There is no cure for Hashimoto’s thyroiditis, and symptomatic treatment is usually used, with less iodine-containing foods. If the thyroid function is normal and the clinical symptoms are not obvious, there is no need for special treatment and regular checkups are sufficient; if the thyroid function is abnormal, the thyroid gland is enlarged or painful, and there are symptoms of pressure, treatment is needed, such as thyroid hormone replacement therapy, surgery, and so on. Hashimoto’s thyroiditis is an autoimmune disease, and there is no treatment for the cause of the disease. Symptomatic treatment is generally used to improve symptoms, reduce goiter, and prevent or delay the onset of hypothyroidism. Eat less iodine-containing foods, such as seafood, kelp and nori. If the clinical symptoms are not obvious and the thyroid function is normal, usually no treatment is needed and follow-up observation is sufficient. For patients with hypothyroidism, hormone replacement therapy is needed, and levothyroxine sodium tablets are commonly used clinically, and the thyroid function needs to be rechecked regularly. If there is significant or painful enlargement of the thyroid gland, or the presence of cough, dysphonia and other symptoms of compression, surgical resection can be considered. Patients with Hashimoto’s thyroiditis should seek prompt medical attention and be treated under the guidance of a doctor.
