Thyroid disease is common in pregnancy and complicates up to 2-3% of all pregnancies. Euthyroid autoimmune disease has been reported in 10% of pregnant women. Better understanding the physiology of and the importance of the thyroid function in pregnancy within the last twenty years has helped to elucidate the relationship between untreated thyroid diseases with negative consequences of maternal and neonatal results. Raising awareness of thyroid disease is required to reduce the rate of complications in pregnancy. In this review neonatal outcomes and the etiology of thyroid disease in pregnancy will be discussed.

Tiroid hastalıkları gebelikte sık görülür. Tüm gebeliklerin en az %2-3’ü tiroid fonksiyon bozukluklarından etkilenir ve %10 kadarı ise ötiroid olmasına rağmen otoimmun tiroid hastalığına sahiptir. Son yirmi yıl içinde gebelikte tiroid fizyolojisinin daha iyi anlaşılması, gebeliğe tiroid fonksiyonlarının adaptasyonunun önemini ve tedavi edilmeyen tiroid hastalıklarının hipo ya da hipertiroidi maternal ve neonatal olumsuz sonuçlarla ilişkisinin ortaya koyulmasını sağlamıştır. Komplikasyon oranının azaltılması için gebelikte tiroid hastalıklarına farkındalığın artırılması gerekmektedir. Bu derlemede gebelikte görülen tiroid hastalıklarının etyolojileri ve neonatal sonuçları üzerinde durulacaktır.
