Rapid gastric and intestinal transit is a major determinant of changes in blood glucose, intestinal hormones, glucose absorption and postprandial symptoms after gastric bypass

Abstract

After RYGB, reducing intestinal glucose delivery to 4 kcal/min is associated with higher blood glucose, greater glucose absorption, lower incretin responses, and less GI symptoms, supporting rapid transit contribution to the exaggerated incretin responses and "dumping symptoms".
