Impaired secretion of glucagon-like peptide 1 (GLP-1) has been suggested to contribute to the deficient incretin effect in patients with type 2 diabetes. It is unclear whether this is a primary defect or a consequence of the hyperglycemia in type 2 diabetes. We examined whether acute hyperglycemia reduces the postprandial excursions of gastric inhibitory polypeptide (GIP) and GLP-1, and if so, whether this can be attributed to changes in gastric emptying.
