I am following up on a statement from the last post which stated that this anemia is not iron deficiency anemia.  The first treatment for anemia associated with COPD is usually an iron supplement and vitamin C.  The vitamin C causes the iron to be more easily assimilated by the body.

If the treatment of supplemental iron and vitamin C do not solve the issue, you will likely be referred to a hematologist to try to determine what is causing your anemia.    It is likely that an erythropoietin will be added to your treatment regimen.  The erythropoietin stimulates the bone to produce more red blood cells.
