Semaglutide is a drug molecule that mimics GLP-1, a naturally occurring hormone in the human body, and has 94% sequence homology with the latter. GLP-1 is one of many hormones released by the small intestine after people eat. It can promote the secretion of insulin when it acts on the pancreas, slow down gastric emptying when it acts on the digestive tract, and produce a feeling of fullness when it acts on the hypothalamus. Therefore, drugs that mimic GLP-1 (such as semaglutide) can activate GLP-1 receptors in the human body, which not only regulates blood sugar and treats diabetes, but also slows digestion and suppresses appetite. Not only that, semaglutide is more stable than GLP-1 in the human body
