What is Blood Pressure? Causes & Symptoms

What is Blood Pressure

Your arteries carry blood from your heart to the body. Blood pressure is the measure of the force exerted by blood against your internal wall of your arteries. The propulsion of blood through the body obviously requires some pressure, but when it is too strong, you have high blood pressure, or hypertension.

Each reading of the measurement of blood pressure provides two different figures: eg. “120 and 80”, which is written as 120/80. This is because each beat of the heart sends a pressure wave that travels through the bloodstream. The highest number (the systolic blood pressure) corresponds to the sound emitted by the peak of the wave at the time of cardiac contraction. The lowest digit (one diastolic blood pressure) corresponds to the “trough” of the wave generated by the cardiac rest period.

b.p dThe numbers of blood pressure are always recorded in the same order, the systolic pressure before the diastolic pressure; these figures are for measuring the pressure in millimeters of mercury (mm Hg) on ​​the tonnage of a tensiometer. Any person whose measurement of systolic pressure is greater than 140, and the diastolic pressure at 90, has high blood pressure.


Hypertension is called primary (or essential) it has no obvious causes. Most cases of hypertension meet the criteria of essential hypertension.secondary hypertension starts due to  an underlying problem, such as kidney disease or hormonal imbalance causes hypertension.. When it is possible to correct the underlying cause, the level of blood pressure usually improves and may even return to normal.

Other predisposing factors for hypertension include:

Age (It rises with age), immoderate meal , Alcohol drinking, less  exercise, obesity, sleep apnea, the stress.

Symptoms and Complications:

It causes  headache, eyesight problems, dizziness &  breath shortness .Many People with hypertension do not observe any of these symptoms. So it is also known as ” SILENT KILLER”.
