Risk Factors And Causes Of Pernicious Anemia

Pernicious anemia is best characterized as a condition where the body is unable to produce enough healthy red blood cells due to an insufficient amount of vitamin B12. This disease is considered an autoimmune disease, which is where the body uses its immune system to attack and damage its own healthy tissues. In this case, the immune system targets the intrinsic factor or a protein the stomach makes that is needed to absorb vitamin B12.
