vitamin b12 from the food the body uses a protein called intrinsic factor which is released in the stomach by the cells. Vitamin B12 bound with intrinsic factor is absorbed in the last part of small intestine and when stomach fails to produce enough intrinsic factor the intestine is unable to absorb vitamin b12 which leads to Pernicious anemia. The malfunction inn stomach can happen due to weakened stomach lining and can also be caused when the immune system of body starts attacking the cells which are behind the formation of intrinsic factor. Pernicious anemia can also happen due to family history of diseases or the patient has a medical history of autoimmune endocrine disorder.
