What is thyroiditis?
Thyroiditis (thy-roi-DY-tiss) is inflammation, or swelling, of the thyroid.
There are several types of thyroiditis, one of which is Hashimoto's thyroiditis.
What are other types and symptoms of 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.
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.
