This guideline provides an update to the 1999 WHO recommendations for diagnosing and classifying hyperglycaemia in pregnancy. The target users are health care professionals who care for pregnant women, most frequently primary care physicians and obstetricians/gynaecologists. However, researchers and policy makers will also find it useful.
