How does your stomach determine when to throw your food back up? (Like for food poisoning or something) and how come it’ll digest the food but then you have diarrhea instead? If it was bad, shouldn’t you have thrown it up before it got to the intestines?

Commenting for the diarrhea bit:

Diahrrea is when your body throws up out your butt. This is why it’s mostly water. If your body detects an irritant or some other pathogen it will signal to have your body fill your intestines with water, flushing out whatevers inside. This is why diahrrea causes dehydration. Your body uses a large quantity of water to flush your guts out, so it doesnt have time to be absorbed by your intestines.
