What is the Meaning of Incretin System?

The Incretin System is a crucial component of glucose homeostasis, comprising a group of gut-derived hormones released into the circulation shortly after the ingestion of nutrients. The two most significant incretin hormones are Glucagon-like Peptide-1 (GLP-1) and Glucose-dependent Insulinotropic Polypeptide (GIP). This system acts physiologically to potentiate glucose-stimulated insulin secretion from the pancreatic beta cells, thereby playing a vital role in the meticulous regulation of postprandial blood sugar levels. Its function is a major pharmacological target in the clinical management of Type 2 Diabetes Mellitus.

What is the Origin of Incretin System?

The term "incretin" is a portmanteau derived from the concepts of "intestine secretion insulin," accurately reflecting the origin and primary action of these hormones. The system's existence was initially hypothesized based on the observation that oral glucose administration elicited a significantly greater insulin response compared to intravenous glucose infusion. This discovery, known as the incretin effect, highlighted the direct and essential role of the gut in the endocrine regulation of systemic metabolism.

What is the Mechanism of Incretin System?

The ingestion of food triggers the rapid release of GLP-1 and GIP from enteroendocrine cells located in the small intestine. These hormones travel through the bloodstream to the pancreas, where they bind to specific receptors on the beta cells. This binding enhances the release of insulin in a strictly glucose-dependent manner, a feature that inherently minimizes the risk of severe hypoglycemia. Additionally, GLP-1 acts centrally to promote satiety and peripherally to slow gastric emptying, further contributing to overall metabolic control.
