Gastric inhibitory polypeptide (GIP) is a hormone produced by the intestinal K-cells that regulates insulin secretion and glucose metabolism. As a technical term, GIP is not widely used in everyday communication, which means that it might be useful to have more synonyms for the word to help make it more accessible. Some synonyms for GIP might include "glucose-dependent insulinotropic polypeptide," "incretin hormone," "intestinal hormone," or simply "insulin-regulating hormone." Each of these terms refers to the same hormone but can help provide a more varied vocabulary for discussing the complex processes involved in glucose and insulin regulation.
