Background: Incretin Hormones
GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and glucagon are three peptide hormones that play central roles in metabolic regulation. They are secreted in response to nutrient ingestion and act on receptors throughout the body to regulate insulin secretion, gastric emptying, appetite, and energy expenditure.
The incretin effect — the enhanced insulin response to oral versus intravenous glucose — is mediated primarily by GLP-1 and GIP. Research into these pathways has driven some of the most significant advances in metabolic medicine over the past two decades.
