Obesity occurs in 60% of women after menopause and is characterized by an excess of adipose tissue that depends on several orexigenic (neuropeptide Y (NPY) stimulates carbohydrate ingestion, galanin stimulates fat intake) and anorectic (leptin, cholecystokinin (CCK)) factors

We investigated basal levels of serum leptin, CCK, galanin and NPY in 16 non-obese premenopausal women, in 15 obese premenopausal women (body mass index (BMI) 34.6 +/- 1.3 SD) and in ten obese postmenopausal women (BMI 34.7 +/- 1.5 SD) to determine the relationship between obesity, menopause and these neuropeptides

Significantly increased leptin and galanin levels in postmenopausal obese women coupled with decreased NPY levels revealed some changes in the neuropeptides regulating eating behavior, which may be the reason for the onset of postmenopausal obesity
