The impacts of eating disorders on sleeve gastrectomy outcomes
Abstract
Introduction: Eating disorders have been found to be associated with poorer weight loss outcomes following sleeve gastrectomy. However, limited research has been conducted on the specific impact of eating disorders on patients after sleeve gastrectomy. This study aimed to investigate the role of eating disorders, particularly binge eating disorder and loss of control, on weight loss outcomes and eating-disorder psychopathology following sleeve gastrectomy. Methods: A prospective study was conducted on 104 individuals who underwent sleeve gastrectomy and reported experiencing eating disorders at least once weekly. Eating disorders were assessed using the Eating Disorder Examination (EDE) Bariatric Surgery Version. Chi-square and ANOVA tests were used for categorical and dimensional variables, respectively. Results: Of the participants, 55 cases (52.88%) were diagnosed with binge eating disorder and 49 cases (47.11%) were categorized as having loss of control. The group with binge eating disorder had significantly greater EDE scores and lower weight loss outcomes compared to the loss of control group at six months post-surgery. Conclusion: Our findings suggest that binge eating disorder is associated with poorer outcomes following sleeve gastrectomy, including greater severity of eating-disorder psychopathology and poorer weight loss outcomes. The results of this study highlight the need for additional research on the specific impacts of eating disorders on patients undergoing sleeve gastrectomy. The possible limitations of this study are self-reported eating disorders, lack of a control group, and short-term follow-up.
