title: Effect of dietery weight loss on sex steroid binding sex steroids, and gonadotropins in obese postmenopausal women.
abstract: Measurements of SSBG, E2, T, and gonadotropins were performed in 12 obese postmenopausal women before, during, and after a supplemented fast. Weight loss (mean 18 kg) was associated with an increase in SSBG to levels above those seen in nonobese postmenopausal women, a decrease in serum E2 levels, unchanged T levels, and an increase in both gonadotropins. Thus we conclude that weight change or the circumstances associated with it lead to alterations in circulating levels of SSBG. These observations are consistent with the presence of elevated free T and possibly higher free E2 levels in obese postmenopausal women.
