Fainting-like sensation/symptoms... low blood pressure? why?!
Question: In the past month, this has happened about twice a week, but not even a year ago it was only every couple of months. This started about three years ago (at age 15)
It usually happens after I stand for a while (15-30min) (lately it's taken even less time) (but usually its only when I'm casually walking or standing still - not when I run or work)
-vision fades until black
-hearing is muted (sounds exactly like when you plug your ears with your fingers)
-sweating
-can't feel my pulse, but I can feel my heart beating faster (low blood pressure & heart is trying to compensate?)
-headache
I'm 18 yrs old, 5'5", 130 lbs, eat like a pig and have added more salt to my diet to maybe prevent this. I exercise regularly (run about 2 miles 3 times a week, bike 30-40 miles on weekends). I've never had an eating disorder, never drunk, never been on drugs.
Only once I actually fainted, the other times I caught myself and sat down before it knocked me down.
Thanks so much!!

it sounds like what you have is vasovagal or neurocardiogenic syncope. Essentially this means that the nervous system reflexes that are responsible for maintaining your blood pressure are not working normally. There are tests to confirm this diagnosis(tilt table) and a variety of different treatments including medication. Get this evaluated before you fall down and hurt yourself.
Could be dehydration. Could be something you need a full work-up to find the answer to.
I agree with Lisa above.
I also think you are wearing your body out with too much exercise.
While your at the doctors make sure they check your kidney function out.
