I often black out when standing up and legs/arms fall asleep very fast---what can cause this?
A doctor has provided 1 answer
Black out: Postural hypotension is when blood pressure drops upon standing, hence less blood flow to brain, hence fainting. Several things can cause that, from medications to blood diseases to neurological or vascular factors. Recommend appointment with your primary care doc. To explore those.
