What is often a treatment for Addison's disease?

Corticosteroids are commonly used as a treatment for Addison's disease because this condition is characterized by insufficient production of certain hormones by the adrenal glands, particularly cortisol and aldosterone. Corticosteroids, such as hydrocortisone or prednisone, help to replace the hormones that the body is not producing adequately. This replacement therapy is essential for managing symptoms and maintaining normal bodily functions, including stress response, metabolism, and immune function.

The other treatment options listed do not address the hormonal deficiencies specific to Addison's disease. Insulin therapy is mainly used for diabetes management, antibiotics are used for bacterial infections, and a high-protein diet does not directly influence adrenal hormone levels. Therefore, corticosteroids are the appropriate and effective treatment for individuals diagnosed with Addison's disease.
