Would love to read how you might distinguish pernicious from "simple" anemia. Doc in FL determined pernicious based on low hemoglobin. Here at The Hotel California docs concluded that I am no longer because lab results show normal B-12 in blood samples. Can simply eating (like a maniac, force feeding after virtual starvation over several years) suddenly bring someone out of anemia (any form)? That blood draw was less than one week after admission, or roughly 30,000 calories later. (Crazzzy...)
