Who qualifies for weight-loss medication in South Africa

The short answer

This class of treatment is for adults carrying excess weight that is affecting their health. It is not a quick fix for someone who wants to lose a few kilograms before a wedding or a holiday. In South Africa a GLP-1 medication is doctor-supervised, so an HPCSA-registered doctor has to assess you before anything is dispensed.

There are well-recognised starting points that doctors use to decide who is a reasonable candidate. Think of them as a guide rather than a promise. The final decision always sits with the doctor.

The BMI thresholds

Body mass index, or BMI, compares your weight to your height. It is a blunt tool, but it gives a doctor a sensible place to begin the conversation.

Most guidelines point to two thresholds:

• A BMI of 30 or above. This sits in the range usually described as obesity and can be a starting point on its own.
• A BMI of 27 or above, together with a weight-related health condition. Here the added risk from that condition lowers the bar.

You can estimate your own BMI by dividing your weight in kilograms by your height in metres squared. A doctor will check it properly and, importantly, look at far more than that single number.

Which conditions count

The conditions that matter are the ones that tend to travel with extra weight and often improve when weight comes down. They include:

• Type 2 diabetes
• High blood pressure
• High cholesterol
• Sleep apnoea
• Fatty liver

If you live with one of these and your BMI is 27 or higher, you may qualify even though you are not in the obesity range. If you are unsure whether a diagnosis you have been given counts, your doctor can tell you.

Adults only

These medicines are intended for adults. They are not a general treatment for children or teenagers, and a doctor will not start someone on this path simply because they ask for it. Age is one of several boxes that need to be ticked, not the only one.

When it is not suitable

Some situations mean this treatment is not the right choice, regardless of your BMI. A doctor will rule it out if any of the following apply:

• You are pregnant, planning a pregnancy or breastfeeding.
• You have a personal or family history of medullary thyroid cancer.
• You have multiple endocrine neoplasia type 2, known as MEN 2.

Your doctor will also ask about other medicines you take, your gut health and any past reactions, because these can change what is safe for you.

Why a doctor makes the final call

Two people can share the same BMI and still need different plans. One might have a thyroid history that rules this out. Another might be on medication that needs adjusting first. This is exactly why the decision cannot be made by a calculator or a website.

A registered doctor weighs your full picture: your weight history, your health conditions, what you have already tried and what you are hoping to achieve. Only a SAHPRA-registered medicine will be considered, and only when the doctor judges the likely benefit to be worth it for you.

What to expect if you do qualify

Qualifying is the beginning, not the finish line. Treatment works alongside changes to how you eat and move, and it is reviewed regularly. In clinical trials, average weight loss has ranged from roughly 8% to over 20% of body weight, depending on the specific medication and dose. Results vary from person to person, and your own outcome may sit above or below those figures.

Cost matters too. Prices are set in Rand, and cover from local medical aids differs from one scheme and plan to the next, so it is worth checking your own benefits early.

This is general information and not medical advice. Whether this treatment suits you is a decision for a registered doctor who has assessed your health.

If the thresholds above sound like they might describe you, the sensible next step is a proper assessment. Book a consultation with a doctor to find out where you stand.
