 Gestational diabetes GDM is a condition of carbohydrate intolerance with onset or first recognition in pregnancy. The prevalence of GDM is as high as 25 in some populations and continues to rise with the increase in obesity and type-2 diabetes. GDM places the pregnancy at great risk to both the mother and the neonate. Recent studies have proven that interventions including dietary and medications lower the risk to the pregnancy. Both the American College of Obstetrics and Gynecology ACOG and the American Diabetes Association ADA recommend dietary interventions with daily glucose monitoring as the initial treatment of choice. Meanwhile, outside of pregnancy, promising new technologies such as continuous glucose monitors CGM are revolutionizing diabetic care. The investigators seek to determine if the constant feedback of a real-time CGM system would improve glycemic control compared to traditional management in GDM
