Blood pressure

One must understand blood pressure in simplest form for which doctors have no time to explain. "Pressure on arterial walls is blood pressure " why it increases?Following could be attributed to high blood pressure 
1. Cholesterol gets deposited on arterial walls,causing narrowing of arteries and reducing available space for blood flow thereby increasing pressure on arterial walls. 
2. Hardening of arteries. Cholesterol deposition and ageing process causes hardening of arteries,known as atherosclerosis.Arteries loose it's natural elasticity resulting in high BP. 
3. Water retention. It's caused by some medical conditions like kidney problems etc.,commonest cause of water retention is access salt and alcohol intake. In both the conditions blood volume increases which in turn raises blood pressure.
 4. Constriction of arteries. It's caused mainly due to stress,smoking or intake of nicotine. When arteries are constricted blood pressure increases. 
When one takes medicine it gives relief of symptoms by relaxing arteries or by reducing heart rate or its force but does not eliminate underlying causes discussed above and one gets feeling of cured and continues with unchanged life style, harbouring disease in perpetuity.

High Blood pressure (hypertension) is one of the most common and dangerous health issue may put your valuable life in danger. As you are getting older hypertension may leads to damage your blood vessels may cause serious diseases like heart stroke, heart disease, kidney failure and many more.

The force with which the blood flows across the blood vessels is blood pressure.
In a more definitive way, the lateral pressure exerted by a column of blood against the arterial walls is know as blood pressure.
