why do we get diarrhea?

I mean why do many different causes result in your body reacting that way? What is the process? And is the liquid just the water you drank making it all the way through you, or is it secreted somewhere along the way?

As for why its WATERY: most of your water absorption happens in your large intestine. One of the last thing your body does after extracting all the nutrients it can out of whatever’s youve eaten/drunken, is to absorb a bunch of water out of what’s left. Your body needs that water, plus it means you have to stop to push out waste (poo) less often. But this process takes some time. So when your body freaks out for whatever reason and decides to take the “jettison all contents” route and get whatever is in your guts out ASAP, your poo doesn’t hang out in your large intestine long enough to dry out any appreciable amount. This is also why dehydration is such a big risk with extended diarrhea. Even if you’re drinking water you’re barely absorbing any of it. It’s also why your poo gets much harder and firmer if your GI tract slows down; it has that much more time to hang out in your con and dry out more.
