under their bandage. </p> <p>When I pressed the doctor on what was happening that slowed the healing process and required the nitrate treatment, she wouldn’t give any specifics. She only said “the wound has healed too much, and now it can’t heal anymore without knocking it back first.” I asked for more details and got a similar response back. </p> <p>Can anyone give me some clarification as to the biological process going on and what the nitrate treatment is supposed to accomplish? </p> <p>Thanks </p>

These recommendations may also be dependent on training status: experienced athletes would require less, while more protein should be consumed during periods of high frequency/intensity training. Elevated protein consumption, as high as 1.8–2.0 g · kg−1 · day−1 depending on the caloric deficit, may be advantageous in preventing lean mass losses during periods of energy restriction to promote fat loss.</p>\n</blockquote>\n<p>That article is an excellent read, and contains many links and references to studies on various protein intakes for low to elite level athletes and body builders.</p>\n<p>From <a href=\"https://bayesianbodybuilding.com/the-myth-of-1glb-optimal-protein-intake-for-bodybuilders/\" rel=\"nofollow noreferrer\">another very well written article</a>:</p>\n<blockquote>\n<p>To check if maybe there still isn't a slight benefit of going higher in protein that all these studies couldn't find, I co-authored a meta-analysis with some of the world's leading fitness researchers. We again a cut-off point at exactly 1.6g/kg/d beyond which no further benefits for muscle growth or strength development are seen.</p>\n<p>Based on the sound research, many review papers have concluded 0.82g/lb is the upper limit at which protein intake benefits body composition (Phillips &amp; Van Loon, 2011). This recommendation often includes a double 95% confidence level, meaning they took the highest mean intake at which benefits were still observed and then added two standard deviations to that level to make absolutely sure all possible benefits from additional protein intake are utilized. As such, this is already overdoing it and consuming 1g/lb ”˜to be safe' doesn't make any sense. 0.82g/lb is already very safe.</p>\n</blockquote>\n<p>Examining the article you link in the question, the end includes:</p>\n<blockquote>\n<p>Even though a higher protein intake can have health benefits for many people, it is not necessary for everyone.\n<strong>Most people already eat protein at around 15% of calories, which is more than enough to prevent deficiency</strong>.\nHowever, in certain cases, people can benefit from eating much more than that, or up to 25-30% of calories.</p>\n</blockquote>\n<p>(Emphasis mine)</p>\n<p>It then links to an article on &quot;how much protein you should be eating&quot;, which notes:</p>\n<blockquote>\n<p>A common recommendation for gaining muscle is 1 gram of protein per pound of body weight, or 2.2 grams of protein per kg.\nNumerous studies have tried to determine the optimal amount of protein for muscle gain and many of them have reached different conclusions.\nSome studies show that over 0.8 grams per pound has no benefit (13), while others show that intakes slightly higher than 1 gram of protein per pound is best (14).\n<strong>Although it's hard to give exact figures because of conflicting results in studies, 0.7-1 grams (give or take) per pound of body weight seems to be a reasonable estimate</strong>.</p>\n</blockquote>\n<p>(Emphasis mine)</p>\n<p>So while all the articles agree that a general intake of around 1g/lb/day is the upper limit of beneficial, they also agree that in specific diets and goals, increasing the amount of protein can aid in weight loss and lean mass retention.

Another retrospective cohort study of children aged 6 months through 8 years, the majority of whom received IIV3 (0.8% received LAIV3), also conducted during the 2003–04 season, found no effectiveness against ILI among children who had received only 1 dose (140). In a case-control study of approximately 2,500 children aged 6–59 months conducted during the 2003–04 and 2004–05 seasons, being fully vaccinated (having received the recommended number of doses) was associated with 57% effectiveness (95% CI = 28–74) against LCI for the 2004–05 season; a single dose was not significantly effective (too few children in the study population were fully vaccinated during the 2003–04 season to draw conclusions) (141). </sub> <br> The results of these studies support the recommendation that all children aged 6 months–8 years who are being vaccinated for the first time should receive 2 doses separated by at least 4 weeks.

Why are two influenza vaccinations required for people under a certain age?
[ "immune-system", "vaccination", "influenza" ]
<p>According to the CDC, people under 8 who have never had the flu vaccine or flu should get 2 doses at least 28 days apart. The reason given is that "the first dose 'primes' the immune system," but as far as I know "primes" is not a medical term in this context.</p> <p>What exactly does "'primes' the immune system" mean here?

The samples were cut into 1-inch circles and maintained in a hydrated state by floating the samples (dermal side down) on a water bath. The absorbance of each skin sample was measured and recorded. Ten microliters (L) of sunscreen were applied to the skin substrate, allowed to dry for 15 minutes, and the absorbance measured. The absorbance of each sunscreen treated sample was subtracted from the absorbance of the skin (without sunscreen) to yield the absorbance of the sunscreen.

These spectral profiles of zinc oxide in various formulations demonstrated that</p>\n\n<blockquote>\n <p>...zinc oxide as a single ingredient can provide protection in both the UVB and UVA spectral regions.</p>\n</blockquote>\n\n<p>Recent scientific advances in understanding the photochemistry and photobiology of sunscreen drug products have raised many issues regarding sunscreen active ingredients, including zinc oxide and titanium dioxide. Because zinc oxide and titanium dioxide have many similar physical characteristics and may be used in combination in OTC sunscreen drug products, the following discussion addresses both ingredients.</p>\n\n<blockquote>\n <p>There has been renewed interest in using physical sunscreens, i.e., zinc oxide and titanium dioxide, in sunscreen formulations because these ingredients may confer protection for a broad range of the UV radiation spectrum. Some manufacturers have developed ultrafine forms of these ingredients in the range of 0.02 to 0.10 microns that are transparent on the skin, may offer both UVA and UVB protection, and are esthetically pleasing…</p>\n</blockquote>\n\n<p>Sunscreens have been generally classified as chemical (organic) or physical (inorganic) depending on whether they absorb specific UV radiation wavelengths or reflect and scatter UV radiation.</p>\n\n<blockquote>\n <p>Zinc oxide and titanium dioxide have been described as physical sunscreen ingredients that provide protection from UV radiation through reflection and scattering. However, new data and information indicate that they also absorb UV radiation as well as scatter visible light.</p>\n</blockquote>\n\n<p>Various authors have shown that these ingredients exhibit a semiconductor optical absorption gap meaning they absorb most radiation at wavelengths shorter than the gap (approx. 380nm) and scatter radiation at wavelengths longer than the gap.</p>\n\n<blockquote>\n <p>When zinc oxide and titanium dioxide are irradiated with light containing energy greater than the band gap (approximately 3 electron volts), an electron from the valence band can be excited to the conduction band, thus creating an electron-hole pair.</p>\n</blockquote>\n\n<p>There are many formulation variables that may affect the photocatalytic capability of zinc oxide and titanium dioxide.</p>\n\n<blockquote>\n <p>Such variables include mineral components, particle size, surface area, crystalline structure, particle coatings, pH of the medium, differences in the refractive index of the medium, and other components in the formulation.</p>\n</blockquote>\n\n<p>Although the FDA continues to evaluate data and information for the purpose of proposing a monograph method for determining UVA radiation protection, it nonetheless finds</p>\n\n<blockquote>\n <p>there is ample data demonstrating that zinc oxide provides protection against UVA radiation.</p>\n</blockquote>\n\n<p>As it relates to the frequency one should apply sunscreen, a common recommendation by many public health agencies is to reapply sunscreen every <em>two to three hours</em>.

For sunscreens that bind moderately or well to skin, typical of modern waterproof or water-resistant products, the lowest skin exposure results from early reapplication into the sun exposure period, and not at 2 to 3 hours, after initial application. Typically reapplication of sunscreen at 20 minutes results in 60% to 85% of the ultraviolet exposure that would be received if sunscreen were reapplied at 2 hours.</p>\n</blockquote>\n\n<p>The concluding statement advises sunscreen users </p>\n\n<blockquote>\n <p>…to apply sunscreen liberally to exposed sites 15 to 30 minutes before going out into the sun, followed by reapplication of sunscreen to exposed sites 15 to 30 minutes after sun exposure begins. Further reapplication is necessary after vigorous activity that could remove sunscreen, such as swimming, toweling, or excessive sweating and rubbing.</p>\n</blockquote>\n\n<p>Another abstract, ‘<a href=\"https://www.ncbi.nlm.nih.gov/pubmed/15767357\" rel=\"noreferrer\">A noninvasive objective measure of sunscreen use and reapplication</a>’, studied whether a noninvasive swabbing technique can detect sunscreen use for up to 6 hours, and whether the technique can detect reapplication of sunscreen. </p>\n\n<blockquote>\n <p>Thirty volunteer office workers were randomly assigned to have one of a variety of sunscreens applied using recommended application techniques, and half were randomly assigned to have sunscreen reapplied after 3 hours. Alcohol-based swabs were used to obtain a sample from participants' arm at 20 minutes, and hourly from 1 to 6 hours post-application. Absorption readings were analyzed using an UV-visible spectrophotometer…The “swabbing technique” was consistently able to distinguish the sunscreen from control swabs for up to 6 hours.

No differences in absorption readings were found with sunscreen reapplication. This procedure will be a useful adjunct to other objective measures of sun protection and UV radiation exposure, resulting in a more accurate picture of the sun protection habits of individuals.</p>\n</blockquote>\n\n<p>Moreover, the Skin Cancer Foundation answers several relevant questions in an article titled ‘<a href=\"http://www.skincancer.org/prevention/sun-protection/sunscreen/sunscreens-explained\" rel=\"noreferrer\">Sunscreens Explained</a>’. </p>\n\n<blockquote>\n <p>How much Sunscreen Should I Use and How Often Should I Put it On?\n To ensure that you get the full SPF of a sunscreen, you need to apply 1 oz – about a shot glass full. Studies show that most people apply only half to a quarter of that amount, which means the actual SPF they have on their body is lower than advertised. During a long day at the beach, one person should use around one half to one quarter of an 8 oz. bottle. Sunscreens should be applied 30 minutes before sun exposure to allow the ingredients to fully bind to the skin. Reapplication of sunscreen is just as important as putting it on in the first place, so reapply the same amount every two hours. Sunscreens should also be reapplied immediately after swimming, toweling off, or sweating a great deal.</p>\n</blockquote>\n\n<p>Finally, to address your question: “Why do I need to reapply a zinc sun blocker if it has not been exposed to sun or sweat?”; The International Agency for Research on Cancer’s ‘<a href=\"http://www.iarc.fr/en/publications/pdfs-online/prev/handbook5/index.php\" rel=\"noreferrer\">IARC Handbook of Cancer Prevention Volume 5</a>,’ explains in Chapter 6: <a href=\"http://www.iarc.fr/en/publications/pdfs-online/prev/handbook5/Handbook5_Sunscreens-6.pdf\" rel=\"noreferrer\">Other beneficial effects of sunscreens</a>, that there are other potential beneficial effects of sunscreens that are not related to the prevention of skin cancer include prevention of painful sunburns, photodamage and photoageing UVR-induced provocation of certain cutaneous diseases, and photoimmune suppression.</p>\n\n<blockquote>\n <p>Use of sunscreens can prevent skin diseases from progressing acutely after exposure to the sun; these diseases include cutaneous lupus erythematosus…and reactivation of herpes labialis… The other potential benefits of sunscreens are related to the type and duration of exposure to UVR. Prevention of photodamage and photoageing, which are related to cumulative exposure to UVR, in countries where solar irradiance is intense throughout the year requires daily, longterm sun protection… Prevention of acute flares of cutaneous diseases, which may be related to episodic exposure to UVR, requires anticipatory use of sun protection.</p>\n</blockquote>\n\n<p>Under certain circumstances, diseases of various etiologies can be aggravated by sunlight in people who on other occasions may react normally.</p>\n\n<blockquote>\n <p>These diseases include lupus erythematosus, lichen planus and herpes simplex. The disease most frequently recognized as requiring careful photoprotection from both UVB and UVA is lupus erythematosus in the discoid, systemic and subacute forms…The available evidence suggests that regular use of sunscreens reduces morbidity from both cutaneous and systemic lupus erythematous.</p>\n</blockquote>\n\n<p>Therefore, if you are unsure about whether it is necessary to wear sunscreen indoors, you may want to consider your medical history and potential predisposition toward developing a disease that may increase the need for more intensive \"sun-blocking\" protective measures.

Sanity checking airplane advice re DVT: walk every hour, 2-3 hours? OK to sleep?
[ "travel", "thrombosis" ]
<p>Long plane flights carry a risk of DVT. It is easy to find advice on preventing DVT by being active:</p> <ul> <li><a href="https://wwwnc.cdc.gov/travel/page/dvt" rel="nofollow noreferrer">CDC</a> says "walk around every 2-3 hours" and mentions that you should do this when traveling by car also. This article also mentions that you are at higher risk of DVT if you have active cancer or are receiving chemotherapy. It recommends compression socks, too. </li> <li><a href="https://www.mayoclinic.org/diseases-conditions/deep-vein-thrombosis/symptoms-causes/syc-20352557" rel="nofollow noreferrer">Mayo clinic</a> says "If you're traveling a long distance by car, stop every hour or so and walk around. If you're on a plane, stand or walk occasionally."</li> <li><a href="https://www.webmd.com/dvt/tc/preventing-deep-vein-thrombosis-from-travel-topic-overview" rel="nofollow noreferrer">WebMD</a> says "If you are traveling by car, stop every hour or so. Get out and walk around for a few minutes. If you are traveling by bus, train, or plane, get out of your seat and walk up and down the aisle every hour or so. "</li> </ul> <p>None of these mention the possibility of sleeping on the plane. Are they suggesting you should not sleep? We all lie down for 8 hours or so every night, and yes, we can toss and turn a little more freely in a real bed, but I find it hard to imagine this advice means "don't sleep, stay awake so you can walk around a lot."</p> <p>Further, there is a big difference between "every hour" and "every two or three hours" - and that's not counting good old "occasionally". None indicate whether wearing compression socks means it's safer to go for a longer interval between walks. </p> <p>So, if a person with at least some risk factor for DVT is going on a long (11 hrs) flight, wearing compression socks, in business with a lie-flat bed, is lying flat in that bed and sleeping actually as dangerous as sitting awake in economy? What about a 13 hour flight in economy, still with the socks, is sleeping for part of that flight dangerous? This is normal sleep without the aid of Ambien or even alcohol, and thus there will be tossing and turning.</p> <p>Why I'm asking: I have those flights in my future and a doctor told me emphatically to get up "every hour" on the plane and walk around. I didn't think to ask about sleep time, and I have no problem getting up once an hour while awake. But this same doctor knows that I drive two to three hours to and from my appointments, and has never said to pull over the car and walk every hour during a drive. Yet DVT isn't related to altitude, just to sitting still. So I feel the "every hour" is probably a little overcareful. But I am interested in what the studies show, and specifically on the matter of sleeping, in business and in economy. I am not asking for a diagnosis or to override my doctor's advice. I just want to sanity check it since we didn't discuss economy vs business and lying down to sleep. A study showing the effects of following various advice regimens (and that includes overnight flights where people slept or stayed awake) would be great.</p>

She is then a carrier of the disease: there is a 50-50 chance of her son (to whom she gives one X) is a haemophiliac.

Increased dentate gyrus neurogenesis or HGH production are interesting results, but it's unclear that those translate into meaningful benefits for you. The papers that are worth changing your daily habits for are the ones that look at endpoints that are meaningful to you: weight loss, increased survival, improved memory, etc. While you can theorize a link between neurogenesis or HGH and a meaningful outcome, science is full of theoretical connections that turned out not to exist in real life.</p>\n\n<p><strong>Evidence for Intermittent Fasting In Humans</strong>\nThere is not yet great evidence on the topic, as you mentioned, but there is a decent review published in 2014 comparing calorie restriction (CR) diets with intermittent fasting or alternate day fasting (IF/ADF) diets. It concludes (emphasis mine):</p>\n\n<blockquote>\n <p>Results reveal <strong>superior decreases in body weight by CR</strong> vs IF/ADF\n regimens, yet <strong>comparable reductions in visceral fat mass</strong>, fasting\n insulin, and insulin resistance.

https://medicalsciences.stackexchange.com/questions/15346/is-cognitive-behavioral-therapy-actually-effective
[ { "answer_id": 15347, "body": "<p><strong>YES</strong>, according to:\n<a href=\"https://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0072481/\" rel=\"nofollow noreferrer\">The National Center for Biotechnology Information (NCBI) of the United States</a> </p>\n\n<p>and\n<a href=\"https://www.nhs.uk/conditions/cognitive-behavioural-therapy-cbt/how-it-works/\" rel=\"nofollow noreferrer\">National Heath Service (NHS) of the United Kingdom.</a></p>\n\n<p>Cognitive Behavioral Therapy is a clinically approved method to treat depression, <strong>without the usage of medication.</strong></p>\n\n<p>Cognitive behavioral therapy (CBT) is a common and well-studied form of psychotherapy, combining cognitive and behavioral therapy.</p>\n\n<p>The goal is to reveal and change false and distressing beliefs, because it is often not only the things and situations themselves that cause problems, but the importance that we attach to them too.</p>\n\n<p>For example, a dangerous thought pattern might be when somebody immediately draws negative conclusions from an occurrence, generalizes them and applies them to similar situations. In psychology, this generalized way of thinking is called “over-generalizing.” Another distressing error in reasoning is “catastrophizing”: If something disturbing happens, people immediately draw exaggerated conclusions about the scope of the supposed disaster ahead.</p>\n\n<p>Such thought patterns can sometimes develop into self-fulfilling prophecies and make life difficult for the people affected. Cognitive therapy helps people learn to replace these thought patterns with more realistic and less harmful thoughts. It also helps people to think more clearly and to control their own thoughts better.</p>\n\n<p><strong>How does behavioral therapy work?</strong></p>\n\n<p>Behavioral therapy assumes that human behavior is learned and can therefore be unlearned or relearned and aims to find out whether certain behavioral patterns make your life difficult or intensify your problems. In the second step you work on changing these behavioral habits.</p>\n\n<p>For example, people who have developed depressive thoughts often tend to withdraw and give up their hobbies. As a result, they feel even more unhappy and isolated. Cognitive therapy helps to identify this mechanism and find ways to become more active again.</p>\n\n<p>Cognitive behavioral therapy focuses on current problems and finding solutions for them. It is much more concerned with dealing with current problems. The most important thing is helping people to help themselves: They should be able to cope with their lives again without therapy as soon as possible. This does not mean that cognitive behavioral therapy completely ignores the influence of past events. But it mainly deals with identifying and changing current distressing thought and behavioral patterns.</p>\n\n<p>As an example, in anxiety disorders, behavioral therapy often includes learning methods to help you calm down. For example, you can learn to reduce anxiety by consciously breathing in and out deeply so that your body and breathing can relax. When doing this you concentrate on your breathing instead of what is bringing on your anxiety. These kinds of techniques can help you to calm down instead of getting all worked up with anxiety.</p>\n\n<p><strong>When is cognitive behavioral therapy an option?</strong></p>\n\n<p>Cognitive behavioral therapy is used to treat conditions such as depression, anxiety and obsessive-compulsive disorders, and addictions.</p>\n\n<p>Cognitive behavioral therapy requires the patient's commitment and own initiative. Therapy can only be successful if the patient actively takes part in the treatment and also works on their problems between sessions. This can be a considerable challenge, especially with severe conditions such as depression or anxiety disorders. That is why medication is sometimes used at first to quickly relieve the worst symptoms so that psychotherapy can be started.</p>\n\n<p>Choosing a certain kind of psychotherapy also depends on the goals. If you feel the need for deep insight into the causes of your problems, cognitive behavioral therapy is probably not the right choice. It is particularly useful if you are mainly interested in tackling specific problems and are only secondarily concerned with the “why.”</p>\n\n<p><strong>How long does it take?</strong></p>\n\n<p>It is important that you and your psychotherapist have a close and trusting working relationship. It can sometimes take a while to find the right therapist.</p>\n\n<p>In the first session, you will briefly explain your current problems and outline your expectations. That forms the basis for discussing the goals of therapy and the therapy plan. The plan can be adjusted if your personal goals change over the course of therapy.</p>\n\n<p>Therapy often includes recording your own thoughts in a journal over a certain period of time. The therapist will then check the following things with you: Do I perceive things appropriately and realistically? What happens if I behave differently than I normally do in a certain situation? You will regularly discuss any problems you may have and progress that you have made.</p>\n\n<p>Cognitive behavioral therapy also uses relaxation exercises, stress and pain relief methods, and certain problem-solving strategies.</p>\n\n<p>Some people already feel much better after a few sessions, while others need treatment for several months. This depends on the kind and severity of the problems, among other things. An individual session lasts about an hour. Sessions usually take place once a week. Cognitive behavioral therapy is offered in psychotherapy practices, hospitals and rehabilitation clinics- sometimes also offered as group therapy.</p>\n\n<p><strong>Can cognitive behavioral therapy also have side effects?</strong></p>\n\n<p>Side effects resulting from psychotherapy cannot be ruled out. Being directly confronted with your problems or anxieties may be very stressful at first, and relationships might also suffer as a result. It is crucial to speak openly with your psychotherapist if any difficulties come up during therapy.</p>\n\n<blockquote>\n <p>'We saw that a third of people had a difficult memory resurface, had\n more anxiety, or felt stressed.

This has been one of the criticisms levelled at CBT, that its 'one size fits all' approach to the complex nature of human problems will, inevitably, fail to meet the needs of many, or (at best), simply focus on symptom reduction. (Reeves, 2013)</p>\n</blockquote>\n\n<p>There are a fair few factors which can prevent CBT from becoming effective, and a trained and certified CBT practitioner will be able to assess the suitability of CBT. If they operate ethically, they will not go ahead with providing CBT to someone who it would not benefit.</p>\n\n<p>One of the biggest factors which doesn't allow CBT to work is that if the client is not willing <strong>or able</strong> to challenge their thoughts and behaviours, then CBT will not be effective.</p>\n\n<h2>Long answer</h2>\n\n<p>For the long answer, which will help to explain <strong>some</strong> of the reasons why CBT may not work with some people, I will be using a lot of the work I put into an essay I had to write for my psychotherapy course which covered Cognitive Behavioural Therapy (CBT) and <a href=\"http://www.counselling-directory.org.uk/integrative-therapy.html\" rel=\"nofollow noreferrer\">integrative approaches to therapy</a>.</p>\n\n<p>CBT is an integrative model of approach and we had to look at how an integrative approach may be used to support the client within a case study provided.</p>\n\n<hr>\n\n<h3>Case study provided</h3>\n\n<p>Hassan has been referred to you for work-related stress and anxiety. He has a management position and is finding it difficult to cope. At present the information you have is that he is a 42 years old Muslim man, married with 2 children. He has lived in the UK since the age of 5 when his parents travelled here. His father died two years later and Hassan, as the eldest son, has felt responsible for the wellbeing of his mother and sisters as well as his own family.</p>\n\n<p>Your referral is through an employee assistance scheme. Hassan’s assessment shows high level of anxiety without depression. He is otherwise fit and healthy. You may offer him six sessions with a further six sessions if appropriate.</p>\n\n<hr>\n\n<p>An article (<a href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1071164\" rel=\"nofollow noreferrer\">Dhami &amp; Sheikh, 2000</a>) adapted from a chapter in <em>Caring for Muslim Patients</em>, published by Radcliffe Medical Press, Oxford, England; provides key insights needed to allow Muslim clients' concerns to be adequately heard. The vignettes section of the article gives a few sayings of Muhammad regarding relationships with parents and one of them points out that you should “strive to serve them”.</p>\n\n<p>If the client has had the opportunity to fully integrate with the western culture they are living in, they may be more open to challenging their thoughts and beliefs, however we need to be mindful that as therapists, just like we are not here to judge, for an example, on sexuality (<a href=\"https://pinktherapyblog.com/2016/02/17/why-i-am-resigning-from-the-british-association-for-counselling-and-psychotherapy/\" rel=\"nofollow noreferrer\">Pink Therapy, 2016</a>) (<a href=\"https://www.psychotherapy.org.uk/wp-content/uploads/2016/09/Memorandum-of-understanding-on-conversion-therapy.pdf\" rel=\"nofollow noreferrer\">UKCP, 2015</a>), we are not in a position to judge whether a cultural or religious belief is right or wrong, especially when we are not priests, vicars, rabbis, imams or the like. Not only that, if the client is devout in their religious beliefs, then we are not going to change those beliefs very easily, if at all. (<a href=\"http://churchandstate.org.uk/2015/10/the-problem-with-faith-11-ways-religion-is-destroying-humanity/\" rel=\"nofollow noreferrer\">Babilonia, 2015</a>)</p>\n\n<p>The only time when we can intervene in any religious or cultural beliefs is when it is believed that laws may be broken such as the FGM Act (<a href=\"https://www.gov.uk/government/publications/mandatory-reporting-of-female-genital-mutilation-procedural-information\" rel=\"nofollow noreferrer\">Home Office, 2016</a>) (<a href=\"http://www.cps.gov.uk/legal/d_to_g/female_genital_mutilation/#a02\" rel=\"nofollow noreferrer\">Crown Prosecution Service, n.d.</a>), in which case, we would refer the legal case to the necessary authorities and it would be down to the legal profession and not the therapist.</p>\n\n<h3>Strengths and Limitations of integrative approaches to counselling</h3>\n\n<p><strong>Strengths</strong></p>\n\n<p>Integrative counselling and psychotherapy can be seen as one of the most effective approaches within counselling. (<a href=\"http://www.counselling-directory.org.uk/counsellor-articles/integrative-psychotherapy-is-the-best-approach\" rel=\"nofollow noreferrer\">The Counselling Directory, 2013</a>) The idea behind the integrative approach is that no single approach suits every client and therefore you use different approaches and models of therapy to suit the situation and client. The article within The Counselling Directory cited also states that integrative therapy has four different categories:</p>\n\n<ul>\n<li><strong>common factors</strong><br>Looking at the common tools available in each approach that can be useful in the therapy. Therapist/Client rapport, therapist qualities – <a href=\"https://en.wikipedia.org/wiki/Unconditional_positive_regard\" rel=\"nofollow noreferrer\">positive regard</a>, and <a href=\"https://en.wikipedia.org/wiki/Carl_Rogers#Incongruence\" rel=\"nofollow noreferrer\">congruence</a> etc. – emotional release, and clarification etc.</li>\n<li><strong>technical eclecticism</strong><br>The therapist looks at and selects the best interventions by relying on experience and knowledge of what has worked in the past for others, through theories and research literature.</li>\n<li><strong>theoretical integration</strong><br>The combination of two approaches with a common philosophy. The combined ideas are theoretically the same as each other. For example, cognitive behavioural therapy (CBT) is part of the theoretical integration category, as it is a combination of behaviourism and behaviour therapy, and cognitive theories and their application in therapeutic settings (Reeves, 2013), plus, cognitive analytical therapy is also a theoretical integration of psychodynamic therapy and cognitive therapy.</li>\n<li><strong>assimilative integration</strong><br>The therapist primarily sticks to one therapeutic approach, for example Humanistic or psychodynamic, but the therapist will use strategies and models from other therapeutic approaches as well. The combination of ideas will assimilate the pure form of the primary therapeutic approach.</li>\n</ul>\n\n<p><strong>Limitations</strong></p>\n\n<p>The limitations of any integrative therapy depend on the category of integration.</p>\n\n<p><strong><em>Theoretical integration</em></strong></p>\n\n<p>One problem identified in theoretical integration is that it is difficult to integrate some theories; for example, it is difficult to integrate psychodynamic theory and behavioural theory. The psychodynamic approach suggests that our early experiences from birth onwards and their impacts lead to our psychological problems, where behaviour theory sees problems as much more agreeable to change (Reeves, 2013). These differences result in incompatibilities between these theories.</p>\n\n<p><strong><em>Assimilative integration</em></strong></p>\n\n<p>With this kind of integration, there is no balance compared to the other forms of integration. Where the therapist is primarily psychodynamic or humanistic, for example, they will pick and choose ideas from other approaches which may not be put forward by their primary approach, but can work very effectively and contribute to the treatment or treatment plan.</p>\n\n<p><strong><em>Technical eclecticism</em></strong></p>\n\n<p>This shares similarities and differences with assimilative integration, but it has no theoretical underpinning to the approach. (<a href=\"http://www.counselling-directory.org.uk/counsellor-articles/integrative-psychotherapy-is-the-best-approach\" rel=\"nofollow noreferrer\">The Counselling Directory, 2013</a>)</p>\n\n<p>As CBT is a theoretical integrative model, and it is difficult to integrate some theories, CBT cannot and does not incorporate any psychodynamic theories. However, if you are going to work in a fully integrative manner, you need to bear in mind the theories within the psychodynamic approach too. If therapy seems to need some psychodynamic interventions, then you may need to drop CBT sessions sometimes and concentrate on the psychodynamic interventions, maybe through Cognitive Analytical Therapy instead, before continuing with CBT.</p>\n\n<h3>The basic concept of CBT</h3>\n\n<p>Cognitive Behavioural Therapy (CBT) was developed by <a href=\"https://en.wikipedia.org/wiki/Aaron_T._Beck\" rel=\"nofollow noreferrer\">Aaron Temkin Beck</a>, and as mentioned before, CBT is a combination of behaviourism and behaviour therapy, and cognitive theories and their application in therapeutic settings (Reeves, 2013). CBT helps to change how you think, hence the word <em>Cognitive</em>, and what you do, hence the word <em>Behaviour</em>.</p>\n\n<p>A difficult life situation, relationship or practical problem can lead to:</p>\n\n<ul>\n<li>Altered thinking</li>\n<li>Altered emotions and feelings</li>\n<li>Altered behaviour</li>\n<li>Altered physical feelings or symptoms</li>\n</ul>\n\n<p>Things can happen the other way too. Any of the above alterations can lead to a difficult life situation, relationship or practical problem (<a href=\"https://www.rcpsych.ac.uk/healthadvice/treatmentswellbeing/cbt/5areas.aspx\" rel=\"nofollow noreferrer\">Royal College of Psychiatrists, n.d.</a>).</p>\n\n<p>CBT works by trying to get the client to think about a situation in a more helpful way in order to move forward using more helpful behaviours.</p>\n\n<h3>The basic concept of REBT</h3>\n\n<p>Rational Emotive Behaviour Therapy (REBT) has generally been put under the same umbrella as CBT, however although it has similarities, REBT is different. Where CBT was developed by <a href=\"https://en.wikipedia.org/wiki/Aaron_T._Beck\" rel=\"nofollow noreferrer\">Aaron Beck</a>, REBT was developed by <a href=\"https://en.wikipedia.org/wiki/Albert_Ellis\" rel=\"nofollow noreferrer\">Albert Ellis</a> when he started to lose faith in the type of psychoanalysis he was using.</p>\n\n<p>REBT is a practical and action-led model of therapy and personal growth. It doesn’t just focus on the client’s behaviours, but also allows the client to understand the behaviours of others and provide techniques that will help to solve future problems.</p>\n\n<p>Although REBT looks primarily at our current beliefs and behaviours, it also looks at the cause and effect of past experiences and beliefs which create our present beliefs and behaviours. It does this whilst aiming to change irrational beliefs into rational ones quickly rather than slowly, however, one key point to note is that the therapist does not impose rational beliefs on the client, but accepts there are non-rational beliefs that may help people achieve happiness. That way, the therapist is accepting the client’s value system.</p>\n\n<p>REBT, uses an A-B-C-D-E formula.</p>\n\n<ul>\n<li><strong>A</strong>ctivating Experience<br>Also referred to by some as the Initial Sensitising Event (ISE), this is the root cause of our unhappiness</li>\n<li><strong>B</strong>eliefs<br>Irrational self-defeating beliefs that are the source of our unhappiness, or come about as a result of the ISE</li>\n<li><strong>C</strong>onsequences<br>The neurotic symptoms and negative feelings and emotions that result from the ISE and/or Beliefs</li>\n<li><strong>D</strong>ispute<br>We must dispute and challenge these irrational beliefs in order for the client to enjoy a balanced outlook in life</li>\n<li><strong>E</strong>ffects<br>The client must learn to enjoy the effects of the new rational beliefs and get used to the changes, letting them become the new norm.</li>\n</ul>\n\n<h3>The shortfalls of CBT</h3>\n\n<p>As mentioned before, One of the ideas put forward about CBT is that it is a suitable form of therapy for all human problems. This idea can be damaging in some respects, as CBT is not suitable for all psychological conditions.</p>\n\n<p>Interestingly, whilst researching the overall efficacy of CBT, I came across a few items of note.</p>\n\n<ul>\n<li>Carl Rogers emphasised the quality of the therapeutic relationship as a necessary and sufficient condition for successful therapy (<a href=\"http://www.shoreline.edu/dchris/psych236/Documents/Rogers.pdf\" rel=\"nofollow noreferrer\">Rogers, 1957</a>) whereas CBT therapists tend to see the alliance as more instrumental in ensuring the patient’s adherence to the treatment protocol (e.g. <a href=\"https://doi.org/10.1002/cpp.481\" rel=\"nofollow noreferrer\">Dunn, et al., 2006</a>) (<a href=\"https://doi.org/10.1017/S003329171500032X\" rel=\"nofollow noreferrer\">Goldsmith, et al., 2015</a>)</li>\n<li>The Countess of Mar in the House of Lords suggested the results of a trial into the effectiveness of CBT and GET (graded exercise therapy) had been artificially inflated (BACP, 2013)</li>\n<li>An international team of researchers (<a href=\"https://doi.org/10.1002/wps.20346\" rel=\"nofollow noreferrer\">Cuijpers, et al., 2016</a>) concludes that<br>\n\n<blockquote>\n <p>…CBT is ‘probably effective’ with major depression, general anxiety disorder, panic disorder and social anxiety disorder, but not as effective as has been claimed, due to publication bias, poor quality of studies, and the use of waiting list control groups as a comparator. (BACP, 2016)</p>\n</blockquote></li>\n<li>CBT is as much based on the development of a therapeutic alliance as it is in a psychodynamic and humanistic approach. The success of therapy will be, at least partly, informed by the nature of the therapeutic process, and not simply the application of particular theoretical ideas, as some suggest (Reeves, 2013)</li>\n<li>Recent literature provides fairly strong evidence that CBT in addition to antipsychotic medication is effective in the management of acute as well as chronic schizophrenia (<a href=\"https://doi.org/10.1097/00001504-200503000-00009\" rel=\"nofollow noreferrer\">Rathod &amp; Turkington, 2005</a>). However, I would stress that CBT was not used alone in any of these studies from what I have seen. It was used carefully in conjunction with psychiatric help and antipsychotic medication.</li>\n</ul>\n\n<p>An alternative to CBT called Metacognitive Therapy (MCT) has been touted to be better than CBT. But it was developed by Manchester University (<a href=\"https://medicalxpress.com/news/2020-05-therapy-effective-cognitive-behavioral-depression.html\" rel=\"nofollow noreferrer\">Addelman, 2020</a>) and studied by Manchester University (<a href=\"https://doi.org/10.3389/fpsyg.2019.02621\" rel=\"nofollow noreferrer\">Wells, 2019</a>) so more independent studies are needed.</p>\n\n<p>Either way, if the client is not able or willing to challenge their thoughts and behaviours, then CBT will not be effective.</p>\n\n<hr>\n\n<h2>References</h2>\n\n<p>Addelman, M.

Rather, the causes involve auditory brain regions beyond the inner ear, likely due to those circuits no longer receiving the input they used to receive after damage to the cochlea.</p>\n\n<p>Hearing damage in certain frequencies both kills the hair cells (causing deafness) and also induces tinnitus. Therefore, deafness as a cure for tinnitus seems not only undesirable but quite counterproductive in those cases.</p>\n\n<p>In contrast, cochlear implants have in some cases reduced tinnitus, and this is effectively the opposite solution: restoring some version of lost hearing, rather than removing what remains.</p>\n\n<p><strong>Deafening can be a cure for peripheral (originating in the ear) tinnitus</strong></p>\n\n<p>Some forms of tinnitus seem to have a peripheral origin. For example, tinnitus may occur when there is a selective loss of outer but not inner hair cells in a region of the cochlea. In this context, lesioning those inner hair cells could possibly solve the problem, while also deafening the patient at those frequencies. I am unaware, however, of a surgical procedure that can successfully produce such a selective lesion (please comment if anyone knows differently).</p>\n\n<p>Curing tinnitus by lesioning the auditory nerve (thereby deafening the patient) <em>can</em> cure tinnitus in some patients.

Can induced deafness cure tinnitus
[ "hearing", "ear", "tinnitus", "cure", "deaf" ]
<p>Some forms of tinnitus are caused by damage to the microscopic hairs in the inner ear, that, once damaged, can send electrical signals that cause the ringing sound. So wouldn't that mean that just eliminating the hairs entirely would cure the tinnitus? Deafness would be caused but some people would likely find living with no sound at all more preferable to constant ringing.</p>

[ { "answer_id": 16331, "body": "<p>The relationship between thyroid function and body weight is bidirectional and complex. </p>\n\n<p>It is known for decades, if not centuries, that cretinism (only in the end of the 19th century to be associated to hypothyroidism) may be accompanied by weight gain and that thyrotoxicosis may result in weight loss. As early as in 1835 Robert J. Graves described that ladies affected by goitre and palpitations (probably due to hyperthyroidism resulting from the disease which is now named after him) were remarkably thin [2]. Five years later the German physician Karl von Basedow described the same condition, where a lady suffering from goitre, Exophthalmos and palpitations had severely emaciated [3]. In 1883 the swiss surgeon Theodor Kocher described weight gain after total thyroidectomy [4]. Ten years later, in 1893 William Ord described rapid weight loss, after myxoedematous patients were set on treatment with thyroid extreact [5].</p>\n\n<p>Today it is known that over one third of hypothyroid infants have a birth weight greater than the ninetieth percentile [6, 7]. However, an “atypical” form of hypothyroidism may be associated to low birth weight [8]. Of course, weight gain in hypothyroidism isn’t restricted to infants, but common in adults, too. Hypothyroidism is assumed to contribute 2.5 to 5 kg (5 to 10 pounds) to body weight [9]. </p>\n\n<p>On the other hand, changes in body weight may also result in changes of thyroid function. A number of studies, as recently extensively reviewed [10, 11], described elevated TSH levels and increased total step-up deiodinase activity in patients with weight gain. These changes were reversible after weight loss [12]. On the other hand, low T3 syndrome is a well-known consequence of anorexia and starvation [13, 14].</p>\n\n<p>Probably, these changes represent adaptive responses of pituitary-thyroid axis to type 1 or type 2 allostasis, respectively [15]. The observed mechanisms may contribute to some kind of autoregulation of weight in conditions of changing supply with energy.</p>\n\n<p><a href=\"https://i.stack.imgur.com/oTLCo.jpg\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/oTLCo.jpg\" alt=\"Autoregulation of weight in obesity [Chatzitomaris et al. 2017, CC BY license]\"></a></p>\n\n<p>To use thyroid hormones as an adjunct treatment in obesity is strongly discouraged, since cardiovascular side effects may be significant [16].</p>\n\n<p><strong>References</strong></p>\n\n<p>1: <a href=\"https://www.frontiersin.org/articles/10.3389/fendo.2017.00163/full\" rel=\"noreferrer\">https://www.frontiersin.org/articles/10.3389/fendo.2017.00163/full</a></p>\n\n<p>2: Graves RT.

Abnormal thyroid function and obesity - known links?
[ "weight", "thyroid" ]
<p>In conversations regarding the increasing number of people that are obese (in an American or European context), often times claims regarding thyroid function being a significant contributor to these developments come up. I've tried finding sources written by medical experts addressing a lay audience to clarify these issues, but I can't find anything that makes the issue clear enough for me.</p> <p>Question(s): </p> <ul> <li><p>Is there a known causal relationship that goes "abnormal thyroid function -> higher weight"? I don't know whether thyroid issues develop later in life or are congenital, or how much of an impact they have, so this question might be ill-phrased.</p></li> <li><p>If abnormal thyroid function is known to have effects on weight gain, can we quantify how many people are affected by this, and how much weight gain per person is caused by this?</p></li> <li><p>Are there thyroid conditions that make it extremely difficult not to put on weight (say, you continue to put on weight despite eating less than 1000 calories a day), and if so, do we know how many people are affected by those conditions?</p></li> </ul>

[ { "answer_id": 16484, "body": "<p>This is a good question, and although as you correctly state that HIV is an STI (see <a href=\"https://health.stackexchange.com/a/16502\">STI vs STD vs Sexually Transmitted Virus?</a>) there is a difference with HIV which is one reason why it may be separated from others.</p>\n\n<p>It can be thought that HIV is separated from STIs in factsheet titles etc. because HIV is a virus when others are not, but there are other STI viruses. For example, there is:</p>\n\n<ul>\n<li><a href=\"https://www.nhs.uk/chq/Pages/2611.aspx\" rel=\"nofollow noreferrer\">Human Papilloma Virus (HPV)</a>, which is the name for a group of viruses that affect your skin and the moist membranes lining your body.</li>\n<li><a href=\"https://www.cdc.gov/std/herpes/stdfact-herpes-detailed.htm\" rel=\"nofollow noreferrer\">Herpes</a>, which is caused by the herpes simplex virus type 1 (HSV-1) or type 2 (HSV-2).</li>\n</ul>\n\n<p>It can also be thought that HIV is separated from STIs in factsheet titles etc. because HIV can be fatal, but there are other STIs which can lead to death. For example:</p>\n\n<ul>\n<li><a href=\"https://www.cdc.gov/std/syphilis/stdfact-syphilis-detailed.htm\" rel=\"nofollow noreferrer\">Syphilis</a> can affect multiple organ systems, including the brain, nerves, eyes, liver, heart, and blood vessels. The effects on the heart can lead to death.</li>\n<li><a href=\"https://www.cdc.gov/std/gonorrhea/stdfact-gonorrhea-detailed.htm\" rel=\"nofollow noreferrer\">Gonorrhea</a> can also spread to the blood and cause disseminated gonococcal infection (DGI). DGI is usually characterized by arthritis, tenosynovitis, and/or dermatitis. This condition can be life threatening.</li>\n<li><a href=\"https://www.cdc.gov/std/hpv/stdfact-hpv.htm\" rel=\"nofollow noreferrer\">HPV (Human Papillomavirus)</a> can cause cervical and other cancers including cancer of the vulva, vagina, penis, or anus. It can also cause cancer in the back of the throat, including the base of the tongue and tonsils (called oropharyngeal cancer).</li>\n</ul>\n\n<h2>Possible reasons for separating HIV from other STIs in factsheets</h2>\n\n<ol>\n<li>The key thing with HIV is that <strong>apart from <a href=\"https://www.cdc.gov/hepatitis\" rel=\"nofollow noreferrer\">Hepatitis</a></strong>, which is also viral, all other STIs are generally only transmittable only through sexual contact. HIV can be transmitted through infected blood transfusions, use of infected needles, or through contact between <strong>broken skin</strong> of 2 or more people.</li>\n</ol>\n\n<p><strong>Note: Skin to skin contact with unbroken skin is safe</strong></p>\n\n<ol start=\"2\">\n<li><p>STIs are infections and STDs are the diseases as a result of the infection. Some STDs don't share the same name as the STI which caused it.</p></li>\n<li><p>(This applies to your question) The linked factsheets etc. you provided are talking about the links between HIV and other STIs.</p></li>\n</ol>\n\n<h2>How reason 3 applies here</h2>\n\n<p>Reading the <a href=\"https://www.cdc.gov/std/hiv/stdfact-std-hiv-detailed.htm\" rel=\"nofollow noreferrer\">detailed version of the CDC factsheet on HIV and STDs</a>:</p>\n\n<blockquote>\n <p>[P]eople who get syphilis, gonorrhea, and herpes often also have HIV or are <strong>more likely to get HIV</strong> in the future. One reason is the behaviors that put someone at risk for one infection (not using condoms, multiple partners, anonymous partners) often put them at risk for other infections. Also, because STD and HIV tend to be linked, when someone gets an STD it suggests they got it from someone who may be at risk for other STD and HIV. Finally, a sore or inflammation from an STD may allow infection with HIV that would have been stopped by intact skin.</p>\n</blockquote>\n\n<p>Another interesting fact is that studies that have lowered the risk of STD in communities have not necessarily lowered the risk of HIV. Risk of HIV was lowered in one community trial (<a href=\"https://doi.org/10.1016/S0140-6736(95)91380-7\" rel=\"nofollow noreferrer\">Grosskurth, et al. 1995</a>), but not in 3 others (<a href=\"https://doi.org/10.1016/S0140-6736(98)06439-3\" rel=\"nofollow noreferrer\">Wawer, et al., 1999</a>; <a href=\"https://doi.org/10.1016/S0140-6736(03)12598-6\" rel=\"nofollow noreferrer\">Kamali, et al., 2003</a>; <a href=\"https://doi.org/10.1371/journal.pmed.0040102\" rel=\"nofollow noreferrer\">Gregson, et al., 2007</a>).</p>\n\n<p>Also, treating individuals for STDs has not necessarily lowered their risk of acquiring HIV (<a href=\"https://journals.lww.com/aidsonline/Fulltext/2001/07270/Effect_of_interventions_to_control_sexually.12.aspx\" rel=\"nofollow noreferrer\">Ghys, et al., 2001</a>; <a href=\"https://doi.org/10.1001/jama.291.21.2555\" rel=\"nofollow noreferrer\">Kaul, et al., 2004</a>).</p>\n\n<h2>Further Reading</h2>\n\n<p><a href=\"https://www.nhs.uk/chq/Pages/2611.aspx\" rel=\"nofollow noreferrer\">What is HPV?</a> — NHS<br>\n<a href=\"https://www.cdc.gov/std/hpv/stdfact-hpv.htm\" rel=\"nofollow noreferrer\">Genital HPV Infection Fact Sheet</a> — CDC</p>\n\n<p><a href=\"https://www.cdc.gov/hepatitis\" rel=\"nofollow noreferrer\">Hepatatis Factsheets</a> - CDC</p>\n\n<p><a href=\"https://www.cdc.gov/std/herpes/stdfact-herpes-detailed.htm\" rel=\"nofollow noreferrer\">Genital Herpes Fact Sheet</a> - CDC</p>\n\n<h2>References</h2>\n\n<p>Ghys, P.

It's more about how the authors decide to title their articles.</p>\n\n<hr>\n\n<p>Explanation of the terms used to prevent confusion:</p>\n\n<p><strong>HIV</strong> refers to either the human immunodeficiency <em>virus</em> or, when this enters the body, to <em>HIV infection,</em> which is a sexually transmitted <em>infection</em> (STI). HIV infection becomes a sexually transmitted <em>disease</em> (STD), namely <strong>AIDS,</strong> only when it causes damage to the body and, usually, symptoms.

HIV is a virus that once it is in your body and you have antibodies developed will have caused an STI, which once it progresses to the symptoms of AIDS, becomes an STD that nobody wants.</p>\n\n<p>So it is mainly a historically formed cultural response to single out HIV. And a result of attention marketing.</p>\n\n<p>HIV spread very rapidly in the West from the late 70s onwards, it was seen as an incurable deadly disease – that was new, and initially not even widely recognised as an STD, but sometimes as God's revenge, a form of cancer etc. –that just takes long enough to kill everyone infected to enable all those promiscuous sinners to infect a large number of people.<br>\n<sub>(<a href=\"https://www.cambridge.org/core/books/the-origins-of-aids/2BDB50F42C4E17103286A3043647AA4D\" rel=\"nofollow noreferrer\">Jaques Pepin: \"The Origins of AIDS\", Cambridge University Press: Cambridge, New York, 2011,</a> ch 13 Globalisation.)</sub></p>\n\n<p>At the time of identification the public mind just had a lot of sex from the sexual revolution and saw other STDs as a souvenir from being very active, to be worn in pride since antibiotics could cure the most prominent bacterial infections with unprecedented effectiveness. This carefree and wrong attitude towards many STDs is still somewhat prevalent. </p>\n\n<blockquote>\n <p>The advent of the gay liberation movement in the late 1960s and 1970s led to the creation of a more self-confident ‘out’ gay community with a number of activist and campaigning groups. Sexual liberation became an important component of gay life; many sexually active gay men came to regard attendance at STD clinics as a regular, if inconvenient, aspect of sexual life.<br>\n By the mid-1960s, the number of attendances at STD clinics was increasing dramatically. The ‘sexual revolution’ of the ‘permissive society’, the advent of the oral contraceptive pill and the declining popularity of the condom all contributed to an increase of STDs, particularly viral infections. The increased incidence of STDs was seen in official circles as ‘primarily a reflection of sexual promiscuity in the population’; rather than prostitutes, however, the main social groups now seen to be responsible were teenagers, immigrants, asymptomatic promiscuous women and homosexuals.<br>\n <sub>(<a href=\"http://www.history.ac.uk/reviews/review/248\" rel=\"nofollow noreferrer\">Roger Davidson and Lesley A. Hall (Eds.)</a>: \"Sex, Sin and Suffering.\n Venereal disease and European society since 1870\", Routledge: London, New York, 2001, p 246–247.)</sub></p>\n</blockquote>\n\n<p>In the case of HIV/AIDS these social background factors of scientific medicine still linger on:</p>\n\n<blockquote>\n <p>Scientific discoveries such as the discovery of a new disease exert a fascination not only on the scientific community and the lay public, but also on social scientists. For the first, discovery is the main drive and the ultimate goal. For the lay public, it is often accompanied by the promise of curing illnesses and improving people’s lives. For social scientists, scientific discoveries are the domain where the role, influence, and limitations of social factors – such as interests, resources, and relationships – can be perhaps best examined.<br>\n That such factors play a role in discovery making has not been contested; the question is whether scientific discoveries are evaluated, acknowledged, and accepted by the scientific community according to universal standards of rationality or according to the resources, influence, and social relationships of the scientists themselves. The positivist tradition has solved this problem by distinguishing between the context of discovery and the context of justification. Whereas the former is messy (involving serendipity, accident, resources, interests, and the like), the latter is determined by rigorous criteria of universal applicability.<br>\n This distinction has been contested by sociologists and historians of science alike who argue that, in practice, the two contexts are indistinguishable: justification takes place in the process of discovery itself (e.g., Nickles 1992, p. 89; Hacking 1996, p. 51). Consequently, justification is not exclusively determined by logical criteria; factors such as interests, resources, and networks of relationships play a considerable role (Stump 1996, p. 445). </p>\n \n <p><sub><a href=\"http://www.cambridge.org/core_title/gb/245053\" rel=\"nofollow noreferrer\">Alex Preda: \"AIDS, Rhetoric, and Medical Knowledge\", Cambridge University Press: Cambridge, New York, 2005</a>, p47. </sub></p>\n</blockquote>\n\n<p>\"Getting AIDS\" is still seen by the larger public as the most dangerous of all STDs, with most others either classified as manageable or less important in their consequences. Whether true or not is irrelevant in the public's mind, and even these attitudes seem in decline and attention is unhealthily highly put on AIDS/HIV treatment advances, \"normal lives\", and now even the possibilities of vaccinations getting closer.</p>\n\n<p>If this reason for keeping HIV singled out when talking about STI/STDs is historical, why keep it separate? </p>\n\n<p>On the one hand, there is this connection between other STDs and HIV/AIDS, mentioned in other answers: having one increases to chance of catching the other. But it is also theorised that from a public health standpoint awareness and acceptance of preventive measures, testing and treatments might be improved simultaneously – not to mention the all important funding of research, prevention programs – the hypothesis of \"epidemiological synergy (<a href=\"https://www.ncbi.nlm.nih.gov/pubmed/1595015\" rel=\"nofollow noreferrer\">Wasserheit 1992</a>; <a href=\"https://www.ncbi.nlm.nih.gov/pubmed/10448335\" rel=\"nofollow noreferrer\">Fleming and Wasserheit 1999</a>).\"</p>\n\n<blockquote>\n <p><sub>Charles Klein &amp; Delia Easton: \"Structural Barriers and Facilitators in HIV Prevention: A Review of International Research\"; Sevgi O.

Peterman: \"STD Diagnosis and Treatment as an HIV Prevention Strategy\"; in: <a href=\"https://www.springer.com/us/book/9780306467318\" rel=\"nofollow noreferrer\">Ann O’Leary (Ed.): \"Beyond Condoms. Alternative Approaches to HIV Prevention\", Kluwer Academic Publishers: New York, Boston, 2002</a>.)</sub><br>\n STD control for HIV prevention is a controversial interface between well-financed HIV prevention programs and less wealthy STD prevention programs. STD experts are frustrated at the lack of HIV and other resources committed to this HIV prevention strategy. Some HIV experts are skeptical of the motivations of the proponents of this strategy, and think the potential for HIV prevention by STD control has been exaggerated. Between these two camps lies a huge mass of data accumulated by hundreds of studies conducted over the past 15 years. Synthesizing this data is particularly important for HIV prevention world wide, because the developing countries where STD control programs have been weak are often the countries where the AIDS epidemic has been most devastating.\n While epidemiological and microbiological evidence support the existence of a two-way relationship between STDs and HIV infection, the relationship between early and appropriate diagnosis and treatment of STDs and prevention of spread of HIV needs to be further elaborated. The parameters that need to be specified in such elaboration include 1) factors related to the STI: the specific STI; whether the STI is symptomatic or asymptomatic; whether the STI is incident (new) infection or prevalent (chronic or long standing) infection; and perhaps the stage of the sexually transmitted infection; 2) factors related to the population, which may also function as multipliers of the STI effect: age-gender composition; patterns of sexual mixing and concurrency; prevalence of male circumcision; 3) factors related to the phases of the STD and HIV epidemics: for example, whether the HIV and STD epidemics are nascent or generalized epidemics; 4) factors related to the goals of the HIV prevention program: objectives related topreventing the acquisition of infection among the uninfected; objectives related to preventing the transmission of infection by the infected; objectives related to provision of services to protect the personal health of individual members of the population; objectives related to protecting public health, i.e., limiting the spread of HIV infections: objectives related to targeting primary prevention of HIV through behavior change versus primary prevention of HIV through control of co-factors. The appropriate approach to the implementation of STD control for HIV prevention in a specific setting depends on the values of all of the above factors. In addition, many of the above factors are interdependent, and it is important to consider their reciprocal influences.</p>\n</blockquote>\n\n<p>It seems quite useful from an epidemiological view to just not neglect one of the two closely interconnected halves of this problem realm. And previously, after the advent of penicillin, the public mind and imaginations (including those of politicians) did start to neglect other STDs as long as the discussion went for funding, morals and opinions were always cheap. </p>\n\n<blockquote>\n <p>From this perspective, rhetorical practices are not an obstacle but rather a necessary ingredient of expert democracy. Bridging the gap between science and the general public has become crucial to the public sphere and democracy. This means we must acknowledge that rhetorical practices do matter and act accordingly.<br>\n <sub>Preda (2005): \"How Rhetorical Practices Matter for AIDS Prevention\", p229ff.</sub></p>\n</blockquote>\n\n<hr>\n\n<p>To sum this position up: HIV/AIDS was seen as something different from what was known as STI/STDs even by medical professionals, it is still seen as \"different\" in the public eye. Apart from being \"on of the most <a href=\"http://www.enjoyliving.at/lieben-und-leben-magazin/lust-und-liebe/sexualitaet/haeufige-geschlechtskrankheiten-ein-ueberblick.html\" rel=\"nofollow noreferrer\">\"popular\" STIs</a> it is also seen as the deadliest. Apart from the historical reasons that lead to it being listed separately, this separation is continued for science communication reasons. It is thought to help with awareness, prevention, testing and treatment. In really short terms: sticklers, like me, point out quite rightly that HIV/AIDS is an STI/STD. But the usual presentation now is both historically grown <em>and</em> useful. </p>\n", "score": 2 } ]

However, one strategy to improve treatment adherence that is both simple, inexpensive and supported by peer-reviewed empirical evidence is the use of a pillbox.</p>\n<p>The following relates to the use of pillboxes with respect to compliance with HART medications:</p>\n<blockquote>\n<p><strong><a href=\"https://doi.org/10.1086/521250\" rel=\"nofollow noreferrer\">Pillbox Organizers are Associated with Improved Adherence to HIV Antiretroviral Therapy and Viral Suppression: a Marginal Structural Model Analysis</a></strong></p>\n<p>Background.

Data were obtained from an observational cohort of 245 human immunodeficiency virus (HIV)–infected subjects who were observed from 1996 through 2000 in San Francisco, California. Adherence was the primary outcome and was measured using unannounced monthly pill counts. Plasma HIV RNA level was considered as a secondary outcome. Marginal structural models were used to estimate the effect of pillbox organizer use on adherence and viral suppression, adjusting for confounding by CD4+ T cell count, viral load, prior adherence, recreational drug use, demographic characteristics, and current and past treatment.</p>\n<p>Results. Pillbox organizer use was estimated to improve adherence by 4.1%–4.5% and was associated with a decrease in viral load of 0.34–0.37 log10 copies/mL and a 14.2%–15.7% higher probability of achieving a viral load ⩽400 copies/mL (odds ratio, 1.8–1.9).

Eligible participants were aged 18 to 64 years and taking 1 to 3 oral medications for long-term use. Participants had to be suboptimally adherent to all of their prescribed therapies (with a medication possession ratio of 30% to 80%) in the 12 months before randomization.

In each stratum, randomization occurred within blocks defined by whether all of the patient's targeted medications were dosed once daily. Patients were randomized to receive in the mail a pill bottle strip with toggles, digital timer cap, or standard pillbox. The control group received neither notification nor a device. Data were collected from February 12, 2013, through March 21, 2015, and data analyses were on the intention-to-treat population.</p>\n<p>Main Outcomes and Measures: The primary outcome was optimal adherence (medication possession ratio ≥80%) to all eligible medications among patients in the chronic disease stratum during 12 months of follow-up, ascertained using pharmacy claims data. Secondary outcomes included optimal adherence to cardiovascular medications among patients in the chronic disease stratum as well as optimal adherence to antidepressants.</p>\n<p>Results: Of the 53 480 participants, mean (SD) age was 45 (12) years and 56% were female. In the primary analysis, 15.5% of patients in the chronic disease stratum assigned to the standard pillbox, 15.1% assigned to the digital timer cap, 16.3% assigned to the pill bottle strip with toggles, and 15.1% assigned to the control arm were optimally adherent to their prescribed treatments during follow-up.

In this review, we will examine the following: 1) the ontogeny of the active immune response and the ability of neonates and young infants to respond to vaccines; 2) the theoretic capacity of an infant’s immune system; 3) data that demonstrate that mild or moderate illness does not interfere with an infant’s ability to generate protective immune responses to vaccines; 4) how infants respond to vaccines given in combination compared with the same vaccines given separately; 5) data showing that vaccinated children are not more likely to develop infections with other pathogens than unvaccinated children; and 6) the fact that infants actually encounter fewer antigens in vaccines today than they did 40 or 100 years ago.</p>\n</blockquote>\n\n<p>In summary, they said</p>\n\n<blockquote>\n <p>Current studies do not support the hypothesis that multiple vaccines overwhelm, weaken, or “use up” the immune system.

If vaccines cause a weakened immune system, then we would expect to see a higher incidence of illness following vaccination. In that study conducted in Israel, the incidence of acute illnesses in the 30 day period following DTP vaccine was compared to the incidence in the same children for the 30 day period prior to vaccine. The three-day period immediately following vaccine was excluded because children frequently develop fever as a direct response to vaccine toxins.

BUT because anxiety might be a symptom of a medical condition, it's important to see a doctor to be formally diagnosed, and receive individualized treatment recommendations.</em></p>\n\n<p>Generalized anxiety disorder is, at its root, over-activity of the sympathetic nervous system. It is when the normal human \"fight or flight\" response is extended and/or exaggerated. Panic attacks occur when that gets stuck in a positive feedback loop. </p>\n\n<p>Physical symptoms of anxiety or panic are due to this sympathetic hyper-activation: increased heart rate, blood pressure, respirations, alertness, sensory awareness (including pain), sweating, speed of reaction, gastrointestinal upset, etc. It helps to understand that anxiety and panic disorders develop more frequently in people who have experienced severe traumatic stressors, especially during childhood, during which their neurological system becomes conditioned to overreact. During \"fight or flight\" much of our mental processing gets caught up in the limbic system (center of emotion) rather than engaging the frontal cortex (center of logical reasoning), which is why anxiety can impair clarity of thought, decision-making, and memory.</p>\n\n<p>Deep breathing, mediation, and certain biofeedback techniques can activate the parasympathetic nervous system, thereby decreasing sympathetic tone.

NMN also enhances hepatic insulin sensitivity and restores gene expression related to oxidative stress, inflammatory response, and circadian rhythm, partly through SIRT1 activation.

The same mice given low doses of streptozotocin are a model of type 2 diabetes (T2D), developing hyperglycemia, severe insulin resistance and diabetic peripheral neuropathy involving sensory and motor neurons. Because of suggestions that increased NAD+ metabolism might address glycemic control and be neuroprotective, we treated prediabetic and T2D mice with nicotinamide riboside (NR) added to HFD. NR improved glucose tolerance, reduced weight gain, liver damage and the development of hepatic steatosis in prediabetic mice while protecting against sensory neuropathy. In T2D mice, NR greatly reduced non-fasting and fasting blood glucose, weight gain and hepatic steatosis while protecting against diabetic neuropathy. The neuroprotective effect of NR could not be explained by glycemic control alone. Corneal confocal microscopy was the most sensitive measure of neurodegeneration. This assay allowed detection of the protective effect of NR on small nerve structures in living mice. Quantitative metabolomics established that hepatic NADP+ and NADPH levels were significantly degraded in prediabetes and T2D but were largely protected when mice were supplemented with NR. The data justify testing of NR in human models of obesity, T2D and associated neuropathies.</p>\n</blockquote></li>\n<li><p>Article: <a href=\"http://herbnutritionals.com/nutraceuticals/nicotinamide-mononucleotide-nmn\" rel=\"nofollow noreferrer\">What is nicotinamide mononucleotide?</a></p></li>\n<li><p>Forum: <a href=\"https://www.longecity.org/forum/topic/97853-new-study-on-nr-vs-diabetic-neuropathy/\" rel=\"nofollow noreferrer\">New Study on NR vs. Diabetic Neuropathy</a></p></li>\n</ul>\n", "score": 3 }, { "answer_id": 19000, "body": "<p>Yes, there is a cure.</p>\n\n<p>It won't be 100% effective for all diabetics to completely forgo all of their medication, but around 80% of diabetics will be able to go off all of their medication.</p>\n\n<p>This is one of many articles that address this particular topic: <a href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1325029/\" rel=\"nofollow noreferrer\">https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1325029/</a></p>\n\n<p>In short, the cause of insulin resistance is chronic over consumption of high carbohydrate diets, and particularly high fructose diets.</p>\n\n<p>This may be a little extreme a perspective for those with a more orthodox view of nutrition, but bare with me. <em>Carbohydrates in excess</em> is toxic to the liver and other organs, in a similar way that alcohol is.

<p>For individuals with heavy flow, menstruation can be extremely taxing. </p> <p>Are there ways of managing duration and heaviness of the menstruation? I know that ibuprofen is prescribed, but how about other medication?</p> <p>If there's a finite amount of tissue to shed within the uterus, then it would seem that speeding up the sloughing or shedding process would reduce the menstruation period. But I am not sure how hormones play a role in this and if they purely dictate the process or if perhaps the hormones respond to the uterine waste that needs to be removed.

If avoiding lactose alleviates your symptoms, you've potentially treated your primary lactose intolerance successfully. If you feel somewhat better but still experience classic GI problems (bloating, diarrhea), you might be lactose intolerant secondary to a <a href=\"http://www.airitilibrary.com/Publication/alDetailedMesh?DocID=09647058-201512-201512310024-201512310024-s9-s13\" rel=\"noreferrer\">different illness</a> like Crohn's disease or celiac disease. Keep in mind, lactose intolerance is caused by the lack of an enzyme (lactase) in your body, so lactose can't be digested – a milk allergy is your body generating an immune response to certain milk proteins, but doesn't suggest any enzymatic deficit.</p>\n\n<p>Usually, your physician will perform a <a href=\"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4175689/#Sec3title\" rel=\"noreferrer\">hydrogen breath test</a> to confirm a lactose intolerance diagnosis. When you're missing the lactase enzyme, you can't digest lactose (which means you can't absorb lactose, since it's \"too big\" pre-digestion – this and energy release are the goals of catabolism). This results in lactose sitting around post-consumption (there are no enzymes available to cleave it for transport), where it starts to ferment in your gut microbiota. Bacterial digestion like this makes degradation products like methane, carbon dioxide, and <em>hydrogen</em> (this is where the name \"hydrogen breath test\" comes from), and we can measure these gases as they rise to escape from your GI tract. A basic schematic:</p>\n\n<p><a href=\"https://i.stack.imgur.com/y1OIx.jpg\" rel=\"noreferrer\"><img src=\"https://i.stack.imgur.com/y1OIx.jpg\" alt=\"Hydrogen breath test\"></a></p>\n\n<p>Some people <a href=\"http://iopscience.iop.org/article/10.1088/1752-7155/7/2/024001/meta\" rel=\"noreferrer\">don't exhibit conventional responses</a> to the hydrogen breath test, so a methane breath test or combination test might be more reliable. Alternatively, <a href=\"https://www.tandfonline.com/doi/abs/10.3109/00365529409091742\" rel=\"noreferrer\">fecal pH tests</a> can be used to show GI irregularities like lactose intolerance (malabsorption makes your stool acidic). More invasive techniques like <a href=\"https://www.ncbi.nlm.nih.gov/pubmed/1173735\" rel=\"noreferrer\">blood glucose monitoring</a> or even <a href=\"http://pediatrics.aappublications.org/content/118/3/1279.short\" rel=\"noreferrer\">intestinal biopsy for disaccharidase quantitation</a> can be employed, although the general patient population is well-suited for noninvasive tests like those that require only spent breath or stool and pH paper.</p>\n", "score": 6 } ]
