Thyroid Stimulating Hormone 6.0 Preconception Pregnant needs to be given medication under a doctor’s supervision. Pre-pregnancy thyrotropin (TSH) of 6.0 mIU/L suggests previous hypothyroidism, which will increase the risk of pre-eclampsia, fetal miscarriage, malformations, congenital defects, etc. It is necessary to actively give levothyroxine treatment under the guidance of a doctor, and regularly recheck the level of thyrotropin to adjust the dose of medication when appropriate, to control the TSH in the normal range. Pregnant women with a history of hypothyroidism before pregnancy should strengthen the management of pregnancy, strictly comply with the doctor’s instructions for timely delivery and recheck the TSH level, to guide the physician to appropriately adjust the dosage of medication, in order to reduce the occurrence of perinatal adverse pregnancy outcomes. Thyroid function tests should be performed after the birth of the newborn to detect neonatal hypothyroidism early and treat it aggressively. A comprehensive examination not only determines the health of the fetus, but also provides insight into the health of the pregnant woman herself. Pregnant women should pay attention to prenatal checkups during pregnancy, and actively listen to the advice of professional doctors to do a comprehensive care and health care work, which can effectively ensure the safety of delivery.
