Weight Loss Injection Treatment in Singapore

Introduction

Losing weight can be a challenging journey, and for many people, diet and exercise alone may not deliver significant or sustainable results. Medical weight loss injections—including Semaglutide (Ozempic & Wegovy) and Tirzepatide (Mounjaro)—offer a science-backed solution for individuals struggling with obesity or weight-related conditions such as diabetes, hypertension, and high cholesterol.

This guide explores how these weight loss injections in Singapore work, their benefits, risks, and what patients can expect when undergoing medical weight loss treatment at Bay Medical (Weight Loss Clinic)

What Is Medical Weight Loss?

Medical weight loss refers to treatments supervised by licensed healthcare professionals within a medical clinic. Unlike slimming centres, unproven supplements, or fad diets, medical weight loss uses clinically proven prescription medications to achieve safe, steady, and sustainable weight reduction.

A comprehensive medical weight loss programme typically includes:

  • Medical history review & health screening
  • Prescription medications (e.g weight loss injections such as Wegovy or Mounjaro)
  • Lifestyle guidance (nutrition, activity, sleep, stress)
  • Regular monitoring & follow-up

Medical weight loss is recommended for individuals with:

  • Obesity BMI > 30, or
  • Overweight BMI > 27 with obesity-related conditions (diabetes, hypertension, high cholesterol, osteoarthritis)

Overview of GLP-1 Receptor Agonist Medications aka GLP-1 Weight Loss Injections

GLP-1 receptor agonists mimic a natural hormone called GLP-1, which regulates:

  • Appetite
  • Digestion
  • Blood sugar levels

These medications help reduce hunger, prolong fullness, and improve metabolic health—making weight loss more achievable.

Registered GLP-1 medications in Singapore include:

  • Semaglutide (Ozempic)
  • Semaglutide (Wegovy)
  • Semaglutide (Rybelsus)
  • Tirzepatide (Mounjaro) – dual GLP-1 & GIP receptor action

Ozempic – once weekly Semaglutide Injection in Singapore

Ozempic (semaglutide) was developed for type 2 diabetes but has gained popularity as an off-label weight loss treatment due to its strong appetite-reducing effects.

Ozempic works by:

  • Activating GLP-1 receptors in the brain
  • Suppressing appetite and cravings
  • Slowing gastric emptying
  • Enhancing satiety after meals

Clinical trials show that patients using Ozempic can lose up to 15% of body weight over 12 months when combined with diet and exercise.

Important Note:
Ozempic is approved for diabetes treatment in Singapore. Using Ozempic for weight loss is considered off-label and should only be done under proper medical supervision. Now that Wegovy is available in Singapore, doctors no longer need to prescribe off label Ozempic.

Wegovy – Higher-Dose Semaglutide for Weight Management

Wegovy (semaglutide) is a once weekly semaglutide injection officially approved in Singapore for obesity and medical weight management.

Wegovy vs Ozempic: Wegovy contains a higher dose of Semaglutide than Ozempic, making it more effective for weight loss. Like Ozempic, Wegovy is administered once weekly and works best when combined with healthy lifestyle changes.

Current Singapore Update:
Wegovy is available in Singapore (from ~July 2025).

Tirzepatide Mounjaro Singapore

Tirzepatide (Mounjaro) – Dual GLP-1/GIP Weight Loss Injection

Tirzepatide (Mounjaro) is a injectable medication that targets two hormones instead of one:

  • GLP-1 → reduces appetite
  • GIP → enhances insulin response & fat metabolism

Because of this dual mechanism, Tirzepatide (Mounjaro) results in weight loss of up to 25%

Tirzepatide (Mounjaro) Singapore Update:
Available in Singapore (~ Aug 2025)

Frequently Asked Questions

How soon will I see results?
Most patients notice changes within 4–6 weeks, with significant results by 12 weeks.
We recommend intermittent fasting (16:8) with a 500 kcal daily deficit for best results.
Large clinical trials show long-term safety when medically supervised.
Typically 15-25% of body weight over 6–12 months, depending on several factors such as your current weight, medical history, diet and lifestyle habits
Your doctor will assess your needs, medical history, and goals to recommend the right treatment.
Wegovy vs Ozempic is one of the most common comparisons patients ask about. Both medications contain semaglutide, but Wegovy is approved at a higher dosage, making it more effective for obesity treatment. Ozempic, on the other hand, is approved in Singapore for diabetes management, with weight loss being an off-label benefit.
Due to global supply constraints, Ozempic Singapore availability is limited, with most doses prioritised for diabetic patients in public hospitals. Some private clinics may experience intermittent stock. (Update ~June 2025- Ozempic supply has stabilised)
The most frequently reported Ozempic side effects include nausea, diarrhoea, constipation, headache, and reduced appetite. These are usually mild and improve as the body adapts. More uncommon side effects include injection site reactions and temporary fatigue. Your doctor will monitor you closely to ensure safe treatment.
Is Semaglutide available in Singapore for weight loss?

Yes—Semaglutide is available in Singapore as Wegovy (for obesity). Oral semaglutide (Rybelsus) is also available and is an alternative for patients who prefer not to inject.

Mounjaro contains tirzepatide, which activates both GLP-1 and GIP receptors, giving it a dual-hormone effect. Clinical research shows that Mounjaro may provide greater weight loss than semaglutide injections.
Patients with a BMI over 27 with obesity-related medical conditions such as diabetes or high cholesterol may be prescribed Ozempic, Wegovy or Mounjaro for medical weight management. Those without weight-related conditions will require doctor assessment to determine suitability.
Large clinical studies on semaglutide and tirzepatide show that long-term use is generally safe under medical supervision. Side effects typically are mild, transient and acceptable to most patients. Most patients maintain their weight loss with lifestyle adjustments even after tapering off treatment.
Yes, patients may switch medications if they experience side effects, insufficient weight loss, or supply issues. Your doctor will adjust the dosage safely when transitioning between Ozempic, Wegovy or Mounjaro.
Some weight regain may occur if lifestyle changes aren’t maintained. However, many patients keep most of the weight off by continuing healthy habits such as a calorie-controlled diet and regular exercise. Gradual tapering under medical supervision also reduces rebound risk.
Yes, Tirzepatide (Mounjaro) is available in Singapore for the treatment of obesity and can be obtained from licenced medical clinics and hospitals
