Treatment depends on the case. Currently, there is no cure for Hashimoto's thyroiditis, and the main goal of treatment is to correct secondary thyroid dysfunction and reduce significantly enlarged thyroids. Generally, for patients with mild diffuse goiter without obvious compression symptoms and no thyroid dysfunction, no special treatment is needed; follow-up observation is sufficient.

For patients with significant thyroid enlargement and compression symptoms, treatment with levothyroxine may be used to reduce thyroid swelling. If the patient has hypothyroidism, thyroid hormone replacement therapy can be administered.

(Medication should be administered under the guidance of a doctor.)
