Medical Weight Loss Singapore: GLP-1 Injections
Wegovy and Mounjaro are prescription-only medications with robust clinical evidence showing weight loss of 15-22% of body weight. In Singapore, access to these treatments is available through licensed medical clinics, including Noah's telehealth platform.
What Are GLP-1 Receptor Agonists?
GLP-1 (glucagon-like peptide-1) receptor agonists were originally developed for type 2 diabetes management. GLP-1 is a hormone naturally released by the gut after eating. It stimulates insulin secretion, suppresses glucagon, slows gastric emptying, and acts on the hypothalamus to reduce appetite and food cravings.
The Main GLP-1 Medications Available in Singapore
Wegovy (Semaglutide 2.4 mg Weekly Injection)
Wegovy is administered as a once-weekly subcutaneous injection. The STEP 1 trial found semaglutide 2.4 mg produced mean weight loss of 14.9% of body weight over 68 weeks.
Mounjaro (Tirzepatide - Dual GIP/GLP-1 Agonist)
Mounjaro targets two gut hormone receptors - GLP-1 and GIP. The SURMOUNT-1 trial showed mean weight loss of up to 20.9% of body weight at the 15 mg dose over 72 weeks.
Who Qualifies for GLP-1 Weight Loss Treatment?
GLP-1 medications for weight management are indicated for:
- BMI of 30 kg/m2 or higher, or
- BMI of 27 kg/m2 or higher with at least one weight-related comorbidity
A full medical assessment is essential before starting any GLP-1 medication.
Side Effects and What to Expect
The most common side effects are gastrointestinal and occur during dose escalation: nausea, vomiting, diarrhoea or constipation. These typically improve within a few weeks.
