What do they mean by black/tarry stools? - black stools

I had constipation, alternating between the nature of the class of smooth and soft stools for a few weeks, and sometimes the desire for a very dark brown. Well, when you say, absolute black on black stool mean? Since the chair was dark enough, but certainly not black, and it was not a hint of red or dark red in the stool. I have not really had cramps cramps not normal bathroom.

They say that information to a doctor immediately if you have a black chair, because it means bleeding of the gastro-intestinal tract higher. But you do not specify whether they refer only the latest black or dark stools.
