OBESITY MYTHS DEBUNKED AS SOUTH AFRICA FACES GROWING HEALTH CRISIS
More than half of South Africa’s population carries excess weight or lives with obesity, a public health emergency that extends far beyond individual body image concerns. The condition now ranks as the highest prevalence rate on the African continent, according to the Association for Diabetics in South Africa (ADSA), and its consequences touch nearly every aspect of citizens’ wellbeing and healthcare access.
The scale is stark. Women bear a disproportionate burden, with 68% affected by overweight or obesity, compared to 31% of men. Children across the country also experience rates among Africa’s highest. These figures translate into a measurable drain on public health resources: obesity-related conditions cost South Africa more than R33 billion annually in direct healthcare expenditure alone. That figure reflects the real pressure on a healthcare system already stretched thin, affecting everything from hospital capacity to treatment availability for the broader population.
The health consequences ripple through the nation’s disease landscape. Obesity-related conditions including type 2 diabetes, hypertension and cardiovascular disease now contribute significantly to South Africa’s non-communicable disease burden. These are not isolated individual problems. They represent a collective crisis that shapes health outcomes across communities and strains the very infrastructure ordinary citizens depend on for care.
A critical barrier stands in the way of effective treatment: widespread misunderstanding and stigma surrounding obesity itself. Dr Nkosikhona Mlimi, a bariatric and laparoscopic surgeon at Mediclinic Medforum in Arcadia, emphasizes that obesity remains profoundly mischaracterized as a personal failing rather than a medical condition deserving serious clinical attention. “Obesity is not a personal failure. It is a medical condition that deserves the same compassion, understanding, and treatment as any other chronic disease,” Mlimi states. “No one should suffer in silence or feel ashamed to seek help.”
That stigma directly undermines public health by discouraging people from accessing treatment.
Mlimi identifies several persistent myths that block pathways to care. Many people believe obesity results simply from laziness or lack of willpower. In reality, the condition emerges from a complex interplay of genetics, hormones, metabolism, environmental factors, medications and lifestyle choices. The widespread assumption that diet and exercise alone solve obesity similarly overlooks the biological factors that make sustained weight loss difficult for many patients, often requiring medical or surgical intervention.
Misconceptions about treatment options themselves pose another barrier. Bariatric surgery is frequently dismissed as “the easy way out,” when in fact it represents a major medical intervention demanding significant commitment, lifestyle restructuring, nutritional management and ongoing follow-up care. More importantly, the public often views such surgery as purely cosmetic, when its actual impact extends to resolving or substantially improving type 2 diabetes, hypertension, sleep apnoea, fatty liver disease and obesity-related joint problems. These health improvements directly enhance citizens’ capacity to work, participate in daily life and reduce their dependence on ongoing medical care.
By contrast, the misconception that obesity affects only appearance masks a deeper public health reality: the condition impacts nearly every organ system in the body and can shorten life expectancy if untreated. This reality underscores why treatment access matters not as a personal choice but as a public health imperative.
Bariatric surgery may be appropriate for patients with a body mass index of 35 or higher who have experienced repeated unsuccessful weight-loss attempts and live with obesity-related complications. Mlimi urges individuals struggling with obesity despite sustained dietary and exercise efforts to consult their healthcare providers about available options. “Your journey to better health starts with a conversation,” he says, framing treatment not as shame-based intervention but as a standard healthcare decision.
Whether South Africa’s healthcare system can meet the scale of this challenge, given the R33 billion annual burden and the millions of citizens already affected, remains an open question that policymakers, clinicians and communities will need to confront together.
