Background and Aims: Pregnancy complicated with poorly controlled thyrotoxicosis is associated with an increased risk of adverse pregnancy outcomes, and maternal complications. To study the clinical characteristics, feto-maternal outcomes in women with Graves’ disease (GD) during pregnancy. Methods: This was observational study on 98 patients with GD during pregnancy at the tertiary care hospital. GD was documented by Thyrotropin receptor antibody (TRAb). Patients were subjected to complete clinical work up and thyroid profile. The diagnosis of TAO was based on the criteria of Bartley and Gorman. 100 pregnant women with normal thyroid function were taken as control. Birth outcomes recorded were: route of delivery (vaginal or cesarean section), neonatal birth weight, spontaneous abortion, stillbirth, and small for gestational age (SGA). Maternal outcomes accessed were: gestational hypertension, gestational diabetes (GDM), preeclampsia, gestational age at delivery, preterm delivery, antepartum hemorrhage, and postpartum hemorrhage. Results: The mean age of the patients was 30.8±7.6 years as compared to 32.9±6.8 years in controls. Compared with the controls; the pregnant women with GD had significantly higher rates of small for gestational age (SGA) (23.5% vs. 12.0%; p: 0.034), preterm birth (22.4% vs. 12.0%; p: 0.049), preeclampsia (15.3% vs. 5.0%; p: 0.016) and cesarean section (82.7% vs.70.0%; p: 0.036). Maternal and neonatal outcomes in pregnant women with GD with controlled and uncontrolled thyrotoxicosis were not significantly different except for birth weight. Conclusion: GD was significantly associated with an increased risk of adverse pregnancy outcomes.
