Establishing diagnosis of gestational diabetes mellitus: Impact of the hyperglycemia and adverse pregnancy outcome study

Abstract

The diagnosis of gestational diabetes mellitus (GDM) remains controversial, without universal acceptance of a particular set of diagnostic criteria, and, in fact, a lack of consensus as to whether this is an entity worth diagnosis. Some of the debate derives from differences of opinion about what degree of glucose intolerance should be labeled as GDM. Therefore, it is to be expected that there are different viewpoints on how to detect and screen for GDM. It is believed that early diagnosis will result in a significant improvement in perinatal outcome in these patients. In this review, we discuss the current data concerning screening for GDM and new strategies for GDM diagnosis in light of the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study.
