Intensive insulin therapy in pregnancy: strategies for successful implementation in pregestational diabetes mellitus.

The role of intensive insulin therapy (IIT) in the reduction of long-term diabetes-related complications is well established. Normal blood glucose level prior to and during pregnancy is critical in reducing both short- and long-term morbidity and mortality in mother and infant. IIT in pregnancy, though occasionally challenging, is necessary to achieve and maintain normal blood glucose level during pregnancy. Current knowledge and recent advances in insulin formulations and delivery systems have improved our ability to achieve glycemic targets in pregnancy while limiting maternal and fetal morbidity. The objective of this review is to discuss contemporary strategies for successful use of IIT in pregnancy.
