I black out when I stand up...why?!
Question: I black out when I stand up...why?
Answers:
Hello. That's odd that you mention high blood pressure, because i have low blood pressure, and the same thing happens to me. When i asked the doctor, he said low blood pressure causes that. Other people in my family have low blood pressure, and they feel faint ( and have actually passed out ), just by getting out of a chair. I make sure that i get up very slowly, instead of just jumping up, and that seems to help me. If you haven't already, you should probably see a doctor about this, because there are some medical conditions that can cause this to happen also, I found out i had Thyroid disease, and since taking medication for it, i rarely feel faint anymore. It can also happen from heart conditions. Not trying to scare you, but it's something that should be ruled out, Take care.
Vertigo or anemia i would guess.
