Perinatal outcomes in type 2 diabetes

Over the past decade the prevalence of type 2 diabetes in pregnancy has continued to increase. It is vital that health care professionals recognize that preconception care is just as important for mothers with type 2 diabetes as it is in type 1 diabetes. All women with type 2 diabetes should be advised regarding safe effective contraception and the benefits of optimal glycemic control, folic acid supplementation, and avoidance of potentially harmful mediations before attempting pregnancy. Glycemic control is the most important modifiable risk factor for congenital anomaly in women with type 2 diabetes, whereas maternal obesity and social disadvantage are associated with large for gestational age neonates. This review aims to bring the reader up to date with the burden of perinatal outcomes and clinical interventions to improve maternal and infant health. It warns that the consequences of type 2 diabetes pregnancy do not end at birth

Role of continuous glucose monitoring in the management of diabetic pregnancy

Self-monitoring of blood glucose (SMBG) with intermittent capillary glucose fingerstick tests is currently the universally accepted method of glucose monitoring in pregnancy. During pregnancy SMBG tests are recommended before and after meals and before bed (typically 7 values/d). Continuous glucose monitoring systems consist of a disposable subcutaneous glucose-sensing device, electrochemically measuring glucose levels in subcutaneous tissues every 10 seconds, providing an average interstitial glucose value every 5 minutes (typically 288 values/d). From a research perspective this provides unprecedented insights into the pathophysiology of glucose metabolism, while from a clinical perspective it can facilitate enhanced patient-professional decision making, patient motivation, and improved glycaemic control. CGM has thus been described as a "roadmap for effective self-management" and as a "stepping stone in the journey towards a cure." This review will consider the lessons learned and evidence supporting current and potential future use of CGM in the management of diabetes in pregnancy
