In recent years, Wegovy has become a global sensation for its ability to support sustainable weight loss in individuals struggling with obesity or type 2 diabetes. Now available in Thailand, Wegovy offers hope for those who have tried diet and exercise alone—without long-term success.
In this guide, we’ll explore how Wegovy works, who it’s suitable for, where to get it in Thailand, and what to expect on your journey toward better health.
What Is Wegovy?
Wegovy is an FDA-approved once-weekly injection that contains semaglutide, a medication originally used to manage type 2 diabetes. It belongs to a class of drugs called GLP-1 receptor agonists (glucagon-like peptide-1), which mimic the natural hormone that helps regulate blood sugar and appetite.
While semaglutide was first used in diabetes medications like Ozempic, higher doses have shown remarkable effects in weight loss, leading to the development of Wegovy specifically for obesity management.
How Does Wegovy Work?
Wegovy (semaglutide) works through multiple mechanisms:
- Suppresses appetite by acting on the brain’s hunger centers
- Slows gastric emptying, making you feel full longer
- Regulates insulin and glucagon to stabilize blood sugar
- Reduces food cravings, particularly for high-fat or high-sugar foods
With consistent weekly use, it supports gradual and lasting weight reduction, particularly when combined with healthy lifestyle changes.
Who Can Use Wegovy?
Wegovy is generally prescribed for adults who meet one of the following:
- Have a BMI ≥ 30 (classified as obese)
- Have a BMI ≥ 27 and also suffer from weight-related conditions such as high blood pressure, type 2 diabetes, or high cholesterol
It’s important to consult with a doctor for a full health evaluation before beginning treatment, as Wegovy is a prescription-only medication.
Wegovy in Thailand: What You Need to Know
Wegovy is now available at licensed clinics in Thailand, especially in Bangkok, Phuket, and other major cities. Clinics that offer GLP-1 therapy will usually provide:
- Doctor consultation
- Health screening (BMI, blood tests, etc.)
- A personalized dosage plan
- Follow-up monitoring
- Lifestyle counseling
OpenHouse Clinic, located in Silom, Bangkok, is one such provider offering Wegovy and other metabolic treatments under physician supervision.
How to Use Wegovy: Injection & Dosage
Wegovy is administered via a subcutaneous injection (under the skin), usually in the thigh, abdomen, or upper arm. The pen is easy to use and comes pre-filled.
Typical dosage schedule:
| Weeks | Dose |
|---|---|
| 1–4 | 0.25 mg weekly |
| 5–8 | 0.5 mg weekly |
| 9–12 | 1.0 mg weekly |
| 13+ | 1.7–2.4 mg weekly (maintenance dose) |
Dosage is gradually increased to minimize side effects such as nausea or stomach upset.
Common Side Effects
Most users tolerate Wegovy well, especially with dose titration. However, some may experience:
- Nausea
- Constipation or diarrhea
- Headache
- Fatigue
- Abdominal discomfort
These effects typically subside after the body adjusts. Always follow your doctor’s advice on managing symptoms.
How Much Does Wegovy Cost in Thailand?
The cost of Wegovy in Thailand varies by clinic and dose strength, but prices typically range from:
- THB 4,900–9,000 per pen, depending on brand, dose, and consultation package
- Some clinics offer monthly or 3-month programs with nutritional guidance included
Ask for packages that include follow-ups and lifestyle support for the best results.
