Women with PCOS are more prone to obesity which exacerbates insulin resistance, the abdominal fat disposition and metabolic risk of these patients. With development of obesity these women have high conversion rate from normal glucose tolerance to impaired glucose tolerance and in turn to type 2 diabetes.

Glucagon-like peptide 1 (GLP-1) is involved in body weight maintenance. Beside energy balance it is also involved in glucose homeostasis. Functional deficit in GLP-1 facilitates obesity. We investigated the link between the concentration of incretin hormones and glucose homeostasis, metabolic complications and the distribution of body composition in obese women with PCOS.
