Why do I blackout when I stand up?
I don’t mean blackout as in pass out, but sometimes when I stand up from lying down, I get really dizzy and my vision goes black. It passes 8–10 seconds later and I continue on my merry way, but this has been happening to me at least 1–2 times a day. I have a feeling it has to do with blood circulation and/or blood pressure. I am hypoglycemic, but keep myself hydrated and well fed to manage it. I want to know if this is something more medical or if it happens among many other people. Is it your body trying to adjust from lying horizontally to suddenly standing vertically?
What the hell, man?
