Black stool: Unless you're taking iron supplements or peptobismol, I would recommend having your stool checked for occult blood which can be done in a physician's office very easily or by bringing a stool sample to a laboratory if your physician prefers not to examine you. Black stool can signify bleeding from the upper gastrointestinal tract.
