title: [Evaluation of beta-endorphin levels and gonadotropin, prolactin, cortisol and estradiol in serum of girls with secondary amenorrhea associated with weight loss].
abstract: Levels of beta-endorphin, FSH, LH, PRL, cortisol and estradiol in blood serum were measured in 20 girls with weight loss related amenorrhoea. Serum beta-endorphin levels were also measured in a group of 15 young, regularly menstruating healthy girls (control group). Levels of beta-endorphin were significantly lower in examined group than in control one. Serum levels of FSH, LH, estradiol were low. Serum levels of PRL and cortisol were normal. These observations suggest, that beta-endorphin is involved in the pathogenesis of weight loss related amenorrhoea.
