GLP-1, or glucagon-like peptide-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, which lowers blood sugar. Additionally, GLP-1 slows down gastric emptying, making you feel fuller for longer, and reduces appetite. GLP-1 is also a target for certain diabetes medications, known as GLP-1 receptor agonists. These drugs mimic the effects of the hormone, helping people with type 2 diabetes manage their blood sugar levels more effectively. They can also aid in weight loss, making them beneficial for many patients.
