Thyroiditis is primarily divided into acute, subacute, and chronic types, along with some painless and postpartum thyroiditis. If it is acute or subacute thyroiditis, it is a self-limiting disease caused by viral infections, and there is no need to use drugs that adjust thyroid function. Treatment mainly involves the use of non-steroidal or hormonal medications, as well as drugs that control heart rate. If it is autoimmune thyroiditis, commonly referred to as Hashimoto's thyroiditis, it often presents with positive thyroid antibodies. In the early stages, thyroid function may be normal, but typically progresses to reduced thyroid function over time. When thyroid function tests reveal reduced thyroid function, timely supplementation of thyroid hormone levels can control this type of autoimmune thyroiditis within a normal range. Additionally, for painless thyroiditis and postpartum thyroiditis, particularly the latter, which is often related to the mechanism of postpartum immune changes, it primarily depends on whether thyroid function has changed. If there is no change in thyroid function, treatment is temporarily unnecessary. (Medication should be administered under the guidance of a doctor.)
