What is Dia in blood pressure?

What does the diastolic blood pressure number mean?

What Does the Diastolic Blood Pressure Number Mean? The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen. A normal diastolic blood pressure is lower than 80.

What does high diastolic pressure mean?
