Type 2 diabetes in pregnancy: a wolf in sheep's clothing.

Type 2 diabetes is now the most common form of pregestational diabetes. Recent data suggest that pregnancies complicated by type 2 diabetes are associated with unacceptably high fetal mortality and morbidity, at an incidence comparable to pregnancies complicated by type 1 diabetes. This review examines the literature on type 2 diabetes in pregnancy, including its incidence and potential complications. There is a need to highlight the dangers of type 2 diabetes in pregnancy to both patients and medical practitioners. Peri-conception care needs to improve to achieve better pregnancy outcomes.
