Whether thyroiditis can be cured depends on different situations. Subacute thyroiditis is a type of thyroiditis clinically characterized by neck pain and fever, which tends to heal on its own, meaning it can return to normal by itself. However, due to its symptoms of pain and fever, symptomatic treatment can be administered to improve symptoms. Acute suppurative thyroiditis is mainly a type of bacterial inflammation, and most patients can be cured with proper anti-infection treatment. However, more commonly seen in clinical practice are autoimmune-related thyroiditis, such as Hashimoto's thyroiditis, which generally cannot be completely cured. Yet, with proper and long-term medication, thyroid function can be restored to normal and can maintain a stable state for a long time without significantly affecting health.
