Abstract (2. Language): 
The diagnosis and the early treatment of the thyroid diseases occuring before and during pregnancy are essential for both mother and baby. Increased synthesis of the thyroid hormones, urinary iodine loss, and transfer of iodine to the fetus through the placenta increase the daily iodine requirement in pregnant women. In order to evaluate the thyroid functions in pregnant women, the serum free T4 (fT4), free T3 (fT3), and TSH levels should be determined. Low levels of maternal and fetal thyroxin, lead to irreversible central nervous system development defects, where endemic cretinism and mental retardation are the most significant complications. Therefore, if possible, iodine treatment should be initiated prior to pregnancy. On the other hand hyperthyroidism, can lead to complications such as abortion, premature birth, preeclampsia, and placenta detachment. Thus, thyroid function tests should be monitored carefully during pregnancy
Abstract (Original Language): 
Gebelik öncesi ve gebelik sırasında görülen tiroid hastalıklarının tanınması ve erken tedavi edilmesi, hem anne hem de bebek için çok önemlidir. Tiroid hormon sentezinin artması, idrar ile iyot kaybı ve plasenta yolu ile fetusa iyot geçişi gebelerin günlük iyot gereksinimini arttırır. Gebelerde tiroid fonksiyonlarını değerlendirebilmek için serum serbest T4 (sT4), serbest T3 (sT3) ve TSH seviyeleri tayin edilmelidir. Maternal ve fetal tiroksin düşüklüğü geri dönüşü olmayan SSS gelişim defektlerine yol açmaktadır. Endemik kretenizm ve zekâ geriliği en önemli komplikasyonlardandır. Bu nedenle iyot tedavisine mümkünse gebelik öncesi başlanmalıdır. Hipertiroidizm durumunda ise abortus, prematüre doğum, preeklampsi ve plasenta dekolmanı gibi komplikasyonlara yol açabilir. Bu nedenle gebelik sırasında tiroid fonksiyon testleri dikkatle takip edilmelidir.
