Weight Loss Injections: Uses, Benefits, Side Effects & What to Know
Wegovy and other prescription weight loss injections are medications designed to help individuals manage obesity or excess body weight alongside a healthy diet and regular physical activity.
These medications are commonly prescribed for:
- Obesity management
- Weight-related medical conditions
- Appetite control
- Long-term weight management support
Some injectable medications are also used for type 2 diabetes treatment but may additionally support weight loss under medical supervision.
How Weight Loss Injections Work
Many modern weight loss injections work by mimicking hormones involved in appetite and blood sugar regulation.
GLP-1 Receptor Agonists
Some medications mimic GLP-1 (glucagon-like peptide-1), a hormone that helps:
- Reduce appetite
- Slow stomach emptying
- Improve feelings of fullness
- Support blood sugar regulation
This can help reduce calorie intake and support gradual weight reduction.
According to the U.S. Food and Drug Administration (FDA), prescription weight management medications should only be used under medical supervision and alongside lifestyle modifications.
Common Types of Weight Loss Injections
1. Semaglutide Injections
Examples include:
- Wegovy
- Ozempic (used primarily for diabetes but sometimes discussed in weight management contexts)
2. Tirzepatide Injections
Examples include:

- Mounjaro
These medications work on multiple hormone pathways related to appetite and metabolism.
