Disease causes: such as irritable bowel syndrome, mostly related to emotions, may have diarrhea and constipation alternately, bowel sounds and other symptoms; enteritis, mostly with a history of unclean diet, may have diarrhea, abdominal pain and other symptoms; amebic dysentery may have jam-like stools; such as intestinal masses may have lethargy, anemia, blood in stools and other conditions.
