For too long, obesity has been dismissed as a personal failing — a lack of willpower, poor discipline, or bad lifestyle choices. That narrative is finally changing in South Africa. At a high-profile World Obesity Roundtable hosted by Novo Nordisk in March 2026, leading endocrinologists and health professionals called for obesity to be treated as what it actually is: a chronic, complex medical condition — not a character flaw.
This shift in thinking has profound implications for how South Africans approach weight loss, how doctors treat patients, and what treatment options are becoming available. Here's what you need to know.

Why Is Obesity Now Called a Chronic Disease?
The World Health Organization and leading medical bodies worldwide have recognised obesity as a chronic disease for over a decade. South Africa has been slower to adopt this framing publicly, but momentum is building rapidly.
According to endocrinologist Dr Reyna Daya, speaking at the Novo Nordisk roundtable: "It's not just a cosmetic issue; it's actually a chronic condition that predisposes us to many health issues."
Novo Nordisk — the manufacturer of Wegovy (semaglutide) with over 25 years of obesity research experience — reports that obesity is linked to more than 200 health complications, including:
- Type 2 diabetes
- High blood pressure (hypertension)
- Cardiovascular disease and stroke
- Sleep apnoea
- Joint damage (osteoarthritis)
- Certain cancers
- Depression and mental health disorders
- Non-alcoholic fatty liver disease
This is not a "lifestyle problem" — it is a biological condition driven by complex interactions between genetics, hormones, gut microbiome, stress, sleep, and environment.
The Stigma Problem in South Africa
One of the biggest barriers to treatment is stigma. Dr Daya highlighted a troubling pattern seen in clinical practice: "Because of all the stigma attached to obesity, people shy away from speaking about it. It's only if patients bring it up during a doctor's consultation that it gets discussed; otherwise it is swept under the rug."
This means millions of South Africans are living with undertreated obesity — not because effective treatments don't exist, but because the conversation never happens. Patients feel shame. Doctors don't raise it proactively. And the result is a silent epidemic that is driving up rates of diabetes, heart disease, and premature death.
South Africa's Obesity Crisis by the Numbers
The scale of the problem in South Africa is sobering:
- South Africa has the highest obesity rate in sub-Saharan Africa
- Over 68% of South African women are overweight or obese
- Approximately 31% of South African men are overweight or obese
- Urban areas (Johannesburg, Pretoria, Cape Town) show the highest rates, driven by sedentary jobs and ultra-processed food availability
- Type 2 diabetes, heavily linked to obesity, affects over 4 million South Africans
These numbers demand a medical response, not a moral judgement.
What Treatment Options Are Available in South Africa?
The good news is that effective, evidence-based treatments for obesity are now available in South Africa — and access is improving. Here is a breakdown of current options:
1. GLP-1 Receptor Agonist Injections
The most effective medications currently available for weight loss are GLP-1 receptor agonists — a class of drug originally developed for diabetes that has shown remarkable weight loss results:
- Ozempic (semaglutide) — Originally for diabetes, widely used off-label for weight loss. Available from most pharmacies with a prescription.
- Wegovy (semaglutide) — The higher-dose version specifically approved for weight loss. Novo Nordisk cut the price in March 2026, improving affordability.
- Mounjaro (tirzepatide) — Eli Lilly's dual GLP-1/GIP agonist showing 20%+ body weight reduction in clinical trials — currently the most effective option on the market.
- Generic semaglutide — Compounded versions available at significantly lower cost, though with varying quality controls.
2. Medically Supervised Diet and Lifestyle Programmes
For patients who do not qualify for medication or prefer a non-pharmacological approach, medically supervised diets remain an effective first-line treatment. These combine:
- Calorie-controlled meal plans (such as a 5000 kilojoule diet)
- Structured exercise programmes
- Behavioural therapy and support
- Regular medical monitoring
3. Bariatric Surgery
For patients with severe obesity (BMI over 40, or over 35 with serious complications), bariatric surgery — such as a gastric sleeve or bypass — is a proven long-term solution. This remains a last resort after other treatments have been tried.
4. Behavioural and Psychological Support
Given the strong links between obesity, stress, emotional eating, and mental health, psychological support is an essential part of any comprehensive weight management plan. Mindful eating practices and stress and cortisol management are particularly important for South Africans dealing with high-pressure lifestyles.
What Needs to Change in South Africa
The medical community is calling for several systemic changes:
Medical Aid Coverage
Currently, most South African medical aids do not cover GLP-1 weight loss medications as a chronic benefit. This is a major barrier — a monthly supply of Wegovy or Mounjaro can cost anywhere from R3,000 to R8,000+ per month. Advocates are pushing for these drugs to be reclassified as chronic disease treatments covered under medical scheme benefits.
Proactive Screening
Doctors need to be trained to proactively discuss obesity with patients — rather than waiting for patients to raise it. A simple BMI calculation at every check-up, combined with a non-judgmental conversation about options, could dramatically improve early intervention rates.
Public Health Education
South Africans need better public education about obesity as a medical condition — not a personal failing. Understanding the hormonal and biological drivers of weight gain (such as cortisol, sleep deprivation, and gut health) helps people seek appropriate treatment rather than blaming themselves.
What You Can Do Right Now
If you are struggling with your weight, here are practical steps you can take today:
- See your GP — Ask specifically about weight management options, including GLP-1 medications if your BMI is 30+
- Calculate your BMI — Use our free BMI calculator to understand where you stand
- Review your diet — Small, sustained changes to eating habits beat crash diets. Explore our South African diet plans for evidence-based guidance
- Move more — Even daily walking has measurable benefits for weight and metabolic health
- Address sleep and stress — Poor sleep and high cortisol actively sabotage weight loss efforts
- Consider supplements — Certain evidence-backed supplements like berberine, magnesium, and omega-3 can support a comprehensive weight management plan
Remember: Obesity is a medical condition, not a moral failure. Effective help is available. The most important step is having an honest conversation with your doctor.
The Bottom Line
The growing recognition of obesity as a chronic disease is one of the most important shifts in South African healthcare in recent years. It opens the door to better treatment, less stigma, and improved access to life-changing medications. Whether you are considering GLP-1 injections, a structured diet programme, or simply trying to make healthier daily choices — the medical community is increasingly on your side.
Stay informed, consult your doctor, and remember: you deserve evidence-based care, not judgment.
