If no other cause for your anemia can be determined a short trail off Prilosec could be considered. However I certainly would look for other potential causes first. Since you have GERD perhaps you are loosing some blood through the gastrointestinal tract. Obtaining stool specimens and checking for occult blood can identify this. Hemoglobin levels in the 8-9 range can definitely cause a variety of symptoms such as fatigue, exercise intolerance, headache etc.
Treatment is warranted.
