PS: Years ago when my daughter and I went to a hemotologist group, we both saw different doctors in the group. My daughter has been dealing anemia for a long time. WISH she concentrated on more iron rich foods. She's gotten transfusions. She was a pretty sick gal for a lot a years when she was married and having babies, still born, miscarriage...long other story.

Anyway, one doctor said low ferritin can cause more fatigue, the other doc said it does not. Two differing opinions in the same group of docs... That has stayed with me for years.
