What are the effects of hypothyroidism during pregnancy on the baby?

Doctors have always emphasized that if a couple wants to have a child, they must prepare for pregnancy well to ensure the health of the fetus and the safety of the pregnant woman. Some people neglected pregnancy preparation, which led to various problems in the early stages of pregnancy, such as hypothyroidism. So, what impact does hypothyroidism during pregnancy have on the child? Hypothyroidism has a certain impact on the secretion of thyroid hormones and the intelligence of the fetus, and may even cause premature birth. Therefore, it is necessary to control the level of hypothyroidism in a timely manner through scientific and effective methods.

During pregnancy, if the pregnant woman has hypothyroidism, the risk of adverse pregnancy outcomes will increase, such as premature birth or even miscarriage. It will also affect the baby's intellectual development, and the baby's nerve reaction ability and motor ability will be affected. The thyroid gland is the most important endocrine organ in the human body. The thyroid hormone secreted is involved in the body's growth and development and the metabolic regulation of various organ systems. It is also a hormone necessary for the development of fetal brain nerves.

Before 20 weeks of pregnancy is the first stage of rapid brain development of the fetus, because the fetus begins to secrete thyroid hormone at 12 weeks, and thyroid function is fully established after 20 weeks. Therefore, before 20 weeks of pregnancy, the thyroid hormone needed for growth and development is completely supplied by the mother. During this period, if the pregnant woman's own thyroid function is normal, then sufficient thyroid hormone can be delivered to the fetus through the placenta to meet the fetus's first period of rapid brain development.

However, because the mother's physiological demand for thyroid hormones increases during pregnancy, if the thyroid gland is under stress and cannot adapt well to the changes during pregnancy, pregnancy-related hypothyroidism will occur. If a woman finds that she has hypothyroidism after becoming pregnant, it will definitely have some impact on the baby. However, people don’t need to worry too much, because medical technology is now very advanced. For this situation, people only need to go to the hospital regularly for relevant examinations and supplement thyroid hormone. If you find out that you have this problem before you become pregnant, it is best to treat the disease first and then plan to become pregnant.
