South Africa's obesity crisis strains health systems; clinical care, not shame, needed now

SOUTH AFRICA’S OBESITY BURDEN DEMANDS CLINICAL INTERVENTION, NOT STIGMA

More than half of South Africa’s population is classified as overweight or obese, according to the Association for Diabetics in South Africa (ADSA), placing the country at the top of the continent for prevalence. The condition affects 68 percent of women and 31 percent of men. Among children, overweight and obesity rates rank similarly among Africa’s highest. The financial toll is concrete: ADSA estimates obesity costs the country more than R33 billion annually in direct healthcare spending alone.

That burden falls on a health system already stretched by non-communicable disease. Yet misconceptions about obesity continue to block access to treatment and reinforce stigma that keeps patients from seeking care. Dr Nkosikhona Mlimi, a bariatric and laparoscopic surgeon at Mediclinic Medforum in Arcadia, is direct about what the condition actually is. “Obesity is not a personal failure. It is a medical condition that deserves the same compassion, understanding, and treatment as any other chronic disease. No one should suffer in silence or feel ashamed to seek help,” Mlimi says.

The disease’s reach is wide. Obesity-related conditions, including type 2 diabetes, hypertension and cardiovascular disease, contribute substantially to South Africa’s non-communicable disease burden. Left untreated, obesity can shorten life expectancy. The problem is not only biological. Common myths about the condition persist in clinical practice and public understanding alike, creating real barriers to effective intervention.

One widespread misconception frames obesity as a failure of willpower or discipline. In reality, the condition involves complex interactions between genetics, hormones, metabolism, environmental factors, medications and lifestyle choices. A second myth suggests that diet and exercise alone resolve obesity in all cases. While healthy eating and physical activity remain important, many patients face biological factors that make sustained weight loss difficult without medical or surgical support.

A third myth is particularly consequential for patients who might benefit most from surgery. Bariatric procedures are often portrayed as an easy shortcut. They are not. The surgery is a major medical intervention requiring significant commitment, lifestyle restructuring, nutritional management and ongoing follow-up care.

By contrast, the clinical benefits of bariatric surgery extend well beyond weight reduction. The procedure can significantly improve or resolve type 2 diabetes, hypertension, sleep apnoea, fatty liver disease and obesity-related joint problems. A further misconception frames obesity as primarily a cosmetic concern, when in fact the condition affects nearly every organ system in the body and poses serious health risks if left untreated.

Patients with a body mass index of 35 or higher who have experienced repeated unsuccessful weight-loss attempts and are living with obesity-related complications may qualify for bariatric surgery. The procedure functions as a clinical tool to help patients achieve and maintain healthier lives, not as a standalone solution. Mlimi is clear that individuals struggling with obesity despite sustained efforts at diet and exercise should consult their healthcare provider about available treatment options. “Your journey to better health starts with a conversation,” he says.

Whether South Africa’s health system can reduce the stigma that delays those conversations, and expand access to clinical intervention for the millions who qualify, remains the practical challenge ahead.
