Prediction of reproductive status in women with bulimia nervosa by past high weight.

It is not understood why disturbed menstrual function occurs in as many as 50% of women with bulimia nervosa who are at normal weight. The authors measured luteinizing hormone (LH), estradiol, and progesterone in 13 women with bulimia nervosa who were at normal weight and six normal comparison subjects. They found that the women with bulimia nervosa were likely to have abnormal 24-hour luteinizing hormone (LH) secretion if their current weight was less than 85% of their past high weight.
