“Blood pressure” is the force of blood pushing against the walls of the arteries as the heart pumps blood. If this pressure rises and stays high over time, it can damage the body in many ways.
Blood pressure is measured as systolic and diastolic pressures. “Systolic” refers to blood pressure when the heart beats while pumping blood. “Diastolic” refers to blood pressure when the heart is at rest between beats.
The table below shows normal blood pressure numbers for adults. It also shows which numbers put you at greater risk for health problems.
