GASTRIC BYPASS SURGERY HAS GREATER EFFECT THAN CALORIE RESTRICTION ON INCRETIN RELEASE AND INSULIN SECRETION ALREADY ON POSTOP. DAY 1
Background: Gastric bypass surgery (GBP) provokes rapid improvement of type 2 diabetes (T2D) prior to significant weight loss. Thishas been attributed to altered secretion of the two incretin hormones glucagon-like peptide 1 (GLP-1) and glucose-dependentinsulinotropic polypeptide (GIP). Here we studied the effects of very low calorie diet (VLCD) vs. the immediate effects of GBP onglycaemia and inc
