How Dangerous is Low Blood Pressure

How Dangerous is Low Blood Pressure

 

 What is blood pressure?

 

The heart pumps blood throughout the entire body, and at the same time constantly adjust and balance our blood pressure to ensure all body parts receive enough blood and oxygen so that there is no danger from low BP.  This blood constantly exerts pressure on the arteries with every heartbeat. This force against the artery walls is called blood pressure.

 

A normal (or optimal) blood pressure is considered between 100/60 and 120/80 and can somewhat fluctuate throughout the day. The National Heart, Lung, and Blood Institute define low blood pressure (aka hypotension) as under 90/60 mm Hg.
