Guide To The Most Common Autoimmune Diseases

Pernicious Anemia

Most individuals have heard about anemia, but some may not realize that there are many types of anemia. One of these is pernicious anemia. This is an autoimmune disease that causes the patient's immune system to attack cells in their stomach that produce intrinsic factor. The result means that the patient's body cannot absorb vitamin B12. Vitamin B12 is crucial, as it allows an individual's body to produce healthy red blood cells, which are essential for proper body functioning.

Reports indicate that pernicious anemia is the cause of up to fifty percent of anemia from a vitamin B12 deficiency. Unfortunately, the cause of pernicious anemia is not known. Evidence suggests, however, that it is more common in individuals with a family history of the condition, in women around sixty years old, and patients with other autoimmune diseases. Thankfully, this condition can be easily treated with oral vitamin B12 supplements and vitamin B12 injections.
