Is Hashimoto's hyperthyroidism severe, and how is it treated?

Hashimoto's hyperthyroidism is severe and requires treatment with medication or surgery. Hashimoto's hyperthyroidism refers to a condition in which a patient simultaneously has both hyperthyroidism and Hashimoto's thyroiditis. Initial treatment typically involves antithyroid medications, primarily propylthiouracil and methylprednisolone, which are effective in promoting patient recovery. However, if the patient's condition is severe, it is recommended to promptly go to the hospital to determine the exact cause and receive appropriate treatment accordingly.
