Hello,
Low hemoglobin is not responsible for fatigue and black tarry stools.
In fact black tarry stools are due to bleeding in the upper gastrointestinal tract (GIT).
Bleeding from upper GIT causes black tarry stools and the upper GIT bleeding leads to anemia or low hemoglobin levels.
Anemia or low hemoglobin level is responsible for fatigue.
Thus, examination of upper GIT is required to know the cause of bleeding.

Thanks and take care
