What Is High Blood Pressure? What Causes High Blood Pressure?
High blood pressure is also known as hypertension. Blood pressure is the amount of force exerted against the walls of the arteries as blood flows through them – if a person has high blood pressure it means that the walls of the arteries are receiving too much pressure repeatedly – the pressure needs to be chronically elevated for a diagnosis of hypertension to be confirmed. In medicine chronic means for a sustained period; persistent.
