I mean i get why very sick or wounded people faint, but what mechanisms cause healthy people to faint when they are super scared or excited?
In: Biology
I have a condition called Dysutonomia. It is a dysregulation of my autonomic nervous system. I’ve been going through the exclusionary diagnosis process for six years and I still don’t have a perfect diagnosis. This is what I can share from my experience: dysautonomia is directly related to blood pressure issues. It seems to stem from a vasovagal response. Meaning that there’s some kind of weirdness happening with the vagus nerve that runs from the base of your skull to your belly. The vagus nerve controls many of your autonomic systems (breathing, heart rate, digestion, sight, hearing, balance) so once there’s a disturbance to this nerve, all hell can break lose. I’m 39, AFAB, 5”7’, 125 lbs and by all considerations healthy. But if someone jumps out from behind a door, I collapse, can’t talk, can’t move, and just have to wait until my systems come back on line. AMA
