Wegovy is an FDA-approved prescription medication designed to aid adults with obesity or overweight conditions in managing their weight. It contains semaglutide, a compound that mimics the GLP-1 (glucagon-like peptide-1) hormone—naturally produced in the body—to help regulate appetite, food intake, and metabolism.
Unlike traditional weight loss supplements, Wegovy injection works on a hormonal level, helping you feel full faster and stay full longer. When combined with a healthy diet and regular physical activity, it has shown significant results in clinical studies for long-term weight reduction.
How Does Wegovy Injection Work?
Wegovy functions by mimicking GLP-1, which influences multiple body systems related to hunger and digestion. Here’s how it helps with weight management:
| Mechanism | Effect on Body |
|---|---|
| Appetite suppression | Reduces cravings and hunger signals |
| Delayed gastric emptying | Keeps you feeling full longer |
| Insulin regulation | Helps stabilize blood sugar levels |
| Caloric intake control | Naturally limits overeating |
By targeting the brain’s appetite control center (hypothalamus), Wegovy helps break the cycle of constant hunger and emotional eating.
Who Can Use Wegovy Injection?
Wegovy is prescribed for adults with:
- A Body Mass Index (BMI) ≥ 30 kg/m² (classified as obese)
- A BMI ≥ 27 kg/m² (overweight) with at least one weight-related condition, such as:
- Type 2 diabetes
- High cholesterol
- High blood pressure
It’s not a cosmetic weight loss solution but a medically supervised treatment for chronic weight management.

General Guidelines:
