What Are GLP-1 Medications?
GLP-1 (Glucagon-Like Peptide-1) medications are a class of drugs that mimic a hormone naturally produced in your intestines. Originally developed to treat type 2 diabetes, researchers discovered these medications had a remarkable side effect: significant weight loss in many patients.
How GLP-1 Works in Your Body
When you eat, your intestines naturally release GLP-1 hormone, which performs several important functions:
- Slows gastric emptying: Food stays in your stomach longer, helping you feel full
- Reduces appetite: Signals to your brain that you're satisfied
- Regulates blood sugar: Helps your pancreas release appropriate amounts of insulin
- Decreases food cravings: Particularly for high-calorie, processed foods
GLP-1 weight loss treatments essentially amplify these natural processes, making it easier to maintain a caloric deficit necessary for weight loss.
