Association Between Alopecia Areata and Thyroid Dysfunction

This document discusses the relationship between Alopecia Areata, an autoimmune disease causing patchy hair loss, and thyroid dysfunction. While the exact cause of Alopecia Areata is unclear, it is believed to be linked to autoimmunity and stress and affects 0.1-0.2% of the population. The condition can result in varying patterns of hair loss and may be temporary or permanent. The article highlights that Alopecia Areata is often found in conjunction with autoimmune disorders such as thyroiditis, celiac disease, and lupus erythematosus. Specifically, a strong association is noted between Alopecia Areata and patients with Hashimoto thyroiditis and hypothyroidism, suggesting a significant link between thyroid dysfunction and this form of hair loss.
