Abstract (EN): Background: Bariatric surgery has been shown to improve many obesity related co-morbidities, including gestational diabetes mellitus (GDM). Recently, new diagnostic criteria for GDM following the International Association of Diabetes and Pregnancy Study Group recommendations were implemented. The objective of this study was to compare the use of 2 different GDM criteria in diagnostic and pregnancy outcome after Roux-en-Y gastric bypass (RYGB). Methods: Pregnant women who had previously undergone RYGB (n = 30) were screened for GDM with Carpenter and Coustan (C&C) criteria (n = 18) or the new diagnostic criteria (n = 12). Results: None of the patients screened using C&C criteria where diagnosed with GDM, while 50% of the patients screened with the new criteria had GDM. Among women that underwent oral glucose tolerance tests (OGTT) (n = 19) as required for the new diagnostic criteria, 57.9% developed reactive hypoglycemia. All women diagnosed with GDM had excellent metabolic control during pregnancy and comparing the outcome of these pregnancies and those of women without GDM, there were no significant differences regarding the age at time of surgery or at pregnancy, body mass index before surgery and pregnancy, parity, previous history of GDM, time from surgery to conception, weight lost until pregnancy, weight gain during pregnancy, gestational age at delivery, and birth weight adjusted for gestational age. Conclusion: New GDM diagnostic criteria in post-RYGB pregnant women increased the prevalence of GDM diagnostic without changing pregnancy outcomes. In addition, OGTTs were associated with a high rate of reactive hypoglycemia. These data suggest that alternative GDM diagnostic criteria are needed for these postbariatric patients.
