Women with GDM are at increased risk of progression to type 2 diabetes and lifestyle interventions can reduce this risk by 55%. The American College of Obstetricians and Gynecologists (ACOG) and the American Diabetes Association (ADA) therefore recommend that women with GDM be counseled about diet, exercise, and weight reduction. However, several studies suggest that advice is insufficient to change maternal behavior, underscoring the need for comprehensive interventions to reduce long-term maternal disease risk.
