Is hyperthyroidism dangerous for pregnant women? This is a question that many pregnant women wonder. Hyperthyroidism during pregnancy has a significant impact on both mother and baby. In addition, there are some treatment methods that should be noted for pregnant women with hyperthyroidism.

Hyperthyroidism during pregnancy is usually caused by Graves' disease and occurs in 1 to 4 out of every 1,000 pregnancies in the United States. Graves' disease is an autoimmune disorder. When you have Graves' disease, your immune system creates antibodies that cause your thyroid gland to produce more hormones than normal.
