Hashimoto’s thyroiditis does not require special treatment when the thyroid function is normal and the clinical symptoms are not obvious, and regular checkups are sufficient; it does require treatment when the thyroid function is abnormal, the thyroid gland is enlarged, and there are symptoms of compression. Hashimoto’s thyroiditis, also known as chronic lymphocytic thyroiditis, is an autoimmune disease. For patients with no obvious symptoms and normal thyroid function, there is no need for special treatment, as long as the thyroid function is checked regularly, and dietary attention is paid to appropriate iodine restriction to avoid consuming iodine-rich foods such as kelp, purslane, and seafood. If Hashimoto’s thyroiditis is combined with hypothyroidism, you need to take levothyroxine sodium tablets as a replacement therapy, especially if you are planning to get pregnant or are already pregnant. If Hashimoto’s thyroiditis is associated with significant enlargement of the thyroid gland, with symptoms of pressure that cause breathing difficulties or aesthetic problems, or if malignant tumors of the thyroid gland are suspected, surgery may be required. Hashimoto’s thyroiditis requires prompt consultation with an endocrinologist.
