Effects of low thyroid hormone levels in pregnant women on the fetus

Pregnancy check-up cannot be delayed during the ten months of pregnancy. Through prenatal check-up, the development of the baby and the health status of the pregnant woman can be checked. If there is a problem with the pregnant woman's body, it will also affect the fetus. Therefore, during the pregnancy check-up, the doctor will recommend a thyroid hormone test. Low thyroid hormone will affect the fetus. How much impact will low thyroid hormone have on the fetus?

How much does low thyroid hormone affect the fetus?

1. Abnormal growth and development of the central nervous system: Thyroid hormone is an essential growth hormone for the growth and development of the fetal central nervous system. Thyroid hormone deficiency can cause growth and development disorders in the fetal central nervous system, especially in the early stages of pregnancy when the mother's thyroid hormone supply is insufficient, which can cause reversible damage to the fetal central nervous system.

2. Abnormal eye vision development: If pregnant women have insufficient thyroid hormone in the early stages of pregnancy, their offspring will have abnormalities in visual concentration, visual response ability, and basic motor skills; and if they have insufficient thyroid hormone in the late stages of pregnancy, in addition to causing decreased reaction time and fine motor disorders, it will also increase the risk of abnormalities in visual differential sensitivity and visual spatial ability.

3. In addition: Insufficient thyroid hormone during pregnancy can significantly increase the risk of fetal intrauterine growth restriction, low birth weight, congenital malformations, fetal death, stillbirth and perinatal death.

Causes of low thyroid hormone in pregnancy

If pregnant women have slightly low thyroid-stimulating hormone, it may be due to problems with thyroid hormone, or it may be related to their physical fitness or unscientific diet. Women should eat less high-iodine foods during pregnancy to ensure a balance between protein supply and demand and to ensure adequate nutrients. Growth hormone during pregnancy will reduce TSH value, which is due to the self-adjustment of the human immune system. As long as T3T4FT3FT4 are normal, there will be no impact. You should go for a follow-up visit to observe the changes.

Iodine is an essential nutrient for the body and is the basic raw material for thyroid cysts to produce thyroid hormones. A low-salt and low-calorie diet is a good choice. Eat more fresh fruits and vegetables. It is recommended to choose iodized salt.

Low thyroid hormone levels in pregnant women can cause great harm to the fetus. Therefore, if a pregnant woman is found to have low thyroid hormone levels during prenatal examination, she should be treated promptly. For pregnant women with low thyroid hormone, they should pay attention to their daily diet. They should avoid eating foods and medicines containing iodine, and eat more vitamins, proteins, and foods rich in carbohydrates.
