Hashimoto’s thyroiditis cannot be cured and is an autoimmune disease because of elevated thyroid antibodies, thyroglobulin antibodies, and thyroid peroxidase antibodies, which automatically attack the thyroid tissue cells, repeatedly destroying the thyroid tissues and thus creating an empty shell of thyroid tissue, causing the destruction of the follicular cells of the thyroid gland, which produces and stores the thyroid hormones, and causing a synthesis and release of This causes a decrease in the synthesis and release of thyroid hormones, resulting in permanent hypothyroidism. According to the above mechanism, the final result of Hashimoto’s thyroiditis will become clinical hypothyroidism, because the destruction of thyroid follicles is irreversible, so Hashimoto’s thyroiditis itself does not need treatment, but if once combined with clinical hypothyroidism, it is necessary to take oral levothyroxine sodium tablets to supplement the thyroid hormone for life, and to check the thyroid function on a regular basis, and to adjust the dosage of the medication according to the results. Therefore, Hashimoto’s thyroiditis cannot be cured and requires lifelong treatment with oral medication.
