Bowel Habits After Bariatric Surgery

Abstract

The type of bariatric surgery affects bowel habits in an operation-specific manner, resulting mainly in diarrhea after BPD and RYGB, and constipation after AGB. Flatulence severity impairs quality of life most in BPD, is intermediate in RYGB, and is only minor after AGB, a phenomenon that was only partially mirrored in quality-of-life measures of BAROS.

Ten-year changes in health-related quality of life after biliopancreatic diversion with duodenal switch

“…However, the differences in SF-36 scores may be related to factors such as redundant skin, change in bowel habits, fear of weight regain or losing control over food or overeating [28][29][30].…”

Practical Recommendations of the Obesity Management Task Force of the European Association for the Study of Obesity for the Post-Bariatric Surgery Medical Management

“…Diarrhoea and Steatorrhoea: Disordered bowel habits are frequent after malabsorptive bariatric surgery, and patients undergoing biliopancreatic diversion or duodenal switch frequently reported intestinal symptoms that may impair quality of life or interfere with social functioning (increased number of bowel movements with loose stools or diarrhoea, faecal urgency, abdominal bloating and smelling flatulence) [13]. These symptoms are related to fat and carbohydrate malabsorption and to bacterial overgrowth.…”

Bileopancreatic Diversion with Duodenal Switch Lowers Both Early and Late Phases of Glucose, Insulin and Proinsulin Responses After Meal

“…BPD-DS patients more frequently develop diarrhoea and flatulence compared with RYGBP patients [27]. Similarly, jejuno-ileal bypass patients develop steatorrhoea [28] and BPD without DS surgery induces markedly limited fat absorption [29].…”
