A plain-language guide to what GLP-1 is, how the medication works, and which versions are available in South Africa.
GLP-1 (glucagon-like peptide-1) is a hormone your gut releases after you eat. Its job is to help you manage blood sugar and tell your brain you've had enough food. For most people, the system works as it should. For others, the GLP-1 response is weaker, which makes appetite and blood sugar harder to manage day to day.
This is one of the reasons weight gain isn't a willpower problem. The biology underneath can genuinely be different.
GLP-1 medications are receptor agonists. They bind to the same receptors as the body's natural GLP-1 and produce its effects at a higher dose and for longer. They act on three main systems.
The medication acts on GLP-1 receptors in the brain's appetite-regulation centres, reducing persistent food cravings and the constant preoccupation with eating that makes consistent dietary changes difficult.
By delaying gastric emptying, GLP-1 keeps food in the stomach for longer. Satiety is reached sooner during meals and sustained between them, reducing meal size and the urge to snack.
GLP-1 stimulates insulin release when blood sugar rises and suppresses glucagon. This flattens the spikes and crashes that drive cravings and fatigue, with the strongest effect seen in patients with type 2 diabetes.
Three GLP-1 medications are prescribed in South Africa: Wegovy and Mounjaro for chronic weight management, and Ozempic, which contains the same active ingredient as Wegovy but is registered for type 2 diabetes. Each is dosed differently, and the mechanisms vary slightly. The full comparison is on the GLP-1 medications page.
GLP-1 medication is for adults whose weight has become a clinical issue, often because it's contributing to other conditions like type 2 diabetes, high blood pressure, sleep apnoea, or raised cholesterol, or because weight has been hard to manage with diet and exercise alone.
Whether GLP-1 is right for you is decided clinically, not by a calculator. A doctor reviews your full medical picture: what you've already tried, what's working, what's not, and what your other health markers look like.
The Loome eligibility check takes two minutes and a real clinician reviews your answers. If GLP-1 is worth exploring, they'll say so. If it isn't, they'll tell you why and what to do next. Check if I qualify →
GLP-1 medication isn't a shortcut or a cure. It's a treatment, and like any medication, it works best alongside the rest of the care: the food changes, the strength work, the support, and the follow-up. The patients who do well on it are the ones who treat it as part of a plan.
GLP-1 medication is prescription-only in South Africa and dispensed by licensed pharmacies. Buying it without a prescription, from informal sources, or from unregulated online sellers carries serious medical risk.
Loome is a fully digital weight-loss programme for South African adults. A real clinical team, real ongoing care, and GLP-1 medication where it's the right call. The eligibility check takes two minutes.
