Black stools Report

A black stool usually means that the blood is coming from the upper part of the gastrointestinal (GI) tract. This includes the esophagus, stomach, and the first part of the small intestine. Consuming black licorice, lead, iron pills, bismuth medicines, or blueberries can also cause black stools.
