Abstract

In health, postprandial glycemic excursions are attenuated via stimulation of insulin secretion, suppression of glucagon secretion, and slowing of gastric emptying. The incretin hormones, glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide, are primary modulators of this response. Drugs have recently been developed that exploit the incretin-axis for the management of type 2 diabetes. There is burgeoning interest in the potential of incretin therapies for the management of acute hyperglycemia in the critically ill. This article outlines basic incretin physiology, highlights relevant pharmacology, and briefly summarizes the literature on incretins for glycemic control in t..
