High blood pressure is often called the silent killer because it usually has no warning signs.
In South Africa:
• More than 1 in 3 adults are living with high blood pressure.
• More than 50% don't know they have it.
• It's responsible for 1 in every 2 strokes and 2 in every 5 heart attacks.
A simple blood pressure check takes just a few minutes and could make all the difference.
