What is Hypertension?
1/10
Hypertension, commonly known as high blood pressure, is when the arteries experience high blood pressure. Blood pressure is the pressure of blood against the walls of arteries. The heart pumps blood to the whole body through arteries. When the arteries are narrowed, the heart has to work extra to pump the blood, which results in elevated blood pressure.
The normal blood pressure level is when it is lower than or equal to 120/80 mmHg. When these figures increase and persistently remain higher (140/90 mmHg or more) the condition is called hypertension.
