Psychosocial outcome of gastric bypass surgery for patients with and without binge eating.

Background: There is limited data on the prevalence of eating disorder pathology in morbidly obese patients undergoing Roux-en-Y gastric bypass (RYGBP) and the degree to which this may affect surgical outcome. The present study examined surgical outcome between 2 groups of patients undergoing RYGBP: those with pre-surgical binge eating (BE) and those without pre-surgical binge eating (NBE).

Methods: This study tested the hypothesis that the BE group would demonstrate greater pathology on measures of eating pathology, psychological wellbeing, and quality of life than the NBE group both pre- and post-surgery.
