Gastric inhibitory polypeptide (GIP), also known as glucose-dependent insulinotropic polypeptide, is an inhibiting hormone of the secretin family of hormones.^[5] While it is a weak inhibitor of gastric acid secretion, its main role, being an incretin, is to stimulate insulin secretion.^[6]

GIP, along with glucagon-like peptide-1 (GLP-1), belongs to a class of molecules referred to as incretins,^[7] which stimulate insulin release on oral food intake.
