Fast pouch emptying, delayed small intestinal transit, and exaggerated gut hormone responses after Roux‐en‐Y gastric bypass

Abstract

After RYGB, the bulk of foods pass without hindrance into the small intestine, while the small intestinal transit is prolonged. The rapid exposure of the gut epithelium contributes to the exaggerated release of GLP-1 and PYY3-36 after RYGB.
