Hyperthyroidism can get pregnant, some patients’ condition is well controlled and has no effect on the fetus, while some patients’ condition is not well controlled and has adverse effect on the fetus. The high level of thyroid hormone in hyperthyroid patients can lead to endocrine disorders and menstrual disorders. After timely intervention and treatment, the patient’s condition is stabilized and the ovaries can resume their normal ovulation function, and the patient can get pregnant at this time. During pregnancy, if the condition of hyperthyroidism patients is well controlled, the level of thyroid hormones in the body is stable, and the condition is stable, the fetus can grow and develop normally, and such patients have no effect on the fetus; some hyperthyroidism patients have poor control of their condition during pregnancy, which can lead to fetal growth and development limitation, fetal deformities, miscarriage, preterm labor and other adverse consequences. Therefore, when hyperthyroidism patients get pregnant, they should carry out standardized treatment under the guidance of professional physicians in a timely manner, so as to avoid delaying the condition and leading to adverse pregnancy outcomes.
