Is my thyroid problem an autoimmune disease??

Thyroid disorders such as hypothyroidism and hyperthyroidism are also most often due to autoimmune diseases in the United States (Hashimoto thyroiditis and Graves disease). However the actual autoimmune aspect of this is often undiagnosed, particularly with hypothyroidism.  In individuals with an autoimmune thyroid disorder, the incidence of other autoimmune diseases is between 10 – 15%.  This means that these individuals are more likely to have an additional autoimmune disease such as rheumatoid arthritis, systemic lupus erythematosus (commonly known as Lupus or SLE), Celiac disease, and vitiligo - http://tinyurl.com/mesq3dg.  Autoimmune diseases are much more common in females, and are one of the top 10 causes of death in women up to 64 years of age (American Autoimmune Related Diseases Association, Inc).
