Thyroid hormones necassary for fertility, pregnancy and fetal devalopment. Maternal thyrotropin can’t across plascenta, free thyroxine and treeiodothyronine across placenta. All fetus before 12th weeks of pregnancy and fetus with congenital hypothyroidia need maternal thyroid hormones during pregnancy. Thyroid hormones are crucial for central nervus system development. TSH is the most vulnerable test for determining thyroid function. Pregnant women with thyroid disease or are at risk of thyroid disease should undergo thyroid function test. All pregnant should be evaluated for thyroid function test is uncertain. There are different suggestions about this subject. Until this subject has certain end pregnant women should be screened for thyroid function test

Anahtar Kelimeler

Gebelik ve Tiroid Hormonları

Öz

Tiroid hormonları gebelik oluşumu, devamı ve fetal gelişim için gereklidir. Maternal tirotropin plasentadan geçmez. Serbest tiroksin ve serbest trioiodotironin plasentadan geçer. Tüm fetüsler 12’inci gebelik haftasından önce ve konjenital hipotiroidisi olan fetüsler gebelik süresince maternal tiroid hormonuna gereksinim duyarlar. Tiroid hormone santral sinir sisteminin gelişmesinde önemlidir. Tiroid fonksiyon testleri içinde en hassas olanı TSH’dır. Önceden bilinen tiroid hastalığı olan veya riskli grupta bulunanlara gebelikte tiroid değerlendir-mesi yapılması önerilmektedir. Tüm gebelere tiroid değerlendirmesi yapılıp yapılmayacağı tartışılmaktadır. Bu konuda farklı komite ve konsensus kararları vardır. Bu konu kesin netlik kazanana kadar tüm gebelere tiroid fonksiyonu taraması yapılmasının yararlı olacağına inanıyorum
