Background: The impact of pre-surgical binge eating on postoperative outcomes is poorly understood. Previous studies have found marked preoperative differences between binge eaters (BE) and non-binge eaters (NBE) in hunger and disinhibition using the Three-Factor Eating Questionnaire (TFEQ). Short-term prospective data are mixed regarding whether these differences persist after surgery and if preoperative binge eating impacts postoperative weight outcomes. The purpose of the present study was to compare self-reported eating behavior and weight outcomes between BE and NBE after the first postoperative year. Methods: Prior to surgery, 72 Roux-en-Y gastric bypass (RYGBP) patients completed the Questionnaire of Eating and Weight Patterns (QEWP) or QEWP-Revised (QEWP-R), to assess binge eating status which was defined as one objective binge episode per week over the past 6 months. Subjects also completed the TFEQ prior to surgery and again ≥12 months after surgery. Results: For BE, higher scores were found for both hunger and disinhibition prior to surgery. At a mean of 18 months after surgery, BE and NBE were indistinguishable on these subscales and there were no differences in weight lost. Conclusions: RYGBP surgery has an equally positive impact on eating behavior and weight loss for both BE and NBE. Within a multidisciplinary clinic, preoperative BE status does not appear to be a negative prognostic indicator for RYGBP surgery in the domains of weight loss and disinhibition. Further replication is needed with longer follow-up times and larger samples.
