In Conversation With Patrick Magodzho Deputy Director of Public Health Programmes at the Gauteng Department of Health

The Gauteng Department of Health has raised concern over the growing number of adults under the age of 45 being diagnosed with hypertension, commonly referred to as the “silent killer.” The condition, which often develops without noticeable symptoms, remains one of the leading causes of strokes, heart disease, kidney failure, and premature death globally.
According to the Department, Gauteng recorded 69 125 new hypertension cases between April 2025 and March 2026. Alarmingly, more than 26 000 of these cases were among adults aged between 18 and 44 years old — a trend that signals a major shift in what was traditionally viewed as a condition affecting mostly older people.
Health experts point to several contributing factors behind the increase, including poor diet, obesity, high salt intake, lack of physical activity, smoking, excessive alcohol consumption, chronic stress, and increasingly demanding urban lifestyles. The rise in hypertension among younger adults also reflects broader public health concerns linked to mental health pressures, economic hardship, unemployment, and changing social habits.
The issue comes as the world commemorates World Hypertension Day under the theme “Controlling Hypertension Together!”, which emphasises collective responsibility in improving awareness, prevention, early diagnosis, and treatment adherence.
Despite large-scale screening efforts by the Department — with approximately 8.7 million adults screened during the past financial year — many South Africans remain unaware of their blood pressure status until severe complications occur. Medical professionals continue to warn that hypertension is especially dangerous because symptoms may remain hidden for years while damage silently develops within the body.
The conversation also raises questions around whether younger South Africans are taking preventative healthcare seriously enough, whether modern lifestyles are becoming increasingly unhealthy, and whether healthcare systems are doing enough to educate communities about chronic illnesses before they become life-threatening.
At the same time, experts argue that the growing burden of chronic disease places additional strain on already pressured public healthcare systems, particularly as South Africa simultaneously battles infectious diseases, mental health challenges, and rising healthcare costs.
The discussion will explore the social, economic, lifestyle, and healthcare dimensions of hypertension and why early intervention is becoming increasingly urgent among younger generations.
