Every pregnant woman with at least one risk factor, such as a family history of diabetes or a BMI of 30 or more, should be screened for gestational diabetes.

A failure to detect and treat gestational diabetes can increase the risk of birth complications for both the mother and baby, including the risk of stillbirth.

However, a recent study suggests that screening at 28 weeks, which is when the majority of tests currently take place, is happening too late, after the foetus has already been affected. It is recommended that screening is brought forward to 24 weeks which would allow the mother to implement lifestyle changes sooner and have a positive impact upon their health.

We still see cases where there was a failure to recognise the need to screen the mother for gestational diabetes at all. This study suggests that there is also more that could be done to improve the screening process after the initial decision to screen has been made.
