Plasma Concentrations of Fibroblast Growth Factors 19 and 21 in Patients with Anorexia Nervosa

Abstract

Circulating levels of FGF21 but not FGF19 are strongly related to body weight and serum levels of leptin, adiponectin, and insulin in both anorectic and normal-weight women. We suggest that reduced plasma FGF21 levels could be involved in the pathophysiology of AN or in a complex adaptive response to this disease.
