What Is the Normal Range for Diastolic Blood Pressure?
-
Blood pressure
-
The American Heart Association defines blood pressure as the pressure of the blood against the walls of the arteries.
Systolic Pressure
-
Systolic pressure is the measurement of the blood's force against the arteries as the heart pumps.
Diastolic Pressure
-
Diastolic pressure is the force against the arteries between beats while the heart is at rest.
High Blood Pressure (hypertension)
-
An individual is considered to have mild high blood pressure if her systolic number remains between 140 and 159 and her diastolic number remains between 90 and 99. A systolic number continuously running greater than 160 and a diastolic number greater than 100 is indicative of moderate to severe high blood pressure.
Low Blood Pressure (hypotension)
-
A systolic number continuously running less than 90 and a diastolic number less than 60 is indicative of low blood pressure.
Conditions That Affect Blood Pressure
-
There are a number of conditions that can cause blood pressure to fluctuate. Some examples are heart disorders, neurological disorders, kidney and urological problems, medications, infection and stress.
