Changes in problematic and disordered eating after gastric bypass, adjustable gastric banding and vertical sleeve gastrectomy: a systematic review of pre-post studies.
Despite differences in their mechanisms and outcomes, little is known about whether postsurgical changes in eating behaviours also differ by bariatric procedure. Following a systematic search, 23 studies on changes in binge eating disorder (BED) and related behaviours, bulimia nervosa and related behaviours, night eating syndrome, grazing and emotional eating after Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB) and vertical sleeve gastrectomy (VSG) were reviewed. Significant methodological problems and a dearth of literature regarding many behaviours and VSG were seen. Regarding BED and related behaviours, although later re-increases were noted, short to medium-term reductions after RYGB were common, and reported changes after AGB were inconsistent. Short to medium-term reductions in emotional eating, and from a few studies, short to long-term reductions in bulimic symptoms, were reported after RYGB. Reoccurrences and new occurrences of problem and disordered eating, especially BED and binge episodes, were apparent after RYGB and AGB. Further conclusions and comparisons could not be made because of limited or low-quality evidence. Long-term comparison studies of changes to problematic and disordered eating in RYGB, AGB and VSG patients are needed. It is currently unclear whether any bariatric procedure leads to long-term improvement of any problematic or disordered eating behaviours.
