Does hypothyroidism affect the fetus in the third trimester of pregnancy

Hypothyroidism is hypothyroidism. It affects the fetus in the third trimester of pregnancy.

Thyroid hormones are essential for the normal development of the fetal brain. In the third trimester, although the fetus 'own thyroid gland has begun to secrete hormones, it still needs the support of maternal thyroid hormones. Hypothyroidism may lead to abnormal development of the fetal nervous system and increase the risk of mental retardation. In addition, hypothyroidism can cause maternal metabolism to slow down, the utilization and transport of nutrients are affected, resulting in reduced nutrition for the fetus, which may lead to fetal growth restriction and low weight.

Therefore, pregnant women should seek medical attention in time when hypothyroidism is detected in the third trimester of pregnancy, and follow the doctor's recommendations for standardized treatment and close monitoring to minimize adverse effects on the fetus.
