Introduction: Although early diagnosis and management of GDM aims to reduce adverse outcomes for the mother and newborn, the prognostic value of the number of abnormal values in the 75 g OGTT remains unclear. This study investigates whether single, double, or triple abnormal values in the 75 g OGTT are associated with maternal and neonatal outcomes in women diagnosed with GDM. Methods: This retrospective, single-center study included 120 pregnant women diagnosed with GDM according to IADPSG criteria based on a 75 g OGTT after an 8-hour fast between April 2024 and December 2025. Results: HbA1c was higher in Group 3 (mean difference vs. Group 1: 1.82 +/- 0.32, p<0.001); cesarean rates were 95% in Group 1 vs. 60% in Group 3 (absolute difference: 35%, p=0.024). Macrosomia, Apgar scores at 1 and 5 minutes, admission to the NICU, neonatal hypoglycemia, and hyperbilirubinemia, among other neonatal outcomes, did not differ significantly between groups. Conclusion: Among pregnant women diagnosed with GDM using a 75 g OGTT, increased abnormal values were associated with higher maternal HbA1c and increased likelihood of cesarean delivery, but this did not lead to consistent differences in neonatal morbidity.
