The smell of feces is caused by the action of bacteria such as sputum, skatole, mercaptan, hydrogen sulfide and the like. Examination of the special smell of feces can help to initially diagnose digestive diseases. For example, when the pancreatic disease, intestinal absorption is poor, the digestive tract is bleeding, and the colon (rectal) cancer is ulcerated, the feces have a sub-smelly smell. Amoebic enteritis has a fishy smell. When fat and sugar are digested or malabsorbed, the stool is abnormal due to acid odor caused by decomposition of fatty acid and fermentation of sugar.
