The word occult just means hidden. So occult blood in the feces means that it is there, but you might not see it. If a person tests positive for occult blood in their stool, it usually means there is internal bleeding somewhere. It could be from an ulcer, recent surgery, or cancer, among other possible causes. A doctor needs to determine the source of the bleeding whenever there is internal bleeding.
