Return of Menses in Previously Overweight Patients with Eating Disorders.

Previously overweight patients with eating disorders present differently than their normal weight peers, so reliance on weight status as a screening criteria may result in underdiagnosis. Though BMI z-scores associated with menses resumption are higher for previously overweight patients, there is no difference in weight gain between presentation and menses resumption and time to menses resumption compared to previously normal weight patients. Moreover, menses resumption occurred at weights significantly lower than premorbid maximum weight for previously overweight patients, so restoration to highest premorbid weight is not necessary.
