What might happen if your large intestine stopped absorbing water?

The body will experience constipation, will lack the necessary nutrients, and will be poisoned. Water or fluids are necessary for the proper movement of materials in the bowels; without it these debris will be stuck and the intestines will work harder causing bloating and upset stomachs. The lack of water in the large intestine will also inhibit the absorption of necessary nutrients that were released from food. As a result, the body will be deficient with many nutrients and will most likely create different complications. 

If this continues to happen for a longer period of time eventually the body will be poisoned because excretion of waste will also be hampered when fluids are not absorbed by the intestines.
