What Is Wegovy?
Wegovy is a once-weekly prescription injection containing semaglutide.
Semaglutide belongs to a class of medications called GLP‑1 receptor agonists.
These medications help regulate:
- Appetite
- Satiety
- Blood sugar levels
- Gastric emptying
- Food intake
Many patients experience:
- Reduced appetite
- Lower calorie intake
- Weight reduction
- Improved metabolic regulation
Wegovy is typically prescribed alongside:
- Reduced-calorie diets
- Physical activity
- Long-term lifestyle changes
How Wegovy Works
Semaglutide mimics a natural hormone called GLP‑1 (glucagon-like peptide‑1).
This hormone affects several systems linked to hunger and metabolism.
Main Effects of Wegovy
Appetite Reduction
Many patients naturally eat less because they feel fuller sooner.
Slower Digestion
Food remains in the stomach longer, increasing satiety.
Reduced Food Cravings
Some users report reduced food noise and fewer cravings.
Improved Metabolic Regulation
GLP‑1 medications may improve blood sugar control and metabolic function.
Wegovy Dosage Schedule
Doctors usually increase Wegovy gradually to reduce gastrointestinal side effects.
Standard Wegovy Dosage Chart

| Weeks 1–4 | 0.25 mg |

| Weeks 13–16 | 1.7 mg |
| Maintenance Dose | 2.4 mg |
Patients should follow their doctor’s instructions carefully.

Why Wegovy Dosage Increases Gradually
The gradual dose-escalation process helps the body adapt to semaglutide.
