Hypertension, or high blood pressure, is called a “silent killer”. This is because many people who have hypertension may not be aware of the problem as it may not have any symptoms. If left uncontrolled, hypertension can lead to heart, brain, kidney and other diseases. Have your blood pressure checked regularly by a health worker so you know your numbers. If your blood pressure is high, get the advice of a health worker. This is vital in the prevention and control of hypertension.
