World Obesity Day – SA launches own national guidelines

Obesity is a chronic disease. And we now have a national clinical guideline to treat it properly.

South Africa’s first national obesity guidelines confront a crisis affecting more than 10 million people. Nearly one in three South African adults is living with obesity — more than 10 million people — and over 40% of women are affected, according to national epidemiological research published in the South African Medical Journal. Against this backdrop, South Africa has released its first comprehensive national clinical guidelines for the management of obesity, formally recognising the condition as a chronic, relapsing medical disease and providing an evidence-based roadmap for treatment.

Published in a special issue of the South African Medical Journal and developed by leading local clinicians and researchers from the South African Metabolic Medicine and Surgery Society (SAMMSS), the guideline integrates the latest international medical science with the realities of the South African healthcare context. They represent a significant shift in how obesity should be understood, discussed and treated — by both medical professionals and the public.

At the same time, public conversation has been dominated by GLP-1 medications and social media commentary describing treatment as “the easy way out” or “cheating.” The guidelines bring the debate back to science. They outline a structured continuum of care that includes clinical assessment, medical nutrition therapy, behavioural and psychological support, pharmacotherapy where clinically indicated, bariatric and metabolic surgery for appropriate candidates, and long-term follow-up.

Medication and surgery are not positioned as cosmetic or quick fixes. They are confirmed as evidence-based tools within long-term chronic disease management. The guideline also caution against irresponsible use, including black-market access to GLP-1 medications without proper nutritional, psychological and medical supervision. Used within structured care, these therapies can be life-changing. Used outside of clinical guidance, they carry risks. The distinction is clear.

The guidelines define obesity as a complex chronic disease characterised by excess or dysfunctional adiposity that impairs health. They recognise the biological regulation of appetite and metabolism, the influence of genetics and environment, and the relapsing nature of the condition. For millions of South Africans who eat healthily, exercise regularly and succeed in demanding areas of life yet struggle with sustained weight management, this is not an excuse — it is validation.

Obesity is not a failure of willpower. It is a medical condition requiring medical care.

The document also emphasises the impact of obesity-related comorbidities — diseases caused or worsened by severe obesity — including type 2 diabetes, hypertension, cardiovascular disease and sleep apnea. Treating only these complications without addressing obesity itself is incomplete care. Effective obesity management improves overall health outcomes and reduces long-term disease burden.

The primary aim of the guidelines is to educate healthcare professionals on the full scope of obesity management. Nutrition and physical activity remain foundational, but the document makes clear that obesity care extends far beyond lifestyle advice. It requires multidisciplinary understanding, appropriate use of medication, careful surgical criteria and long-term follow-up.

Importantly, the guidelines are publicly available. Individuals living with obesity, and their families, can access the full document in the South African Medical Journal.

Patients are encouraged to become informed advocates for themselves. If a healthcare provider does not recognise obesity as a chronic disease or is unfamiliar with the full continuum of treatment options, patients can refer them to the national guideline and to SAMMSS for further professional education and training.

The top facts for people living with obesity to understand are:

1. Obesity is a chronic medical disease — not a lifestyle choice.
2. It is not a willpower failure, but it is my responsibility to seek treatment.
3. Weight is biologically regulated — hunger, metabolism and regain are medically influenced.
4. Obesity drives serious comorbidities such as diabetes, hypertension and heart disease.
5. There is a full range of care — from nutrition and physical activity to medication and surgery.
6. Medication and surgery are not “quick fixes” — they are evidence-based tools in long-term care.
7. Weight regain is not failure — obesity is a relapsing condition that requires ongoing management.
8. Stigma harms health — science, structured care and respect improve outcomes.

The publication of these national guidelines marks a turning point. The conversation can now shift from blame to biology, from stigma to structured care, and from fragmented treatment to coordinated, evidence-based management.
