During pregnancy physiologic changes in thyroid function occur which should not be misinterpreted as pathological. Thyroid disorders may complicate pregnancy and need thorough investigation and treatment in order to ensure a favourable pregnancy outcome. The incidence of hyperthyroidism in pregnant women has been reported to be approximately 0.2%. The leading cause is Graves' disease. Treatment of hyperthyroidism includes antithyroid drugs or surgery to avoid adverse effects on the neonate such as prematurity, intrauterine growth retardation and fetal or neonatal thyrotoxicosis. Use of radioactive iodine is contraindicated. Hypothyroidism during pregnancy is associated with gestational hypertension and low birth weight. Women on thyroid replacement therapy before pregnancy may require an increase in dosage during pregnancy. Pregnant women with chronic autoimmune thyroiditis have a higher incidence of spontaneous miscarriage. Nodular disease demands meticulous investigation to rule out a toxic adenoma or malignancy.

Within one year following delivery, about 5-10% of women may exhibit postpartum autoimmune thyroid dysfunction, which may result in hypothyroidism.
