Risk Factors Associated With A Vitamin B12 Deficiency

Atrophic Gastritis

Atrophic gastritis is yet another autoimmune disease associated with vitamin deficiencies, particularly of vitamin B12. It involves the immune system attacking the mucous membrane of the stomach, leading to inflammation and a lack of digestive fluids and enzymes. The stomach then cannot fully digest food. One of the substances the stomach is unable to make enough of in atrophic gastritis is a protein called intrinsic factor. In a normally functioning stomach, this protein is essential for the ability to absorb vitamin B12. Therefore, vitamin B12 deficiency is a common problem for patients who suffer from atrophic gastritis. Symptoms of vitamin B12 deficiency may even be among the first symptoms of atrophic gastritis. Injections of vitamin B12 are sometimes used as treatment.
