What is thyroid pregnancy?

If some patients suffer from thyroid diseases, they need to pay attention to take appropriate measures for treatment in time to avoid dangerous situations caused by thyroid diseases, which will seriously threaten the safety of patients, especially infertility. So what is thyroid pregnancy? Let me introduce this issue to you below.

During pregnancy, the most important result of a woman's thyroid function is FT4 - free thyroxine, because only FT4 can pass through the placenta to supply the thyroxine needed for fetal growth and development. Although the fetus will develop thyroid function at around 11 weeks, it cannot secrete thyroid hormone on its own, so it depends on the mother to provide thyroid hormone throughout the pregnancy. Now the results are very obvious. There is simply not enough thyroid hormone (FT4 has decreased), both for the mother and the fetus. Therefore, you need to take a medicine first. This medicine is called levothyroxine tablets, which is a kind of artificially made thyroid hormone.

Thyroid adenoma requires thyroid function testing and thyroid B-ultrasound to determine whether the adenoma has affected thyroid function and the size of the thyroid adenoma. If the adenoma is large, it can be surgically removed before pregnancy and thyroid function can be followed up. If the adenoma is small, thyroid function can be followed up for a long time to prevent miscarriage during pregnancy and cause serious consequences.

If pregnant women must take antithyroid drugs during pregnancy, this will suppress the thyroid function of the fetus, thus causing congenital hypothyroidism (hypothyroidism) in the fetus, leading to cretinism after birth. If radioactive iodine is used to treat hyperthyroidism during pregnancy, the fetus will be exposed to too much radiation, resulting in serious consequences, and the pregnancy should be terminated. Patients with severe or long-term hyperthyroidism should not get pregnant. Once pregnant, artificial abortion should be performed. If patients with hyperthyroidism become pregnant, they should be classified as high-risk pregnancies, and should spend the entire pregnancy period under the joint supervision of obstetrics and endocrinology. Whether hyperthyroidism or hypothyroidism, mild cases will not affect pregnancy, but the miscarriage or stillbirth rate is higher. Male patients with severe cases may experience decreased libido, impotence, decreased sperm count and infertility. Female patients with hypothyroidism often have excessive and frequent menstruation. If not treated, it can also lead to infertility.

The above is my opinion on this issue. If the patient has a thyroid disease, the patient needs to pay attention to timely examination and treatment to avoid dangerous situations caused by the above-mentioned thyroid problems, especially pay attention to avoid infertility.
