Postpartum thyroiditis

Like Hashimoto's thyroiditis, postpartum thyroiditis seems to be caused by a problem with the immune system. In the United States, postpartum thyroiditis occurs in about 5 to 10 percent of women. The first phase starts 1 to 4 months after giving birth. In this phase, you may get symptoms of hyperthyroidism because the damaged thyroid is leaking thyroid hormones out into the bloodstream. The second phase starts about 4 to 8 months after delivery. In this phase, you may get symptoms of hypothyroidism because, by this time, the thyroid has lost most of its hormones. Not everyone with postpartum thyroiditis goes through both phases. In most women who have postpartum thyroiditis, thyroid function returns to normal within 12 to 18 months after symptoms start.

Risk factors for postpartum thyroiditis include having:

Silent or painless thyroiditis

Symptoms are the same as in postpartum thyroiditis, but they are not related to having given birth.

Subacute thyroiditis

Symptoms are the same as in postpartum and silent thyroiditis, but the inflammation in the thyroid leads to pain in the neck, jaw, or ear. Unlike the other types of thyroiditis, subacute thyroiditis may be caused by an infection.
