Nine of them (%69.2) were diagnosed in the first trimester and 4 of them (%30.8) were diagnosed in the second trimester.Discussion: The incidence of type 2 diabetes mellitus has been increasing in the world. An anormous amount of subtle diabetic patiens are diagnosed during pregnancy with GDM screening. We have found that screening before 14 weeks of pregnancy could detect %69.2 of GDM patients. To the best of our knowledge, this is the first study that investigate the early GDM screening in the Turkish pregnant population.
