Feces is the common name for stool, some of which is reabsorbed, but not all. The main components of stool include water, food debris, bacteria, bacterial metabolites, and digestive tract mucosal detachments and secretions. What is most readily absorbed when stools remain in the intestines for a longer period of time is the water in the stools, while the dietary fiber, sugars, proteins, and other lipids contained in the residue are generally not reabsorbed. It is possible for these metabolites to continue to be absorbed when the body is under extreme starvation and holding the stool, but absorption is extremely low for stools that are about to be expelled from the anus. Other bacteria, bacterial metabolites, and residues that cannot be utilized by the body, such as mucosal detachments from the digestive tract, are also generally not reabsorbed. Therefore, some of the components of the stool will be absorbed by the body, but the vast majority will be excreted so as not to increase the burden on the intestinal tract.
