Other causes are more insidious and include things like autoimmune diseases and parasitic infections. Usually, medical conditions that cause vitamin B12 deficiency involve problems with absorbing nutrients properly. Get to know what can increase an individual's risk of a vitamin B12 deficiency now.
Graves' disease is an autoimmune disease in which the immune system attacks the thyroid gland. It causes hyperthyroidism, which negatively affects virtually every organ system in the body.

Autoimmune diseases, in general, are associated with a vitamin B12 deficiency. This disease is just one of many autoimmune diseases; others include lupus, ulcerative colitis, and Crohn's disease.
