Does hyperthyroidism have a big impact on the fetus during pregnancy?

Pregnancy is a special stage for a woman, and with a baby in her arms, of course she needs to take him into consideration at all times. According to research findings, pregnancy is a high-risk period for hyperthyroidism, and hyperthyroidism has a certain impact on the fetus. The effective way is to see a doctor immediately for appropriate examinations. Next, let’s take a closer look at the impact of hyperthyroidism during pregnancy on the fetus.

Hyperthyroidism favors marriage and childbearing. Originally, women with hyperthyroidism could not get pregnant, but they did get pregnant unintentionally. New onset of hyperthyroidism during pregnancy is also common, with an incidence of 0.5% to 2%. Pregnant women with hyperthyroidism may suffer from miscarriage, premature birth and fetal growth retardation; the incidence of pregnancy-induced hypertension syndrome increases with hyperthyroidism; pregnant women with hyperthyroidism are prone to uterine atony during labor, which increases the rate of dystocia. The perinatal mortality rate of pregnant women with hyperthyroidism is increased. Because the high-efficiency thyroid-stimulating hormone in the pregnant mother enters the fetus through the embryo and causes congenital hyperthyroidism. Continuous medication for hyperthyroidism will inhibit fetal thyroid hormone, resulting in congenital hypothyroidism, affecting the growth and development of the fetal central nervous system and causing delayed fetal brain development.

The use of iodine in the diagnosis and treatment of hyperthyroidism patients can cause acute thyroid nodules in the fetus, which can compress the bronchus and cause suffocation. In severe cases, it can even lead to stillbirth. Malformed fetuses are common when pregnant women suffer from hyperthyroidism. Hyperthyroidism increases the incidence of low birth weight and premature babies, and the mortality rate of newborns and perinatal infants. Pregnant women with hyperthyroidism are prone to miscarriage, fetal malformation, and fetal death in the uterine cavity when taking large amounts of anti-thyroid drugs during pregnancy.

The above is a detailed introduction to the impact of hyperthyroidism during pregnancy on the fetus. In short, hyperthyroidism means that the thyroid hormone is relatively hyperactive. This type of disease is more common in clinical medicine, and is more common in female patients. In more serious cases, hyperthyroidism crisis, coma and even serious threat to life may occur.
