AIBU to feel angry at how my dad is acting?

[ThisMustBeMyDream]

Currently on holiday abroad. My dad and his wife are with us.
Last night we went for dinner. I felt 100% fine. After the first mouthful of coke zero, I felt an intense pain of a trapped gas bubble from the drink. I fainted. This has happened twice before; same thing - pain causing vasovagal response. I also have low BP making me prone to fainting (I faint when local anaesthetic containing adrenaline is used for example).
Afterwards, once I came around I felt nauseous and shaky. This is the effect of low BP. I tried to eat some of my meal, but could not manage much as I just felt rubbish.
I went back to my room, lay down and felt much better very quickly. As it was 9pm, I decided just to call it a night and sleep.
This morning I am also fine.
As I say, this has happend twice before with pain of trapped gas in a fizzy drink causing me to faint.
My dad is insisting it is sunstroke. It is not. He will not listen, he is being rude, speaking over me, calling what I say as ridiculous basically.
I'm furious. He knows nothing of my medical history (minimum involvement in my life from age 9). I'm a HCP myself. I am fully aware of sun/heat stroke, and know full well I do not have it.
I am bloody raging at his dismissive attitude.
AIBU to feel so angry at what amounts to him treating his 34 year old daughter as a child?

When I say it has happened twice before - that is the trapped gas causing intense pain, causing me to faint.

Can you just ignore him and change the subject? He's obviously decided he knows more for whatever reason. Wrongly!

OP, why on earth you are on holidays with such an idiot is the real question?

Try and get through the holiday and don't do it again.

He sounds awful.
Take care.

Ignore him.

Stop drinking fizzy drinks.

You are not BU. I don't know why some parents insist on treating their adult children as if they were still 5.

I would use sarcasm on him and agree that he must know best. You could also point out that you are the HCP and that due to his minimal involvement in your life he knows FA about your medical history. Then tell him you have had enough of his mansplaining and stick your headphones on to drown him out.

Nobaggypants, it can happen with other drinks too. Twice has been fizzy, the other was with flavoured water. I can't not drink anything at all 🙈

Yes! Mansplaining is exactly how it feels!!

From what you’ve written, he doesn’t sound like he’s willing to listen to an explanation of why you know better than him. So you have two options.

Either ignore it completely and never go on holiday with him again, or treat him with as much contempt as he’s treating you with. If it comes up in conversation again, laugh at him. Say ‘oh here we go, Florence Nightingale has arrived to give me the benefit of his medical wisdom’. If he insists it is sunstroke, say ‘of course it is dad’ and roll your eyes.

The bigger person would do the first. Personally, I’d do the latter. I’m not big on being patronised.

Yes Dad, Im sure you're right Dad

But you aren't a nurse though?

Maybe he meant dehydrated rather than sunstroke- just got the terminology wrong.
Someone who has been in the sun that cannot drink easily - not unreasonable.

I'd agree it isn't sunstroke.

However a trapped air bubble from a single mouthful of fizzy drink-although it's also happened with non-fizzy drinks too? Doesn't sound any more plausible.

No Jessbow, he doesn't mean dehydrated I could drink, I just had intense pain from trapped wind essentially.

Just ignore him. Smile and nod. Don't go on holiday with him again.

I have had that happen with Coke Zero, but not with any other drink. The pain is intense like what I imagined a heart attack might feel like. I avoid Coke Zero totally Diet Coke is fine. Never any problems.

Witchend, the cause of it doesn't matter so much. Intense pain (from any source) can trigger a vasovagal response.
The fact mine comes from trapped wind amongst other things (adrenaline being another) is just a cause for the effect.
Have you never had painful trapped wind?
Also, if you google, it is an actual thing, although it tends to happen more frequently than it has to me.

I think you have to learn not to give a fuck what he thinks or says.
You’re giving him far too much power over your emotions. Adopt a breezy “ok dad whatever you say” and change the subject. He knows how to push your buttons so don’t let him.
