There is no debate that all pregnant women should be screened for Gestational Diabetes Mellitus (GDM) between 24 and 28 weeks. However, there are two different approaches to screening for GDM. ACOG currently prefers the traditional ‘two-step’ approach, using an initial screen that, if positive, requires an additional confirmatory test. Alternatively, there is the option of the International Association of Diabetes and Pregnancy Study Groups that recommend a ‘one-step’ approach as follows
Unfortunately, with the obesity epidemic and more sedentary lifestyles, GDM is increasing as well, and being observed in younger age groups. Complications are significant, including birth trauma to both mother and child. Treatment including diet, increased exercise and if necessary medications can be effective, if GDM is identified in time to implement these changes to achieve best results.
