After total thyroidectomy, although there is no more Hashimoto’s thyroiditis, the symptoms of hypothyroidism are still present and therefore still need to be treated. Hashimoto’s thyroiditis usually does not need to be removed by surgery, but because the enlarged thyroid gland can compress the anterior cervical region and lead to symptoms of dyspnea or dysphagia, or the thyroid gland has suspicious nodules that may be cancerous, then it can be treated by surgical resection, and after total thyroidectomy, the patient will lose the full function of the thyroid gland and aggravate the symptoms of hypothyroidism. Therefore, after total thyroidectomy, patients with Hashimoto’s thyroiditis should be treated with replacement therapy by taking thyroxine tablets and levothyroxine tablets. If you are diagnosed with Hashimoto’s thyroiditis and have undergone total thyroidectomy, please follow the doctor’s instructions. If you experience any discomfort, please seek medical attention.
