Theme for 2025: “Measure your blood pressure accurately, control it, live longer.”

World Hypertension Day (WHD) is observed annually on 17 May to raise awareness about high blood pressure—a major contributor to non-communicable diseases (NCDs) and the leading global risk factor for death and disability.

💡 Why It Matters

• Hypertension (high blood pressure) occurs when the force of the blood against your artery walls is too high.

• It is often called the “silent killer” because it has no symptoms, yet leads to serious health problems.

• It is the most common risk factor for:

  • Heart disease

  • Stroke

  • Kidney failure

According to the World Health Organization:

• 1 in 6 people globally are affected by high blood pressure.

• It is the top cause of cardiovascular deaths.

🚨 Key Risk Factors

• High salt intake

• Tobacco and alcohol use

• Poor diet

• Lack of physical activity

• Stress

• Air pollution

🩺 The Importance of Early Detection

• Many people don’t know they have high blood pressure.

• Without control, it can lead to:

  • Heart attacks

  • Strokes

  • Kidney damage

  • Early death

Regular blood pressure screening, healthy lifestyle changes, and salt reduction can dramatically reduce risks.

🇿🇦 Focus on South Africa

In South Africa, primary healthcare plays a crucial role in:

• Preventing hypertension

• Managing diagnosed cases

• Reducing heart and kidney-related complications

Accessible primary care services are key to long-term health and wellness in local communities.
