Grade: B

Before attempting to become pregnant, women with type 2 diabetes should strive to attain a pre-conception glycated haemoglobin (HbA1c) as close to normal as is safely possible (ideally ≤6.5%) to decrease the risk of congenital anomalies, pre-eclampsia, macrosomia and other complications

Before attempting to become pregnant, women with diabetes should discontinue medications that are potentially embryopathic, including any from the following classes:

Grade: Consensus

Between 24 and 28 weeks’ gestation, recommend testing for gestational diabetes mellitus (GDM) to all women who have not previously been tested in the current pregnancy. Recommend repeat testing to women who were tested early in pregnancy due to risk factors and who had a normal result on an initial test

Grade: A

Pregnant women with GDM should be offered dietary advice and blood glucose monitoring, and be treated with glucose-lowering therapy depending on target values for fasting and postprandial targets

Grade: C

Postprandial glucose monitoring should be carried out in pregnant women with GDM

Grade: Consensus

Postnatal education and support are important in preventing or delaying the onset of diabetes in the future, and women should be encouraged to attend postnatal testing

Grade: Consensus

Women diagnosed with GDM should have a 75 g two‐hour oral glucose tolerance test, preferably at 6–12 weeks postpartum, with classification according to World Health Organization criteria

Grade: Qualified evidence-based recommendation (QEBR)

Advise women that physical activity and healthy eating during pregnancy help reduce excessive weight gain but do not appear to directly reduce the risk of developing GDM
