For patients with physiological goiter, the swelling can generally subside within a few weeks of drug treatment, while for patients with pathologic goiter, the time for swelling to subside is relatively longer, and may take several months or even longer. If the swelling is caused by physiological factors such as thyroid hormone deficiency and compensatory hyperplasia of the thyroid gland, it can gradually subside in a few weeks after appropriate thyroid hormone supplementation under the advice of a doctor. If the patient’s goiter is pathologic, such as hypothyroidism or hyperthyroidism, thyroiditis, thyroid adenoma, etc., it is necessary to use the inhibition of thyroid function to carry out the treatment, and if necessary, surgical treatment can be carried out, and the recovery time is relatively longer, and it may take a few months or even more time. Patients with enlarged thyroid gland should go to the hospital in time to find out the cause and be treated accurately under the guidance of professional doctors.
