Continuous Glucose Monitoring In Diabetic Pregnant Women Lowers Risk Of Complications

Continuous glucose monitoring as part of antenatal care for women with diabetes improves maternal blood glucose control and lowers birth weight and risk of macrosomia* (excessive birth weight in babies), according to a study.

During pregnancy it is important that women with diabetes keep their blood glucose under control.

If not, there may be an increase in the amount of glucose reaching the baby, which makes the baby grow faster than normal, and may cause difficulties at birth as well as an increased longer term risk of insulin resistance, obesity and type 2 diabetes.

Evidence suggests that measuring glucose more often improves outcomes, but the optimum frequency of blood glucose testing is not known.

Dr Helen Murphy and colleagues examined whether continuous glucose monitoring during pregnancy can improve maternal glucose control and reduce birth weight and risk of macrosomia in babies of mothers with diabetes.

They recruited 71 pregnant women with type 1 and type 2 diabetes from antenatal clinics in the UK.

The women were randomly assigned to standard antenatal care (intermittent self monitoring of glucose levels using the finger prick technique) or intermittent monitoring plus continuous glucose monitoring (using glucose values from subcutaneous tissues measured electronically every 10 seconds, giving up to 288 measurements a day).
