As long as you feel fine and your blood pressure is low naturally — and not because of too much medication to lower high blood pressure — all you need to do is count your blessings. You’re one of the lucky ones.
A blood pressure of 90 over 60 (the top number is called the systolic pressure, the bottom number the diastolic) is actually “normal for many people,” said Dr. Michael Jaff, director of the Vascular Diagnostic Laboratory at Massachusetts General Hospital.
In fact, pregnant women often have blood pressure that’s as low as 80 over 50 (because the body sends much of the blood flow to the fetus) and it does them no harm, said Dr. Richard Karas, director of the Preventive Cardiology Center at Tufts-New England Medical Center.
But many people have low blood pressure because they’re dehydrated. You can remedy this by drinking more fluids and adding salt to your diet. (People with high blood pressure should not add salt.)
Although low blood pressure is not dangerous if you feel fine, you should see a doctor if you have low blood pressure and lots of headaches, often feel dizzy when you stand up or have foggy vision. Low blood pressure plus chest pains, or shortness of breath or fever also mean you should contact a doctor.
