How Weight Loss Injections Work
Mechanism of Weight Loss Injection
You may wonder what happens in your body with weight loss injections. These treatments change how your body deals with hunger, fat, and energy. When you get a weekly shot, your body reacts in different ways. Here is what happens:
1. Appetite Reduction: The injection turns on GLP-1 receptors in your brain. You feel less hungry and eat less.
2. Slower Digestion: Your stomach takes longer to empty. You stay full for more time and your blood sugar stays steady.
3. Improved Blood Sugar Control: The injection helps your body make insulin. Your blood sugar stays balanced.
4. Enhanced Fat Breakdown: Ingredients like methionine and inositol help your liver break down fat better.
5. Boosted Energy Levels: B vitamins in some injections help you feel less tired. You can be more active.
6. Liver Support for Metabolism: Your liver gets extra help, so your metabolism works better. You keep a healthy balance between fat and muscle.
You get a non-surgical treatment for obesity that targets the main reasons for weight gain. These injections use special bioactive compounds to help you lose fat and keep your energy up.
Injectable weight-loss medicines are actually diabetes medicines used in a new way. Doctors have used this GLP-1 group for type 2 diabetes for a long time. This hormone comes from your small intestine and tells you to stop eating. The difference is your gut makes GLP-1 for only a few minutes. When it stops, you do not feel full anymore. With a GLP-1 injection, the new ones last a whole week. So, all day and night, you feel like you just ate.
See how these injections change your hormones and metabolism:
Hormone/Pathway | Effect of Weight Loss Injections |
GLP-1 | Acts like incretin hormone, changes appetite, turns on anorexigenic neurons, helps you feel full, lowers hunger. |
Insulin | Raises insulin release when glucose is high. |
Glucagon | Lowers glucagon release, so your liver makes less sugar. |
Gastric Emptying | Slows down stomach emptying, so you feel full longer after eating. |
