Will a 10-day overstay in Thailand due to food poisoning negatively impact me?

Can overstay , just pay fine. You will be ok. Take care of youself.

Take 3 carbon tablets on an empty stomach, dont eat.

Wait 3 to 4 hours..

Then take take 2 imodium tablets.

You will be right as rain.

10 days overstay for food poisoning is laughable, in especially immigrations eyes.

I would suggest reducing the amount of overstay fines in your passport as much as possible.

Lazy ideas of having an excuse for overstaying and seeking any forgivness for it, is not good.

It is not school.

500 bht every day late they may stamp passport late stay and can arrested on way to airport best is get letter from hospital

500 THB daily penalty is one thing, the prospect of being arrested and deported for being illegally in the the country (although rare but happens from time to time) the other. Food poisoning is usually a matter of 1 or 2 days !

500b overstay a day
