The Association for Diabetics in South Africa (ADSA) recently stated that more than 50% of South Africans are overweight or living with obesity, the highest figure on the continent.

Pretoria Rekord reports the medical condition affects 68% of women and 31% of men, while overweight and obesity rates among children also remain among the highest in Africa.

Obesity-related conditions, including type 2 diabetes, hypertension and cardiovascular disease, contribute significantly to the country’s non-communicable disease burden.

ADSA stated that obesity is estimated to cost South Africa more than R33b a year in direct healthcare expenditure alone.

Bariatric and laparoscopic surgeon Dr Nkosikhona Mlimi from Mediclinic Medforum in Arcadia says despite growing awareness, obesity remains one of the most misunderstood medical conditions, often surrounded by myths and stigma that prevent many people from seeking help.

“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. Effective treatment options are available, and with the right support, patients can achieve meaningful improvements in their health, confidence, and quality of life,” Mlimi says.

Common myths about obesity

The doctor lists some myths he often comes across in his practice and explains the facts behind the disease.

Myth: Obesity is simply a result of laziness.

Fact: Obesity is a complex disease influenced by genetics, hormones, metabolism, environmental factors, medications and lifestyle choices. It is not simply a matter of willpower.

Myth: People with obesity just need to eat less and exercise more.

Fact: While healthy eating and physical activity are important, many patients struggle with biological factors that make long-term weight loss difficult. Medical and surgical interventions may be necessary for sustainable results.

Myth: Bariatric surgery is the easy way out.

Fact: Bariatric surgery is a major medical intervention that requires commitment, lifestyle changes, nutritional management and ongoing follow-up care. It is a tool that helps patients achieve and maintain healthier lives.

Myth: Bariatric surgery is only about losing weight.

Fact: Bariatric surgery can significantly improve or even resolve conditions such as type 2 diabetes, hypertension, sleep apnoea, fatty liver disease and obesity-related joint problems.

Myth: Obesity only affects appearance.

Fact: Obesity affects nearly every organ system in the body and can shorten life expectancy if left untreated.

“Individuals who struggle with obesity despite repeated efforts at diet and exercise should speak to their healthcare provider about available treatment options. Your journey to better health starts with a conversation,” Mlimi says.

Who may qualify for bariatric surgery

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 are living with obesity-related complications affecting their health and quality of life.
