[Gestational diabetes mellitus].

While the prevalence of gestational diabetes mellitus (GDM) was estimated between 5 and 10% in 2010, the application of new thresholds recommended by IADPSG and adopted in 2010 by CNGOF seems to significantly increase the number of patients affected by this pathology. A prospective single-center French study estimated in 2014 the prevalence of gestational diabetes at 14% with these criteria, making it one of the most frequent complications during pregnancy. However, to date, there is no published study using these criteria to show a benefit to the health of women and children. If a diagnosis of GDM or type 2 diabetes during pregnancy is definitively an important risk factor for maternal as well as newborn and child complications, it is probably not the case for moderate hyperglycemia discovered during pregnancy.
