There are significant changes that occur in the thyroid gland and its function during pregnancy, thus making the assessment of thyroid functions in pregnancy substantially important. Normal pregnancy is associated with an increase in renal iodine excretion, an increase in T4 binding proteins, an increase in thyroid hormone production, and thyroid stimulatory effects of human chorionic gonadotropin (hCG), and the treatment targets are different from women who are not pregnant. Both hypothyroidism and hyperthyroidism are associated with significant impact on the fetomaternal unit and pregnancy outcomes. Evidence appears to support an association between overt thyroid dysfunction and an increased risk of infertility, and there is strong evidence to recommend treatment for overt hypothyroidism in pregnancy. The recommended treatment of maternal hypothyroidism is the administration of oral LT4.
