What is the reason of black colour blood?

Dr. Heidi Fowler answered

Specializes in Psychiatry

Melena.: Some medications can cause stool to become black. If stool is black, tarry and stinks to high heaven - this can be melena (gi bleeding). Please seek prompt medical attention if that is the case.
