Why High Blood Pressure Is Dangerous

Blood pressure is the pressure exerted by the heart via the circulating blood on the arteries. Hypertension happens when the pressure is above normal. Hypertension is a silent and slow killer. It causes damages and increased wear/tear on various parts of your body - blood vessels, brain, kidney, heart, eye, and liver. Heart pumps blood to every part of the body delivering oxygen and nutrient. If the blood pressure is high, it would increase wear/tear and cause problems to your heart, arteries, brain, kidney, liver, and eye. We will discuss some of the problems which can be the result of hypertension.

See hypertension risk chart on how high blood pressure can increase the risk of obtaining cardiovacular diseases.

Hypertension significantly increases the risk of having health complications. This is something to be taken seriously. When blood circulates throughout the body under abnormal pressure, the weakest link is the one that would have problem first and there is no telling which one it is.

Heart muscle. To generate higher blood pressure, the heart has to work harder to circulate blood throughout the body. The extra load causes the heart muscle to enlarge, which eventually would weaken the muscle and reduce its effectiveness. An enlarged heart with weaken muscle would have increasing problem pumping sufficient blood and may lead to heart failure and heart attack.

Blood vessels. Blood vessel expands and contracts as the heart beats. This motion helps to distribute the blood and also to circulate blood back to the heart. High pressure would make the walls of the arteries to lose its elasticity and become less flexible. This would weaken the blood vessels and its ability to deliver blood.

Congestive heart failure. With weaken heart muscle and stiffer arteries, the heart is not capable to deliver adequate blood to satisfy the body's need causing congestive heart failure and heart attack.

Stroke. When a blood vessel bleeds inside the brain, this would result in insufficient supply of blood to the brain resulting in a stroke.

Eye vision. Hypertension can cause blood vessels in the eye to rupture or bleed causing blurred vision or even blindness.

Kidney failure. The primary function of a kidney is to maintain proper and electrolyte balance, filter the blood of metabolic wastes, and regulate acid-base concentration. High blood pressure narrows and thickens the blood vessels inside the kidney reducing its effectiveness. The kidney would process less fluid. Waste and fluid would build up inside the body, which would in turn cause the blood pressure to increase. Also the kidney has to work harder. Eventually the kidney will fail.

Others. There are many other diseases directly or indirectly linked to hypertension.
