Does Thyroid Disease Cause Hives?

Thyroid disease itself is not a common cause of hives. However, there can be an association between thyroid disorders and certain skin conditions, including urticaria, which is the medical term for hives. Urticaria is characterized by the sudden appearance of raised, red, and itchy welts on the skin.

In some cases, thyroid dysfunction may indirectly contribute to the development of hives. For example:

  • Autoimmune Thyroid Disorders: Conditions such as Hashimoto’s thyroiditis (hypothyroidism) and Graves’ disease (hyperthyroidism) are autoimmune disorders. Autoimmune conditions involve the immune system attacking the body’s own tissues. While the primary target is the thyroid gland in these cases, it’s possible for autoimmune processes to contribute to skin-related symptoms, including hives.
  • Thyroid Medications: Some medications used to manage thyroid disorders, such as levothyroxine for hypothyroidism or antithyroid medications for hyperthyroidism, may rarely cause allergic reactions or skin-related side effects in some individuals. This could include the development of hives.

If you are experiencing hives or skin-related symptoms and suspect a connection to your thyroid health, it is essential to consult with a healthcare professional. They can conduct a thorough evaluation, including thyroid function tests and an examination of other potential causes for hives. Allergic reactions, infections, and other medical conditions can also lead to the development of hives, so a comprehensive assessment is crucial for accurate diagnosis and appropriate management.
