Continuous glucose monitoring lowers pregnancy complications risk
Continuous glucose monitoring in pregnant women lowers the risk of complications for both the mother and her unborn child, new research has found.
Previous evidence has suggested pregnant women with diabetes who measure their blood glucose more often have improved outcomes compared with those who monitor blood glucose less frequently.
But the optimum frequency at which women should test their blood glucose level is not known.
The new study, published online by the BMJ, looked at 71 women with type 1 and type 2 diabetes randomised to either standard antenatal care and intermittent blood glucose testing, or continuous glucose monitoring.
It found women in the continuous glucose monitoring group had a mean HbA1c of just 5.8% from 32 to 36 weeks' gestation, compared with 6.4% in women receiving standard antenatal care.
Babies of mothers who had continuous monitoring also had lower birth weight and reduced risk of excessive birth weight, or macrosomia.
But macrosomia rates were still 3.5 times higher in women using continuous glucose monitoring than in the general population of mothers, and the researchers stressed the need for closer monitoring in women with diabetes.
Dr Helen Murphy, senior research fellow at the Ipswich hospital where the study was conducted, concluded: ‘These results show that continuous glucose monitoring during routine antenatal care can provide added benefits to the pregnancy outcomes for women with diabetes and their infants.'
