To ask if someone people pass out more easy then others

[Poseforme]

Or is just a human set thing that everyone would pass out under certain conditions

My husband's cardiologist said that some people are more prone to it than others. It was 3 years ago though and i can't remember why that was. It was in the context of her asking whether he faints often and he has fainted at least 4 times in his life whereas I never have. Honestly it was a fascinating conversation but I've forgotten most of it now, hopefully a medic can enlighten us.

Pass out as in faint or pass out drunk?

I used to faint a lot up until my 30's. I've not fainted for a while.

I had a period in my early 20s when I fainted a few times. Just got too hot and I was on the floor! Didn't happen when I was a child or now as a middle aged adult.

I was pretty skinny back then, maybe that had an effect!

Some definitely are more prone to it
eg/ with low blood pressure

I think if you have low blood pressure it might make you more prone to it. I had several dizzy/almost fainting spells in the shower when pregnant which the midwife put down to my naturally low blood pressure.

The only other time I’ve come close to fainting was at college whilst watching a dissection being performed on a horse’s leg (just the leg, the rest of the horse was not there!). I distinctly remember thinking to myself “Wow, this is fascinating” before everything started going blurry and black and having to be helped out into the fresh air by a classmate.

My mum often tells me about the time she fainted watching an episode of “Jimmys” (think it was a hospital documentary in the 80s when I was a small child).

I have low blood pressure. I believe it makes me more prone to fainting.

There is a condition called vasovagal syncope, basically fainting when your body overreacts to certain situations with sight of blood being the most common. Myself and DS both have this associated with pain - if we hurt ourselves in a sharp sudden way (like banging your funny bone that kind of thing) we can faint, it’s quite annoying.

I have low blood pressure and have fainted lots more in my life than DH, who has normal blood pressure. Only anecdotal, but it makes sense.

Another low blood pressure person here, and I pass out every time I vomit, and any semi significant blood loss will have me on the floor. Not squeamishness- just a physical response. I’m prone to vasovagal episodes.

Friends dd has this. Odd thing is the kids an elite gymnast, no fear, bangs herself around, no stranger to falls, pain, blood etc.

but stick a needle in her and down she goes.

i have low blood pressure and if not careful faint after giving blood. Once I realised it’s a simple matter of drinking enough and salty snacks.

I too am like those fainting goats due to vasovagal syncope, I’m much better than I was in my twenties but sharp pains or vomiting I’m spinning to the floor…..

Why two threads OP?

Think its an evolutionary quirk that some people faint at sight of blood or needle, because on the battle field it would lead to slower blood loss and more survival.
