Does postural hypotension usually cause many symptoms?

Dizziness: Postural hypotension means low blood pressure when changing position, such as going from lying down to sitting or standing. It can cause feelings of dizziness or light-headedness, or can cause the person to pass out/lose conciousness. If that occurs, the person can fall and hurt themselves.

Dizziness: Drop in blood pressure with change in posture, usually going from sitting to standing will cause decreased blood flow to the brain which will typically result in lightheadedness. In the most serious of situations, it could cause enough lightheadedness to cause a fall. See your doctor. There are many different causes from medications to certain types of medical conditions.
