Weight loss is thought to be caused by bariatric surgery due to gastric restriction, intestinal malabsorption, or both. Adjustable gastric banding (AGB) and other restrictive surgeries limit functional stomach capacity and delay gastric emptying. Biliopancreatic diversion (BPD) is a malabsorptive operation that leaves the stomach mostly intact but diverts ingested food to the ileum, leaving just a tiny part of the colon to absorb nutrients. The usual proximal Roux-en-Y gastric bypass (RYGB) combines gastric restriction with nutritional bypass of the majority of the stomach and a short segment of the proximal intestine (mainly the duodenum); the small bowel remaining is adequate to prevent clinically severe malabsorption. Weight loss is caused by stomach constriction, as well as other mechanisms such as changes in gut hormones and other processes that are still being studied (4–1.. Read More»
