Hypothyroidism during pregnancy, no medication, healthy child

If I don't take medicine for hypothyroidism during pregnancy, will my baby be healthy? Generally speaking, women with hypothyroidism can have children. Although hypothyroidism is hereditary, it is not 100% certain to be passed on to children. Therefore, it is possible to conceive with hypothyroidism. Let’s take a look at it in action below!

1. Can you get pregnant with hypothyroidism?

Can you get pregnant with hypothyroidism?

Thyroid disease is a multi-genetic disease. Generally, nearly half of the children and siblings of people with hypothyroidism will be tested positive for thyroid cyst-related antigens, and these antigens may cause them to develop thyroid disease in the future.

Although hypothyroidism is related to genetic inheritance, the disease is also caused by the interaction of environmental factors. Therefore, even if parents have hypothyroidism, the child will not necessarily suffer from hypothyroidism. In addition, there is a certain possibility that the hypothyroidism gene will not be easily passed on to children.

Does hypothyroidism affect pregnancy? Generally speaking, hypothyroidism is not likely to affect pregnancy. However, if the hypothyroidism is very severe, the body's structural tissues including the uterus and ovaries are in a state of myxedema, which will have a certain impact on pregnancy.

1. The pregnancy rate of pregnant women with hypothyroidism is reduced, but after treatment, pregnancy will be no problem.

2. If a normal woman is preparing for pregnancy, she should have her thyroid function checked at least 3 months before pregnancy. When women with hypothyroidism are preparing for pregnancy, they should strictly control their thyroid function, and the control index value should be TSH at 0.3-2.5mIU/L.

3. The dosage of thyroid hormone during pregnancy generally increases by 30%-50%, so thyroid function tests should be reviewed every 4-6 weeks to adjust the dosage of thyroid hormone. The normal range of thyroid hormone index values ​​during pregnancy fluctuates. At present, it is generally believed that the blood cell TSH should be maintained at 0.3-2.5mIU/L throughout the pregnancy. It is best for FT4 to be in the upper 1/3 of the normal range. However, since the standard value range of FT4 is reduced from the middle to late pregnancy, there is currently no recognized standard value range for blood cell thyroid hormones in different stages of pregnancy. Therefore, when evaluating the thyroid hormone of pregnant women, TSH should be the main factor, and FT4 should be used as an auxiliary factor for assessment and evaluation.

4. After giving birth, pregnant women should immediately reduce the amount of thyroid hormone used by 30%-50%. They should have their thyroid function checked again one month after giving birth and adjust the dosage of thyroid hormone after giving birth. If a pregnant woman's TPOAb and/or TgAb are positive, she should have regular follow-up thyroid function tests within 1 year after giving birth, because the incidence of onychomycosis in such pregnant women increases significantly after giving birth.

5. For newborns, as long as the pregnant woman's thyroid function is well regulated during pregnancy, there should be no problems, including physical and mental; and now almost all hospitals will screen for congenital hypothyroidism after the newborn is born, so there is no need to worry.

What should be paid attention to during pregnancy with hypothyroidism? If the mother has undergone thyroid surgery or has had thyroid disease before, then the thyroid hormone must be checked at the beginning of pregnancy, because the demand for thyroid hormone is different during pregnancy. If the thyroid hormone secretion is insufficient, a large amount of thyroid hormone must be supplemented in time.

Because the patient's thyroid hormone secretion is insufficient, if pregnant, it may affect the fetal neurological and brain development, increase the risk of premature birth, miscarriage, low birth weight, stillbirth and gestational hypertension. Therefore, if patients with hypothyroidism want to get pregnant, they should actively seek treatment and reduce their blood thyroid-stimulating hormone (TSH) to below 2.5 micrograms/liter to become pregnant.

During pregnancy, patients with hypothyroidism should choose levothyroxine (L-T4) treatment under the guidance of a professional doctor, and the dosage should increase with the extension of the pregnancy week. It is best to take the medication on an empty stomach in the morning. If vomiting is severe in the early stages of pregnancy, you can delay taking it. Thyroxine levels should be monitored regularly throughout pregnancy. You still need to take medicine after giving birth, and the dosage should be reduced to the level before pregnancy, and the TSH level should be reviewed 6 weeks after giving birth.

Pregnant mothers with hypothyroidism should also pay attention to: increase nutrition during the medication period, supplement iodine appropriately, pay attention to rest, and avoid overwork; have regular prenatal checkups, pay attention to weight, fetal abdominal circumference, and uterine height growth, and check fetal growth. Once growth retardation is found, it should be resolved as soon as possible; collect umbilical cord blood during delivery to test thyroxine and TSH. Mothers with Hashimoto's disease should also check for anti-thyroid antibodies.
