I have a hematologist. He doesn’t seem to care as to the “why”. I am getting iron infusion. My RBCs are above normal, compensating so bone marrow is not the issue. I produced more than normal RBCs. Retic count is high. And RDW. So must be many immature cells. Liver enzymes and bilirubin normal so there is not hemolytic anemia. Just not storing or absorbing iron or using too much to produce all those immature RBC. I eat a very healthy diet. I am going for an endoscopy and colonoscopy again. Had one last year and was normal. Not sure what else to do.
