Treatment depends on the cause of B12 deficiency anemia.
Many people may need these shots once a month for the rest of their life. The shots may no longer be needed after Crohn's disease, celiac disease, or alcoholism is properly treated.
Treatment for this form of anemia is usually effective.
Any damage to nerves may be permanent, especially if treatment is not started within 6 months of when the symptoms begin.
Vitamin B12 affects cells that form the outer surface of the body and line inner passageways (epithelial cells). Therefore, a lack of B12 may cause a falsely abnormal Pap smear.
Call your health care provider if you have any of the symptoms of anemia.
