RESUMO
The aim of this study was to determine the incidence of Post Partum Thyroiditis [PPT] at first month postpartum. Fifty pregnant subjects were included. Control group was composed of 50 women who did not give birth in the recent year. Blood samples were obtained once in the control group and twice -at the third trimester and the first month postpartum-in the pregnant group. PPT occurred at first month postpartum in 3 of 50 pregnant women. The incidence of PPT at first month postpartum was 6%. Among the pregnant group, there was a statistically significant increase in the Anti-TPO and Anti-Tg levels within the first month postpartum compared to the ones in the third trimester. Also, all patients who experienced PPT were positive for Anti-TPO and Anti-Tg. In our opinion, it will be useful to evaluate particularly the pregnants with positive thyroid auto-antibodies in early postpartum period
