Blood pressure is the pressure of blood pushing against the walls of your arteries. Arteries carry blood from your heart to other parts of your body.
Your blood pressure normally rises and falls throughout the day.
Blood pressure is measured using two numbers:
The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats.
The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.
If the measurement reads 120 systolic and 80 diastolic, you would say, “120 over 80,” or write, “120/80 mmHg.”
A normal blood pressure level is less than 120/80 mmHg.
High blood pressure, also called hypertension, is blood pressure that is higher than normal. Your blood pressure changes throughout the day based on your activities. Having blood pressure measures consistently above normal may result in a diagnosis of high blood pressure (or hypertension).
