Dr. Pan Yongyuan
Pregnant women may develop hyperthyroidism due to elevated levels of sex hormones in the body. After conception, human chorionic gonadotropin (hCG) often increases abnormally, which may stimulate the thyroid gland to produce more thyroid hormones. Hyperthyroidism in pregnant women may also be caused by genetic factors; if a parent has hyperthyroidism, the likelihood of their children developing the condition increases.
