In simple language hypertension is generally used to describe elevated blood pressure level than the normal limit which is the estimation of the force against the arteries walls. It is categorized in to two category namely Primary or Essential Hypertension and the other one is Secondary Hypertension. Generally 90-95% cases of hypertension are of Primary hypertension, which is the high blood pressure with no obvious cause. Rest are the cases caused by other conditions and are associated with risk to kidney, endocrine system, arteries etc. (Carretero OA, Oparil S, January 2000)
Blood pressure is expressed in terms of mmHG and usually provided as two values as 120 over 80 (120/80 mmHG). The upper number indicates systolic pressure and is considered high if the value is over 140 most of the time. The bottom number is the diastolic pressure and is considered high if the value remains over 90 most of the time. (Kaplan NM. Systemic Hypertension: Therapy)
