Glucagon-like peptide-1 (GLP-1) is a hormone produced in the intestines that plays a crucial role in regulating blood sugar levels. It is released after eating and helps stimulate insulin secretion from the pancreas, which lowers blood sugar. GLP-1 also slows down gastric emptying, making you feel full longer, and reduces appetite. In addition to its effects on blood sugar, GLP-1 has been studied for its potential benefits in treating type 2 diabetes and obesity. Medications that mimic GLP-1, known as GLP-1 receptor agonists, are used to help manage these conditions by enhancing the body's natural response to food intake.
