9 Best Weight Loss Clinics in Singapore (August 2026)

Before the list, here is how I weighed these clinics. Medical weight loss is a health decision, not a beauty purchase, so my criteria are about safety and substance, not before-and-after marketing.

• Doctor-led and HSA-compliant. The programme should be run by registered doctors who prescribe medication responsibly. GLP-1 drugs like Wegovy and Mounjaro are prescription-only medicines under the Health Sciences Authority, so a proper consultation and prescription are non-negotiable. Be wary of anywhere offering them without one.
• Honest eligibility assessment. A good clinic checks whether medication is actually appropriate for you, usually against the lower Asian BMI thresholds the Health Promotion Board uses, and is willing to say no if it is not. A clinic that prescribes to everyone who walks in is a red flag.
• Proper monitoring and follow-up. Weight medication needs dose titration, side-effect management, and regular review. I look for structured programmes with body composition tracking and scheduled follow-ups, not a one-off prescription.
• A real lifestyle component. Medication works best alongside nutrition and habit change. The clinics I rate pair the drug with dietary and lifestyle support so the results hold once you eventually taper off.
• No guarantees, no hype. Nobody can promise you a specific number on the scale. I trust clinics that set realistic expectations (typically a meaningful percentage of body weight over several months) over those selling a dream.

The right clinic often comes down to the right medication, and each of the main GLP-1 options has its own profile. If you already know, or suspect, which one you want, here are my dedicated guides:

• Wegovy (semaglutide): the version purpose-dosed for weight management. See the best Wegovy clinics in Singapore.
• Ozempic (semaglutide): registered for diabetes and used off-label for weight. See the best Ozempic clinics.
• Mounjaro (tirzepatide): a dual-action medicine with the largest average results. See the best Mounjaro clinics.
• Saxenda (liraglutide): a daily injection that can be a sensible first GLP-1. See the best Saxenda clinics.
• Rybelsus (oral semaglutide): a daily tablet for the needle-averse. See the best Rybelsus clinics.
• Duromine (phentermine): an older appetite suppressant, a controlled stimulant used short-term. See the best Duromine clinics.
• Xenical (orlistat): a non-stimulant fat blocker that works in the gut. See the best Xenical clinics.

Your doctor is the one to confirm which medication fits you, but knowing the options helps you ask better questions at your consultation. One you may have heard of, Contrave (naltrexone-bupropion), is not currently available in Singapore as a single registered weight-loss tablet, so doctors here prescribe its components separately rather than as a branded product.

Because GLP-1 medications are prescription-only, clinics cannot publicly advertise specific medication prices, so the figures below are indicative market ranges for 2026, not quotes. Your actual cost depends on the medication, your dose, and the clinic's programme structure, and the medication itself is usually the largest part of the bill.

Two things move the price. The first is the drug and the dose, which rises as you titrate upward in the early months. The second is how much wraparound care (coaching, nutrition, reviews) is bundled in. Ask each clinic for an all-in monthly estimate so you are comparing like with like, and remember the cheapest option is rarely the point with medication you inject into your body.

GLP-1 medications mimic a natural gut hormone (glucagon-like peptide-1) that your body releases after eating. They work mainly by slowing how quickly your stomach empties and acting on appetite signals in the brain, so you feel full sooner and stay full longer. The result for most people is that they simply eat less without the constant battle against hunger.

The newer drugs build on this. Semaglutide (Wegovy, Ozempic) targets the GLP-1 pathway, while tirzepatide (Mounjaro) targets two hormone pathways (GLP-1 and GIP), which is why it tends to produce the largest average results. They are taken as a weekly injection (Saxenda is daily), with the dose increased gradually to manage side effects. They are tools that make healthy eating easier, not a substitute for it.

Eligibility is a medical decision a doctor makes with you, but it generally follows body mass index (BMI) thresholds, and Singapore uses lower cut-offs for Asian populations. The Health Promotion Board treats a BMI of 23 and above as higher risk and 27.5 and above as high risk, lower than the global figures of 25 and 30.

In practice, weight loss medication is typically considered for a BMI around 30 and above, or around 27 and above if you also have a weight-related condition such as type 2 diabetes, high blood pressure, or high cholesterol. A responsible clinic will assess your BMI, your health history, and your goals, and will tell you if medication is not the right path. That willingness to say no is one of the clearest signs of a clinic worth trusting.

GLP-1 medications are approved and widely used, and for eligible people they are generally considered safe under medical supervision, which is exactly why the prescription and monitoring requirements exist. They are regulated by the HSA, and Singapore's broader push on metabolic health through the Ministry of Health reflects how seriously weight-related disease is now taken.

The most common side effects are gastrointestinal: nausea, constipation, or an upset stomach, especially in the first weeks and when the dose increases. These usually settle, and gradual dose titration is designed to limit them. Less commonly there are more significant risks, which is why a proper consultation, an honest medical history, and ongoing follow-up matter so much. This is general information, not medical advice, so discuss the specifics with your doctor.

They are related but not identical. Wegovy and Ozempic are both semaglutide; Wegovy is the version dosed for chronic weight management, while Ozempic is registered primarily for type 2 diabetes and is often used off-label for weight by doctors. Saxenda is liraglutide, an older GLP-1 drug taken as a daily injection rather than weekly. Mounjaro is tirzepatide, a dual GLP-1/GIP medication that tends to deliver the largest average weight loss in studies.

Which is right for you depends on your health profile, how your body responds, tolerability, and cost, which is precisely the decision a doctor-led clinic is there to make with you. There is no single best drug, only the best fit, and that is the whole reason to choose a clinic that carries options and assesses you properly rather than one that pushes a single product.
