Pernicious Anemia Definition
Pernicious Anemia develops when the body is unable to absorb the vitamin B12 it needs from food because of a lack of a protein, called intrinsic factor, produced by the stomach. Intrinsic factor is required for absorption of vitamin B12. Pernicious anemia is often associated with an autoimmune-mediated attack of parietal cells of the stomach and/or intrinsic factor. Anemia is the insufficient delivery of oxygen by red blood cells from the lungs to the cells of the body. The sooner pernicious anemia is treated, the better the outcome. If you suspect you have this condition, contact your doctor.
