Thyroid abnormalities can have an impact on the pregnant woman and the fetus.
Clinically, thyroid abnormalities occurring in pregnant women are mainly hyperthyroidism and hypothyroidism. Hyperthyroidism is mainly caused by over-production of thyroid hormones, which may lead to miscarriage, preterm labor or hyperthyroidism crisis; it may also lead to growth and developmental disorders in the fetus or increase the risk of thyroid disease after birth.
When pregnant women suffer from hypothyroidism, due to insufficient secretion of thyroid hormones, miscarriage and preterm labor may also occur; the effects on the fetus mainly include malformations, congenital defects and mental retardation.
Therefore, timely treatment is recommended for pregnant women with thyroid abnormalities.
