Once the expectant mother is diagnosed with the disease, she can choose to get pregnant after effective treatment before pregnancy. According to experts It said that expectant mothers with clinical hypothyroidism should have their thyroid function tested every 4 weeks during the first half of pregnancy (1 to 20 weeks). Because before 20 weeks of pregnancy is the first period of rapid brain development of the fetus, and The fetal thyroid gland does not begin to secrete thyroid hormone until the 12th week of pregnancy, and the thyroid function cannot be fully established until the 20th week of pregnancy.

According to the test results, it can be divided into hyperthyroidism, hypothyroidism or subhyperthyroidism and hypothyroidism. If TSH is reduced and FT3 and FT4 are elevated, it indicates hyperthyroidism. TSH increases while FT3 and FT4 decreaseLow is hypothyroidism. Iodine supplementation during pregnancy is indispensable. Iodine is an essential mineral for the body to produce thyroid hormones. After the second trimester, the fetus\’s own production of thyroid hormone also requires the mother-to-be to take in a sufficient amount of iodine.
