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?
In: Biology
When you eat and drink, various parts of the food are broken down and absorbed by different parts of the body, including water. The main place this happens is your intestines. If the food moves too slowly through the intestines, too much water will get absorbed, and you’ll have a hard, dry stool (constipation). If it moves too quickly, not enough water gets absorbed, so the stool will be watery (diarrhea).
If you’ve eaten something poisonous or diseased (or your body thinks you have), it will increase the speed to get the offending thing out as quickly as possible. This means your body doesn’t have the time to slowly absorb the water, so it gets flushed out with everything else.
And since your body isn’t absorbing the water (it’s moving too fast to do it), you’ll end up dehydrated unless you drink more water than usual to make up the difference.
