Whats Wrong with me if everytime...?

I lay down and get up, walk a couple steps and then my eyes black out, I have to stop walking and hold my balance for a few seconds until the blackness from my eyes fades away. My blood pressure is good, and I am hydrated. I am 16. Whats wrong with me?

I also get dizzy when this happens. I get close to fainting.

Are your taking prescription drugs? Or any drugs for that matter? Are you getting excercise & physical activity? It sounds like it might be ur diet. Really, try going for like 2-3 days eating just fresh fruit and vegetables, no pills or anything. And lots of water. See if that makes any difference, and if it does, then you might just have a vitamin defiecincy.

Also if you arent going to the bathroom regularly this will definately happen. I had this problem to when I was not going every day or more.
