What Are The Types Of Thyroiditis?

De Quervain's Thyroiditis

De Quervain's thyroiditis occurs when a virus or bacteria causes the thyroid gland to become damaged and inflamed. Gram-positive bacteria, adenovirus, coxsackievirus, Epstein Barr virus, echovirus, influenza virus, mumps, and enterovirus are known to produce this type of thyroiditis. In this form of thyroiditis, the patient's thyroid gland enlarges rapidly and becomes increasingly painful. At first, the damage done to the thyroid tissues allows for large quantities of hormones to leak into the blood, producing conditions of hyperthyroidism. However, this form of thyroiditis produces conditions of hypothyroidism shortly after the spike in blood thyroid hormone levels. This malfunction occurs because the damaged thyroid tissues cannot perform their function of iodine uptake, which is a compound required for the gland to produce thyroid hormones. Most cases of de Quervain's thyroiditis resolve successfully if the patient has had proper treatment. However, some patients may remain in a persistent state of hypothyroidism for a long duration after the thyroid inflammation has been resolved.
