High blood pressure, medically known as hypertension, is the major risk factor for heart disease, strokes, kidney disease and even eye diseases. When blood pressure exceeds a certain threshold, we call it high blood pressure.
Approximately four in 10 adults older than 25 have hypertension. This means that nearly one billion people have hypertension. The unfortunate part is that around 50% of these people are unaware of their condition.
