What Is Wegovy and How Does It Work?
Wegovy (semaglutide) is a GLP-1 receptor agonist approved by the Health Sciences Authority (HSA) in Singapore for chronic weight management. It works by mimicking the naturally occurring GLP-1 hormone, which regulates appetite and food intake.
How Does It Work?
- Appetite suppression: Signals your brain that you are full, reducing hunger
- Slowed gastric emptying: Food stays in your stomach longer, keeping you satisfied
- Improved insulin sensitivity: Better blood sugar control reduces cravings
- Calorie reduction: Patients naturally eat 25-35% fewer calories
Clinical trials published in the New England Journal of Medicine (2021) showed that patients lost an average of 15-20% of their body weight over 68 weeks with Wegovy, compared to 2.5% with placebo.
Wegovy vs Saxenda vs Mounjaro: Key Differences
Several GLP-1 medications are available in Singapore. Each has different efficacy profiles, dosing schedules, and costs. Here is how they compare:
| Medication | Active Ingredient | Average Weight Loss | Dosing Frequency | HSA Approved |
|---|---|---|---|---|
| Wegovy | Semaglutide | 15-20% | Weekly injection | Yes |
| Saxenda | Liraglutide | 5-10% | Daily injection | Yes |
| Mounjaro | Tirzepatide | 20-25% | Weekly injection | Limited |
| Ozempic | Semaglutide | 10-15% | Weekly injection | Yes (diabetes) |
Note: Ozempic is approved for diabetes management. Wegovy is the higher-dose formulation specifically approved for weight loss.
Who Qualifies for Medical Weight Loss?
Medical weight loss with GLP-1 medications is not for everyone. HSA guidelines require:
| Criteria | Requirement |
|---|---|
| BMI ≥ 30 | Obesity classification (no additional conditions needed) |
| BMI ≥ 27 | Overweight with at least one weight-related condition |
| Age | 18 years or older |
| Prior attempts | Documented diet and exercise efforts |
| Medical clearance | No contraindications |
At Accord Medical Clinic, Dr Joseph Wang conducts a thorough assessment to determine if GLP-1 therapy is appropriate for you.
