Hashimoto’s thyroiditis has normal thyroid function and usually does not cause protruding eyes. Hashimoto’s thyroiditis is an autoimmune disease that tends to go through a relatively long period of time from the onset of the disease to abnormal thyroid function, which may eventually lead to hyperthyroidism or hypothyroidism. However, only hyperthyroidism can lead to the formation of synostosis. Normally, Hashimoto’s thyroiditis has normal thyroid function and does not result in a protruding eye. If the thyroid function is normal in Hashimoto’s thyroiditis, it is recommended to go to the endocrinology department of a regular hospital, and cooperate with the doctor to conduct blood tests to check whether the thyroid function is suddenly abnormal. If the diagnosis of hyperthyroidism is confirmed, you should cooperate with the doctor to take anti-thyroid medication, such as methimazole or propylthiouracil, etc., and follow the doctor’s instructions for regular review, pay attention to monitoring the changes in thyroid function.
