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\u2010en\u2010Y 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\u2010increases were noted, short to medium\u2010term reductions after RYGB were common, and reported changes after AGB were inconsistent. Short to medium\u2010term reductions in emotional eating, and from a few studies, short to long\u2010term 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\u2010quality evidence. Long\u2010term 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\u2010term improvement of any problematic or disordered eating behaviours.<\/jats:p>","DOI":"10.1111\/obr.12425","type":"journal-article","created":{"date-parts":[[2016,6,14]],"date-time":"2016-06-14T08:27:28Z","timestamp":1465892848000},"page":"770-792","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":65,"title":["Changes
