Subacute thyroiditis is short for subacute thyroiditis, which is a self-limiting disease with a good prognosis. Mild patients only need to apply non-steroidal anti-inflammatory drugs, such as aspirin, ibuprofen, etc.; medium and severe patients can be given prednisone to relieve thyroid pain. Propranolol may be given for thyrotoxicosis; levothyroxine may be given for transient hypothyroidism. Subacute thyroiditis is a self-limiting form of thyroiditis associated with a viral infection that is curable in the vast majority of cases and usually leaves no hypothyroidism. Subacute thyroiditis patients need to go to a regular hospital endocrine consultation, under the guidance of a professional physician for standardized treatment, so as not to delay the condition.
