Postural hypotension: If this happens when you stand up it might be from low blood pressure where the blood doesn't get sufficient supply to the brain and it can cause you to pass out. Blood pressure is a vital sign and is thus very important. See your md and get a diagnosis. You wouldn't want to fall and hurt yourself from this condition!
