Blacking out and getting dizzy?

Question

I've been blacking out and getting dizzy for about 1 1/2 to 2 years now but it's gotten dramatically worse since i've been dieting. Every time i get up, i can't see for at least 10 seconds and if i get up in the middle of the night, i can't see for about 30 seconds. I diet but i keep myself healthy, nourished, and never deprived. plz tell me what's causing this and what i can do about it. Oh ya, i'm 14 years old.

I am a CCMA

You need to see the following specialists

Neurologist to rule out tumor or other brain conditions

Ophthalmologist NOT a Optometrist and Ophthalmologist

There are eye conditions that will actually cause you to black out

Answer 5

i know u say u arent depriving urself, and maybe ur getting enough food, but not enough calories. maybe eat food with more calories because it sounds like ur not getting enough nutrition

Answer 6

Under eating can cause blacking out and getting dizzy.

If you are not under eating and if your blood pressure is below 90/60 then it is probably low BP.  Feeling faint and actual fainting spells and dizziness are common symptoms of low BP so that could be the problem.
