Low Blood Pressure (Hypotension)

Optimal blood pressure is generally defined as 120/80. Low blood pressure (hypotension) generally refers to numbers less than 100/60. Low blood pressure is rarely a problem and in most cases it is beneficial. Studies show that the lower your blood pressure, the lower your risk of cardiovascular disease. Low blood is only a concern if you have symptoms such as dizziness, weakness, fatigue, or palpitations.

Many people with normal (or even elevated blood pressure) occasionally experience a temporary drop in blood pressure upon rising quickly. This form of low blood pressure, called orthostatic hypotension, may cause you to feel momentarily faint, or light-headed, but quickly passes. If you experience orthostatic hypotension frequently you may want to take precautions against falling, such as getting up more slowly and holding on to a support.

Low blood pressure can be caused by certain medications or treatable diseases. If you have symptoms of low blood pressure, such as dizziness, weakness, and fatigue, you should be sure to talk with your doctor about other possible causes.
