(HealthDay News) -- High blood pressure gets all of the attention, but very low blood pressure can be just as dangerous, experts say.

If severe enough, low blood pressure (hypotension) can lead to dizziness and fainting.

The U.S. National Heart, Lung and Blood Institute offers these suggestions for dealing with low blood pressure:

• After you've been sitting or lying down for an extended period, stand up slowly. Also, change the position of your legs before you stand.
• Eat frequent, small meals that are low in carbohydrates.
• If your doctor mentions that you have neurally mediated hypotension, avoid standing for long periods. If you must stand for a long time, wear compression stockings and walk around frequently.
• Drink sports drinks that contain sodium and potassium, or water, throughout the day.
• Try to avoid scary or upsetting situations.
