In general, diastolic blood pressure is considered to be low if it is 60 millimeters of mercury or less. Normal blood pressure varies from one person to another though. If your diastolic blood pressure is consistently below 60 millimeters of mercury, but you aren’t experiencing any problems from it, you may not need to do anything.
If your blood pressure is high or low, you usually need at least three more blood pressure tests, spaced a week or so apart, to determine if you need treatment. Blood pressure can vary from moment to moment and day to day.

A drop of 20 millimeters of mercury (mm Hg) in the top number (systolic blood pressure) within 2 to 5 minutes of standing is a sign of orthostatic hypotension. A drop of 10 mm Hg in the bottom number (diastolic blood pressure) within 2 to 5 minutes of standing also indicates orthostatic hypotension. Blood tests.
