Men-jong So-rig Journals. 2010 Feb; 3(1): V.http://imsear.searo.who.int/handle/123456789/177072Pressure of the blood is explained in different ways by different medical systems and depending on the understanding of the Physicians. It is one of the oldest disorders known and affects more than half the world’s population. It is generally termed as the disorder of the rich as it is aggravated by rich unhealthy diet and lack of physical activity associated with rich peoples’ lifestyle. When blood flows through arteries it pushes against the inside walls of the artery. The more pressure the blood exerts on the artery walls, the higher the blood pressure. The size of small arteries also affects the blood pressure. When the muscular walls of arteries are relaxed, or dilated, the pressure of the blood flowing through them is lower than when the artery walls narrow, or constricts. Hypertension is a major health problem, especially because it has no symptoms.It is sometimes referred to as the silent killer. Many people have hypertension without knowing it. Hypertension is more common in men than women and in people over the age of 65 than in younger persons. Hypertension is serious as it increases the risk of heart disease and other medical problems than people with normal blood pressure. If left untreated, hypertension can lead to Arteriosclerosis, heart attack, stroke, enlarged heart and renal failure.enArticle
