## What are GLP-1 Agonists?
GLP-1 (Glucagon-Like Peptide-1) agonists are medications that mimic the body's natural GLP-1 hormone, which plays a key role in blood sugar regulation and appetite control.
## Semaglutide vs Tirzepatide
### Semaglutide
- Weekly injection
- GLP-1 receptor agonist
- Clinically proven for significant weight loss
- Also improves cardiovascular markers
### Tirzepatide
- Weekly injection
- Dual GIP/GLP-1 receptor agonist
- May produce even greater weight loss results
- Also improves blood sugar control
## Dosing Protocols
Both medications follow a gradual dose escalation schedule to minimize side effects. Your clinician will create a personalized plan based on your health profile.
## Managing Side Effects
- Start with smaller meals
- Stay hydrated
- Eat slowly and mindfully
- Common initial effects (nausea) typically improve over 2-4 weeks
## Lifestyle Integration
GLP-1 medications work best when combined with:
- Regular physical activity
- Balanced nutrition
