In order to investigate changes in endocrine function, various tests were performed on eleven patients with anorexia nervosa. In two of them, endocrine function before and after treatment was also studied.<BR>The responses of plasma LH and FSH to LH-RH were decreased in the patients as were plasma LH-RH, and LH and FSH responses to the oral administration of clomiphene citrate. In more than half of the cases, plasma TSH showed a delayed response to TRH. The basal levels of plasma GH were elevated, and plasma GH responses to hypoglycemia or 1-arginine were lowered in half of the patients. Plasma GH showed a paradoxical rise after glucose load in three out of six cases. Plasma IRI responses to 1-arginine load were decreased in some cases, but plasma IRG responses to 1-arginine were rather excessive. Plasma IRI after glucose load showed low or delayed responses in most of the cases. After the body weight was increased to normal levels by the treatment, pituitary and pancreatic endocrine functions were normalized.<BR>These findings indicate that hypothalamic function is primarily impaired in this disease and causes nutritional disorder followed by the dysfunction of some endocrine organs. Such a possibility could be supported by the improvement of endocrine function after body weight has been recovered.
