Reduced permeability of the intestinal cells prevents water from being absorbed.

Work Step by Step

When digestion is interrupted and the cells are irritated, the intestinal cells can't absorb as well. Their membranes have reduced permeability. This can be a method of keeping out the source of the irritation from entering the rest of the body. The reduced permeability reduces the amount of water that can be absorbed by the intestinal cells into the bloodstream. This allows watery stools to form, which is known as diarrhea.
