Question

what us blood pressure

Answer 1

I have answered this question. Part of it I am rewriting here.One must understandblood 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 pressure1. Cholesterol gets deposited on arterial walls,causingnarrowing of arteriesand 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 asatherosclerosis.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 byrelaxing arteries or byreducing 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 inperpetuity.

Answer 2

The top number refers to the amount of pressure in your arteries during the contraction of your heart muscle. Thisis called systolic pressure. The bottom number refers to your blood pressurewhen your heart muscle is between beats. This is called diastolicpressure.
