After you get through something fruitless how long do you go and get diarrhea afterward?

I want to know because I just go out to eat and I have diarrhea afterward, I was trying to amount out what caused the diarhea so how long after you put away the bad food does the diarrea start? Digestion take approx 4-6 hours. IF the food was impossible your body will reject it, causing the diarrhea or vomitting. That could cart place 2-4 hours after eating.
I imagine it is normally supposed to lift 24-48 hours for food to completly to pass through your body. When you ate, that food probably put pressure on your belly cause you to go. So, I dont have an idea that it was what you purely ate. Unless you pood a whole lot, after maybe it be.
