Diabetes during pregnancy

Blood glucose targets

Aiming for blood glucose levels as close to target as possible can help reduce the risk of heath problems for you and your baby. Your diabetes in pregnancy team will discuss individual blood glucose targets with you. 

Current Australian guidelines for women with type 1 or type 2 diabetes during pregnancy recommend blood glucose levels between 4.0 - 5.5 mmol/L fasting/before meals and less than 7mmol/L two hours after meals.

However, for women with type 1 diabetes, the targets below may be suggested by your diabetes in pregnancy team to take into account the need for optimal blood glucose levels during pregnancy, while minimising the risk of hypos.

Your team may also advise you to monitor your blood glucose levels at other times.


Fasting/before meals:                                                   4.0 – 6.0 mmol/L


2 hours after each meal:                                              5.5 - 7.5 mmol/L
