My vision goes completely black and I get super dizzy upon standing, why?

Posted , 3 users are following.

Sometimes when I stand up my vision will go completely black for about 5-10 seconds and comes back gradually and I get really dizzy and I can't seem to find out why. I'm anemic and I think that might have something to do with it, but I'm not sure. If anybody knows what this is and what causes it please help me out and let me know.

    standing up quickly can cause black out vision. i have same issue. it takes time for the blood to balance out when standing. standing up slower is helpful. nothing serious in most cases.
