Hyperthyroidism in pregnancy
Summary o Thyroid diseases are common in women, including at the time of pregnancies.
o Many typical features of hyperthyroidism are common in normal pregnancies and this may delay or mask the diagnosis.
o Uncontrolled thyrotoxicosis increases the rate of miscarriage, intrauterine growth restriction (IUGR), premature labour and perinatal mortality.
o Multi-disciplinary efforts are required to achieve optimal control of thyrotoxicosis.
o Anti-thyroid drugs are safe and should be used with the lowest possible doses.
o Radioiodine treatment is contraindicated during pregnancy and lactation.
o Indications of surgery include: compression symptoms, thyroid malignancy, non-compliance to medications or when the patient develop drugs side effects.
