Hyperthyroidism during pregnancy

Hyperthyroidism (hyperthyroidism) is a common endocrine disease caused by excessive secretion of thyroid hormones. Women with hyperthyroidism often show menstrual disorders, reduced or amenorrhea, and low fertility. But after treatment or untreated women with hyperthyroidism, there are many pregnant women, and the incidence is about 1: 1000 to 2500 pregnancies. Most hyperthyroidism during pregnancy is Graves' disease, which is caused mainly by autoimmune and mental stimuli and is characterized by diffuse goiter and exophthalmos. The cause of hyperthyroidism during pregnancy is basically the same as that of non-pregnancy, with Graves disease being the most common. Followed by toxic nodular goiter, thyroid autonomic high-function adenoma and so on. In addition, hyperthyroidism can occur in hyperemesis gravidarum, hydatidiform mole, malignant hydatidiform mole, and chorionic epithelial cancer.
