A reading of 90 mm Hg or less systolic blood pressure or 60 mm Hg or less diastolic blood pressure is considered low. In many instances, increasing blood pressure to healthy levels is a matter of treating the underlying cause of your hypotension, whether it's dehydration, medication, thyroid problems, diabetes or shock. When low blood pressure doesn't stem from another health concern and doesn't cause symptoms, it may require no treatment at all. Any effort to regulate your blood pressure must be overseen by your doctor.
Drink more water over the course of the day to stave off dehydration and increase blood volume. Have a cup of coffee or tea, as caffeine temporarily boosts blood pressure. Significantly limit or skip consumption of alcohol, which promotes dehydration and lowers blood pressure.
Add more sodium into your diet with your doctor's approval and supervision. Drink sports drinks with sodium and potassium, use more salt on your food or prepare recipes that call for soy sauce. Stick to a healthy diet that incorporates fresh fruits and vegetables, whole grains and fish.
Consider whether any medications or supplements you take cause lowered blood pressure as a side effect. Talk to your doctor about altering your dosage or finding a substitute treatment.
Avoid triggers and circumstances that lower your blood pressure. Stand up slowly and don't remain standing for too long. Keep your legs uncrossed while seated. Avoid frightening or emotionally stressful situations. Gradually increase the time you spend sitting up if you've been bedridden for a period of time.
Eat several small, low-carbohydrate meals every day if you suffer from a condition called postprandial hypotension.
Wear compression stockings on your legs if your doctor advises it. Use these elastic leggings to boost circulation in your lower body and prevent blood from pooling in your legs.
Consult your doctor about medications that can increase your blood pressure. Ask whether fludrocortisone, midodrine or other options might be of benefit for your particular type of hypotension.
