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. In addition to its effects on insulin, GLP-1 can reduce appetite and promote weight loss. Due to these properties, GLP-1 analogs are used in medications for managing type 2 diabetes and obesity, helping improve glycemic control and support weight management.
