How Do GLP-1 Agonists Work?
GLP-1 is a natural hormone that your small intestine makes. It helps keep your blood sugar at a good level. GLP-1 medicines work like this hormone in your body. They slow down gastric emptying. This lets food move slower from the stomach to the small intestine, just like what the natural hormone does.
GLP-1 work by:
- Making Insulin Come From Your Pancreas – Insulin is a hormone that helps your body use sugar from what you eat as energy. If you do not have enough insulin, your blood sugar goes up. This can lead to diabetes.
- Stopping Glucagon Secretion – The glucagon hormone gives your body a boost in blood sugar when you need it. GLP-1 drugs work to make sure your body does not put too much glucose in your blood. They also help control how the glucagon works to keep blood sugar levels steady.
- Making Food Move Slower in Your Stomach – These drugs slow how fast food leaves the stomach. This makes your body soak up sugar from food more slowly. It helps keep blood sugar levels stable and can help you feel full for longer.
- Cutting Down Your Hunger – GLP-1 works on parts of your brain that manage hunger and being full. You feel less hungry and have fewer cravings. It helps with weight loss.
The GLP-1 drug can help you control your blood sugar. It also helps lower your food intake. This makes you feel less hungry and want less food. Using this drug can help you keep your weight under control.
