Stool odor is the smell associated with stools, or bowel movements. Stools normally have an unpleasant odor. Stools are formed in the large intestine (colon), which is part of the digestive system.
Black stool that is tarry in texture and foul smelling is often a symptom of upper gastrointestinal bleeding from the esophagus, stomach or small intestine. This is called melena. Rectal bleeding of bright red blood with clots, sometimes mixed with stool, is called hematochezia.
