title: Hormonal circadian rhythms in eating disorders.
abstract: The circadian rhythm of several plasma hormones (prolactin, growth hormone, adrenocorticotropic hormone (ACTH), cortisol, and melatonin) was simultaneously evaluated in 23 women with anorexia nervosa (AN), in 27 obese (OB) women, and in gender and age-matched healthy controls. A trend toward similar alterations of the circadian pattern of the different hormones was observed in the two groups of patients, with the exception of plasma growth hormone (GH), which exhibited nutrition-dependent impairments. The timing of the peaks for each hormonal rhythm revealed the existence of an internal desynchronization in both eating disorders.
