High blood pressure, a condition in which blood flows through the veins and arteries in a higher than normal pressure, also known as hypertension, is a disease that is very common lately. When there is a pressure force that pushes the blood on the walls of the arteries, then there is high blood pressure. There are two different pressures: one systolic blood pressure when the heart beats while pumping blood, and the other – diastolic pressure, when the heart rests between beats.
The ranges of blood pressure include:
Prehypertension: 120-139 / 80-89
Stage 1 high blood pressure: 140-159 / 90-99
