Eighteen morbidly obese women had plasma brain-derived neurotrophic factor (BDNF) measured before bariatric surgery and 3 months postoperatively. We analyzed plasma BDNF levels in all the participants then subdivided according to menopausal status and type of surgery. Brain-derived neurotrophic factor decreased significantly in all the participants and in the premenopausal group when looked at in isolation.
