High blood pressure (HBP) or hypertension means high pressure (tension) in the arteries. Arteries are vessels that carry blood from the pumping heart to all the tissues and organs of the body. High blood pressure does not mean excessive emotional tension, although emotional tension and stress can temporarily increase blood pressure.
Hypertension or blood pressure is the force exerted by your heart, against the resistance created by the arteries, to keep blood flowing through your body. Your blood pressure is high (hypertension) when the force is excessive.
Clinically we define it as a sustained increase in blood pressure - the main point being that one-off measurements don t mean much in themselves, and that a repeatable demonstration of high blood pressure is required. These days, the classification is as follows (EITHER diastolic or systolic number puts you up to the next class): Normal/optimal - lt;120/80 High Normal - lt;130/85 Pre-Hypertensive - 130/85 to 140/90 Stage I Hypertension - 140/90 - 160/100 Stage II Hypertension - 160/100 - 180/110 Stage III Hypertension - gt;180/110
