ClinConnect Summary

Following a meal, gut-produced incretin hormones such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are released into the circulation. GLP-1 and GIP, the two dominant incretin hormones, are part of a natural endogenous system involved in maintaining glucose homeostasis. In the presence of normal or elevated, but not low, glucose concentration, both GLP-1 and GIP increase insulin secretion from pancreatic islet beta-cells (β-cells). GLP-1 also lowers glucagon secretion from pancreatic alpha-cells and delays nutrient delivery from the stomach by inh...
