Experts warn that what was once viewed as a distant threat has become an urgent national crisis. Lifestyle‑related diseases have rapidly become the leading cause of death and a major driver of healthcare demand in South Africa. Non‑communicable diseases (NCDs) – including heart disease, diabetes, hypertension and stroke – now account for more than half of all deaths in the country, underscoring the severity of the situation. This surge in preventable chronic conditions is placing unprecedented strain on the healthcare system and deepening the social and economic consequences nationwide.
The risk factors behind the rise
Unhealthy eating habits, sedentary lifestyles, excessive alcohol use and smoking are key drivers of chronic conditions, and the statistics are concerning. More than 1 in 3 adults in South Africa live with hypertension and many (over 50%) are unaware of their conditions until complications arise, which highlights the importance of regular screenings, preventative measures and early detection.
“The reality is that lifestyle-related diseases are no longer a future concern. They are here and continue to affect more South Africans every year,” says Dr Dion Kapp, Executive of Managed Healthcare and Service Providers at Bestmed Medical Scheme. “The encouraging part, however, is that many of these conditions are preventable and manageable with early intervention and healthier habits.”
Prevention starts with simple choices
Dr Avron Urison, Chief Medical Officer at 1Life Insurance agrees, emphasising that meaningful change starts with small, consistent actions. “A healthier lifestyle is not about perfection or costly programmes. It starts with simple choices that fit naturally into everyday life – moving more, mindful eating, quitting smoking, limiting alcohol, improving sleep, managing stress and keeping up with routine check-ups.”
“Studies show that nutrient-rich diets support mental health, improving mood, brain function and overall wellbeing,” adds Dr Urison.
Practical dietary choices are critical, including:
- choosing home-cooked meals over processed foods.
- increasing fruit and vegetable intake.
- drinking water instead of sugary beverages.
- opting for whole grains and nutrient-rich foods.
However, preventative measures go beyond just eating healthy and staying active. There are several other strategies that can make a difference including:
- routine screenings and regular check-ups, as early detection allows for timely interventions.
- staying up to date with vaccinations and immunisations for both children and adults to strengthen immunity and help prevent illnesses that could worsen chronic conditions.
“Bestmed’s 2025 data highlights both the growing burden of chronic disease and the measurable impact of preventative care,” says Dr Kapp. “More than 90 000 members were registered for chronic conditions (including 51% with hypertension, 13.6% with diabetes, and 34.6% with hyperlipidaemia). Hypertension remains the most prevalent diagnosis.
At the same time, uptake of preventative benefits showed encouraging trends as 7% of members made use of their benefits, up from 5.7% in 2024, while over 30 000 members made use of vaccination benefits, including flu and other recommended immunisations for both adults and children.
Why prevention matters
Despite this, many South Africans remain unaware of the chronic conditions they may already have, which is also driving up long-term healthcare costs.
According to the Council for Medical Scheme Industry Report released in 2025, total healthcare expenditure on benefits paid in 2024 reached R259.3 billion – up by 8.52% from 2023 – largely driven by chronic disease management, which requires ongoing care, medications and, in severe cases, hospitalisation.
Prevention is not just about reducing healthcare costs; it’s about improving quality of life, financial stability and community wellbeing. Encouraging healthier habits today can translate into fewer complications and lower medical expenses, as well as a more productive and resilient society.
Experts like Dr Kapp and Dr Urison are urging South Africans to take their health seriously. By making small, consistent choices from healthier eating and regular exercise to routine screenings, individuals can reduce future risks and contribute to a stronger, healthier nation.
“If we don’t prioritise prevention today, the pressures on families and the healthcare system will continue to intensify,” Dr Kapp concludes. “Every small decision count towards a healthier future.”
