Heart diseases is one of the principal reason of death worldwide, and persons who have unusually high pressure in their arteries are more probable than others to die too early of heart disease. Blood pressure is a gauge to measure how hard the blood drives against the barrier of arteries as it moves throughout the body. In general blood pressure slightly goes up and down during the day, but if it stays up continuously, than you have high blood pressure. Generally high blood pressure is also referred as hypertension. High blood pressure (HBP) is very severe disorder that can result to heart failure, kidney failure, coronary heart disease, stroke and other serious health problems.
"Blood pressure" is the force of blood approaching against the boundaries of the arteries as the heart pumps out blood. If this pressure increases and remain high over time, it can harm the body in loads of ways.
Blood pressure consists of two numbers:
The systolic number explains how hard the blood move forward when the heart is pumping.
The diastolic number explains how hard the blood pushes among heartbeats, when the heart is calm and filling with blood.
Normal systolic pressure is 120 and a diastolic pressure is 80 and it is written as pressure of 120/80 mm Hg, or "120 over 80." High blood pressure is 140/90 or higher. Adults should have a blood pressure under 140/90 mm Hg. Lots of persons fall into the group called high-normal (130–139/85–89). People with high-normal blood pressure have to make lifestyle modifications to bring the blood pressure down and prevent high blood pressure. High blood pressure in adults is explained as a constantly elevated blood pressure of 140 mm Hg systolic and 90 mm Hg diastolic or higher.
