Women with gestational diabetes mellitus require a continuum of care before, during, and after pregnancy for optimal management of hyperglycemia. Postpartum education and lifestyle modification should begin during pregnancy, and should continue during the postpartum period. Women should receive education on the long-term risk of type 2 diabetes mellitus, and should be encouraged to breastfeed, engage in regular physical activity, and select a highly effective contraceptive method in preparation for subsequent pregnancy. Postpartum women with gestational diabetes mellitus should be empowered to take ownership of their own health, including knowledge of health indicators such as weight, waist circumference hemoglobin A1C levels, and fasting and postprandial blood glucose levels.
