What Is Wegovy?
Wegovy® is the brand name for semaglutide, a type of medication known as a GLP-1 receptor agonist. It is designed to help with long-term weight management in adults who are either:
- Living with obesity (Body Mass Index of 30 or above), or
- Overweight (BMI of 27.5 or above) with at least one weight-related health condition, such as type 2 diabetes, high blood pressure, or high cholesterol.
In Singapore, Wegovy is only available with a doctor’s prescription and must be part of a comprehensive weight management plan that includes healthy eating and regular physical activity.
How Does Wegovy Work?
Wegovy works by mimicking a natural hormone called GLP-1 (glucagon-like peptide-1). GLP-1 plays a role in regulating appetite and food intake. It works by:
- Slowing gastric emptying – helping you feel full for longer after eating.
- Acting on appetite centres in the brain – reducing hunger and food cravings.
- Supporting lower calorie intake – making it easier to achieve and maintain a calorie deficit.
Wegovy is administered once a week using a pre-filled injection pen. The dose is gradually increased over several weeks to improve tolerability and minimise side effects.
Are There Risks And Side Effects?
Like all prescription medications, Wegovy carries potential risks. Common side Wegovy effects include:
- Nausea
- Vomiting
- Diarrhoea or constipation
- Abdominal discomfort
These symptoms are often temporary and will improve as your body adapts. Rare but more serious risks include pancreatitis, gallbladder disease, and possible thyroid tumours.
Your doctor will monitor your progress, side effects, and overall health while you are on treatment.

Wegovy is not suitable for people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 (MEN 2).
What Is The Estimated Cost Of Wegovy In Singapore
The cost of Wegovy in Singapore varies depending on the clinic. Patients can expect prices starting from around S$400–S$500 per dose for the medication alone. The final cost will depend on number of dosages required, doctor consultation fees, and any accompanying weight-management services provided by the clinic.
Wegovy Vs Other Weight-Loss Treatments
In Singapore, other medically approved weight-loss treatments include:
- Orlistat (Xenical®) – an oral medication that reduces fat absorption from food.
- Liraglutide (Saxenda®) – a daily GLP-1 injection with similar appetite-suppressing effects, but requiring more frequent dosing than Wegovy®.
- Bariatric surgery – such as gastric bypass or sleeve gastrectomy, recommended for severe obesity when other options have failed.
Compared to daily injections, Wegovy’s once-weekly dosing may be more convenient. Compared to orlistat, Wegovy® tends to produce greater average weight loss but requires injections instead of pills.
When Wegovy May Not Be Effective
Wegovy is not a “magic solution” and will not work effectively without lifestyle changes. It may also be less effective if:
- The recommended diet and physical activity plan is not followed.
- The dose is not taken consistently.
- The patient has underlying health issues, such as unmanaged hormonal conditions, that are not addressed.
Additionally, weight loss results vary between individuals. Some people may experience only modest reductions despite full compliance. In such cases, your doctor may adjust the dose, suggest switching to an alternative medication, or consider other treatment options.
