Thyroid-stimulating hormone 6.5 μIU/ml pregnant child can be considered, but there are risks. The normal range of thyroid stimulating hormone is 0.35 to 5.5 μIU/ml, and its increase needs to be considered as a possibility of primary hypothyroidism. The state of hypothyroidism in pregnancy may lead to preterm delivery, miscarriage, and may also affect the intellectual and neurological development of the fetus, so the endocrinologist should be consulted as early as possible for treatment of hypothyroidism to minimize the impact on the fetus as much as possible. In the early stage of pregnancy, i.e. the first trimester, thyrotropin should be controlled below 2.5 μIU/ml in order to better ensure the development of the fetal nervous system and growth and development. Therefore, pregnant women with a thyrotropin level of 6.5 μIU/ml are advised to seek prompt medical attention for targeted treatment under the guidance of a doctor.
