Can congenital hypothyroidism lead to pregnancy

Patients with congenital hypothyroidism can become pregnant when their condition is under stable control. Congenital hypothyroidism may be caused by thyroid hypoplasia, thyroid hormone synthesis disorders, thyroid stimulating hormone deficiency, iodine deficiency, genetic factors, and other reasons.

Patients with congenital hypothyroidism need to adjust their thyroid function to a normal range before preparing for pregnancy, and become pregnant after stable thyroid hormone levels. During pregnancy, it is necessary to regularly monitor thyroid function, adjust medication dosage based on examination results, and ensure that thyroid hormone levels are within the normal range. Thyroid hormones are crucial for the development of the fetal nervous system, and abnormal thyroid function during pregnancy may affect fetal intellectual development.

Some patients with congenital hypothyroidism have a more severe condition and their thyroid function is difficult to control and stabilize, which increases the risk of pregnancy. Low levels of thyroid hormones may lead to adverse pregnancy outcomes such as miscarriage, premature birth, and low birth weight. Severe hypothyroidism may also affect the heart function of pregnant women and increase the risk of complications during pregnancy. Patients with congenital hypothyroidism should consult an endocrinology department for a comprehensive thyroid function assessment before planning pregnancy. During pregnancy, it is necessary to strengthen prenatal check ups, closely monitor changes in thyroid function, and adjust medication doses according to medical advice. Daily attention should be paid to ensuring sufficient iodine intake, avoiding excessive fatigue, and maintaining a regular schedule, which can help maintain stable thyroid function. Postpartum monitoring of thyroid function is still necessary, and some patients may require lifelong use of thyroid hormone replacement therapy.
