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

Type 2 diabetes is now the most common form of pregestational 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.
