Fainting upon standing, ALWAYS dizzy when standing?!
Question: Fainting upon standing, ALWAYS dizzy when standing?
Answers:
well for one i think it could be a mixture of your height and your age. if you are 6' 4", and only 14 that's a lot for your heart to be doing. the postural hypotension seems the most likely. i'm 6' 1" and get it from time to time as well. i would follow up with your doctor, they may want to do lab work to make sure everything is okay.
It is highly likely that you suffer from Low Blood Pressure.

you have a serious heart problem your heart isnt strong enough to pump blood to your brain with the force of gravity if taken care of when the symptoms start appearing they can be nipped and destroyed and have the problem go away but because you have waited so long you have probably done some irreversible damage that could keep you in a wheel chair/at risk of heart attack or stroke. go to the doctors immeadeatly you could be in serious danger if your hearts not strong enough to pump blood to your brain you honestly could die from a brisk walk.
