What happens to body during diarrhea? Especially the water part? Normaly, the water we drink is absorbed in the body and most part of thrown removing toxic elements via urine. But, during diarrhea body losses lot of water and we become dehydrated and weak. Suppose due to some process let’s say like Osmosis the water travels thru membrane and finally transforms into another substance, blood. So, during dehydration, does this process reverse? Why do we feel weakness? Also, when body knows it’s getting weak why it is still dehydration without absorbing any water? Someone please explain whole process.

There is a tube that runs through your body, everything you eat and drink goes through that tube. The tube is designed to break down all that food and absorb the nutrition and water from the food.

For various reasons you can get diarrhea which speeds up the process of expelling the contents of your digestive system, your body doesn’t have time to absorb all the liquid which is why the stool is a wet goopy mess and also why you become dehydrated, your body didn’t absorb the water from your intestines.

It’s not pulling water from your body so much as its not absorbing the fluids you consumed, which is critical to remaining hydrated.
