DEAR MAYO CLINIC: I have normal systolic blood pressure, but my diastolic goes between 82 and 96 during the work day and goes down to normal at night or when there is no stress. Should I be concerned or is this normal?
ANSWER: If you don't have other health issues that increase your risk of cardiovascular problems, the situation you describe — isolated diastolic hypertension — isn't dangerous now. But it's not normal, either. People with elevated diastolic blood pressure often develop elevated systolic blood pressure over time. You can help prevent that by taking steps to lower your diastolic blood pressure to a normal level. — John Graves, M.D., Nephrology and Hypertension, Mayo Clinic, Rochester, Minn.
