Maintenance of maternal blood glucose concentration at or near normoglycemic levels is the goal of medical management of pregestational diabetes (ie, diabetes diagnosed before pregnancy, type 1 or type 2 diabetes mellitus) because it decreases the likelihood of adverse maternal, fetal, and newborn outcomes. Ideally, good glycemic control is achieved before conception and maintained through the postpartum period.

The medical management of pregestational diabetes mellitus during pregnancy will be discussed here. Multiple additional aspects of pregnancy complicated by diabetes are reviewed separately:

Optimizing glucose control before pregnancy (see "Pregestational diabetes: Preconception counseling, evaluation, and management", section on 'Preconception evaluation and management')

Fetal and maternal risks of pregnancy in women with pregestational diabetes (see "Pregestational diabetes: Preconception counseling, evaluation, and management", section on 'Fetal and neonatal risks' and "Pregestational diabetes: Preconception counseling, evaluation, and management", section on 'Obstetric complications' and "Pregestational diabetes: Preconception counseling, evaluation, and management", section on 'Maternal medical risks')

Obstetric management of pregnancy in women with pregestational diabetes (see "Pregestational diabetes mellitus: Obstetrical issues and management")
