The causes of thyroiditis are mainly divided into several types:

The first type is acute thyroiditis, which is mostly caused by bacterial infection. Some abscesses in the thyroid lead to fever and inflammation of the thyroid. Generally, anti-infection treatment can achieve a curative effect.

The second type, subacute thyroiditis, is mostly caused by viral infections. It is a self-limiting disease that can be cured by using some analgesics, and even some hormonal medications.

Chronic thyroiditis generally arises from autoimmune diseases. Often in the late stages, it causes reduced thyroid function. Since currently there are no drugs to intervene in autoimmune diseases, the main treatment is medication maintenance and control of thyroid function within the normal range.

Therefore, the causes of thyroiditis need to be divided into acute, subacute, and chronic thyroiditis to distinguish its causes.

(The use of medication should be done under the guidance of a professional doctor.)
