What is high blood pressure

Everyone has blood pressure. it is only when it becomes high that it causes problems. Blood pressure is the pressure exerted by blood on the walls of the blood vessels when it pushes through them. High blood pressure or hypertension results when this pressure is more than the normal pressure. Hypertension is a dangerous condition as it affects nearly all parts of the body and can lead to many major diseases and conditions.

Normal Blood pressure and high blood pressure

The normal blood pressure is 120/80. This means the pressure on the walls is 120mm Hg when the heart pushes blood through the vessel and 80 mmHg in between two beats when the heart fills for the next push. The upper number in the fraction is called systolic pressure and the lower one diastolic pressure.

When these numbers rise, even when the diastolic remains at 80 and only the systolic is higher than 120, you will be diagnosed as hypertensive. High blood pressure damages your arteries, heart, brain, kidneys and eyes and can lead to life threatening conditions. There are various stages of hypertension and your risk increases as you progress to the higher stages.

Causes of high blood pressure or hypertension

Various factors contribute towards increasing your blood pressure. it is known that hypertension runs in families and that it affects more men than women. Changing your lifestyle and adopting healthy practices can help you decrease your risk of developing hypertension.
