High blood pressure is caused by "Cardiovascular (ARTERY) blockage" which in most cases is caused by calcium plaque. When arteries are restricted and blood flow is reduced the heart (our blood pump) has to work harder and at higher pressure to keep the same amount of blood flowing in bad arteries. You don’t have to have all your arteries restricted; just one or two areas and they will act like a dam holding back the blood flow increasing your blood pressure.
Think of it this way, if your pipes at home are unclogged and clean then your water flow is good. The same thing happens in your body, when your arteries are open your blood pressure is low and you will feel young and healthy.

In 90–95 percent of cases, scientists don’t know what causes high blood pressure. This is essential hypertension. Fortunately, although scientists don’t fully understand the causes of this disease, they’ve developed both non-drug and drug treatments that treat it effectively. They’ve also identified some factors that contribute to higher blood pressure. These are arteriosclerosis (or hardening of the arteries), thickening or hypertrophy of the artery wall, and excess contraction of the arterioles (small arteries).
In the remaining cases, high blood pressure results from a recognizable underlying problem. This is called secondary hypertension. Some possible causes are a kidney abnormality, tumor of the adrenal gland or congenital defect of the aorta. When the root cause is corrected, blood pressure usually returns to normal.

Smoking,lack of exercise,weight,stress and sodium in your diet are also causes of high blood pressure.
