Why Do Humans Get 'The Runs' When They Travel?

Travelers' diarrhea happens when your body doesn't know what to do with new food. When you're at home, your stomach gets used to eating the same things every day, like pizza or tacos. But when you travel, you might eat something strange, like a spicy soup from another country. Your gut isn’t ready for it and gets confused, so it moves everything through your body faster than normal, that’s how you get the runs!
