What causes thyroiditis?

ANSWER

Many things can make your thyroid swell. You may have gotten an infection from a virus or bacteria. You may be taking a drug like lithium or interferon. Or you may have problems with your immune system.

One form of thyroiditis shows up after childbirth. Pregnancy has a major impact on the thyroid in general.
