South Africa’s Diabetes Crisis: Why Urgent Action is Needed to Prevent a Public Health Disaster

Every year, approximately 60,000 South Africans die before the age of 70 from diseases not caused by infections like HIV or TB. A significant portion—around 20%—of these deaths are attributed to diabetes, a disease that is largely preventable. The severity of South Africa’s diabetes crisis is a wake-up call for urgent intervention, as the country faces a steady rise in premature deaths linked to non-communicable diseases (NCDs).

In 2020 alone, diabetes claimed the lives of 32,000 South Africans, with 40% of the victims dying before they turned 65. This number surpasses the 22,000 deaths caused by tuberculosis (TB), a curable infectious disease, highlighting the growing danger posed by diabetes. While TB deaths have decreased significantly over the last decade, diabetes has become the leading cause of premature death in South Africa, raising alarm bells among health experts.

The Unseen Epidemic

Diabetes, a chronic condition where the body struggles to regulate blood sugar, has steadily emerged as a major public health concern. The World Health Organization (WHO) has identified it as one of the four main NCDs to target in efforts to reduce early deaths by 25% by 2025. But South Africa is falling short of meeting this ambitious goal, with little progress made in curbing the rise of diabetes and other preventable diseases.

In 2019, NCDs led to around 61,000 premature deaths in South Africa. This number has remained largely unchanged since 2010, and the country is nowhere near the target set by the WHO. Experts like Zandile Mchiza from the South African Medical Research Council (SAMRC) point to poor healthcare access, unhealthy lifestyle choices, and rising obesity rates as major factors contributing to the diabetes crisis. Adding fuel to the fire, the high prevalence of TB in South Africa further exacerbates the risk of developing diabetes.

Gaps in Diabetes Care and Data

Despite efforts to tackle diabetes, progress in South Africa has been slow. A major hurdle is the lack of comprehensive data collection and monitoring. Many clinics still rely on paper-based records, making it difficult to track the prevalence of diabetes and assess the effectiveness of health interventions. Patrick Ngassa Piotie, chair of the Diabetes Alliance, stresses the importance of accurate data to formulate effective policies and prevent further deaths.

Without a robust system to monitor and manage diabetes, it’s impossible to understand the full scope of the problem. Early detection and better management of the disease could prevent countless complications, including blindness, amputations, and heart disease, which in turn would reduce the burden on South Africa’s healthcare system.

The Economic and Social Cost of Inaction

The impact of diabetes is not just felt in the healthcare sector—it extends to the economy as well. In 2018, the government spent a staggering R2.7 billion on diabetes-related healthcare costs. If the estimated 1.2 million undiagnosed cases were factored in, the cost would have soared to R21.8 billion—nearly 10% of South Africa’s total healthcare budget. The financial strain is unsustainable, especially considering that many people affected by diabetes are in their prime working years, between 35 and 64 years old.

The economic toll of diabetes goes beyond healthcare costs. The disease often leads to missed work, disability, and even job loss, which in turn impacts entire families and communities. The need for preventative measures—such as promoting healthier diets, increasing physical activity, and reducing smoking—is clear. Addressing these factors could not only save lives but also reduce the long-term economic burden of diabetes.

A Path Forward: Prevention and Early Intervention

The solution to South Africa’s diabetes crisis lies in a combination of prevention, early diagnosis, and improved treatment. Encouraging healthier lifestyles and making diabetes screening more accessible could dramatically reduce the number of people suffering from the disease. Moreover, a coordinated national effort involving the government, healthcare providers, and communities is essential for achieving the WHO’s target of reducing premature deaths from NCDs.

The stakes are high. If South Africa continues to neglect the growing diabetes crisis, the consequences will be devastating—both in terms of lives lost and the economic strain on the healthcare system. It’s time for urgent action to address this preventable epidemic before it’s too late.
