Specializes in Internal Medicine

Diet, meds and non specific bleeding from upper gi tract are commonly involved in changing stool color in black. Not all black stools are due to bleeding and black stools are not diagnostic for specific pathology, such as cancer. Your gastroenterologist or PCP would be best to place your findings in clinical context.
