High Blood Pressure

What is blood pressure?

The pressure of your blood against the inner walls of your arteries as it is pumped around the body by your heart is blood pressure.

The flow of blood in your arteries and your blood pressure falls and rises, as your heart pumps, in a regular wave pattern. Blood pressure falls when your heart relaxes (diastole) and peaks when your heart pumps (systole).

Hypertension or high blood pressure can lead to serious health problems, such as a stroke, a heart attack, kidney disease or heart failure.
