Thyroiditis is an inflammation of the thyroid gland caused by an autoimmune disorder or a viral infection. In its first phase, this inflammation leads to the release of thyroid hormone from within the gland, causing hyperthyroidism and, subsequently, to a decrease in thyroid function, leading to hypothyroidism. This can be permanent (chronic thyroiditis) or temporary (subacute thyroiditis, postpartum thyroiditis).  It can also be classified according to whether it is associated with pain or not, the presence of goitre, or altered thyroid function. 

Subacute postviral thyroiditis is the most common cause of pain in the thyroid area, followed by subacute postpartum thyroiditis.  Hashimoto's thyroiditis is chronic and is the most common cause of hypothyroidism in our society. 

Thyroiditis is more common in women, but its prevalence and the age of onset vary depending on the cause.  

Thyroiditis explained in first person

Professionals and patients explain how you live with the disease
Thyroiditis is a process that, in the vast majority, is transitory due to a virus or after giving birth. In those cases of chronic thyroiditis, a treatment with thyroid hormones will be needed, which will not change the quality of life or the prognosis or longevity of the patient.
