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.

Diarrhea can start higher up with an early reaction to unwanted food or a viral infection. In that case you might empty your gut from both ends.

Or it can start lower down, to correct constipation. Poop has built up in your colon and is not moving fast enough, so your body decides to flush it by pumping water into the colon to soften it up, and then expelling it.
