Can pregnancy trigger goiter?

Yes: All pregnant women develop a subtle goiter during pregnancy. Some women may develop thyroid problems in pregnancy. These are checked with a simple blood test.

Hashimotos : Most cases of goiter are autoimmune in nature. This means your own body is sending antibodies to inflame the gland. Pregnancy is one of the peak times of physiologic stress where this happens. The others are adolescence and menopause. Your doctor can measure antibodies and thyroid function.
