diabetes in pregnancyA recent study in the journal Diabetes Care reports no positive benefit from continuous monitoring of pregestational diabetes in pregnant women. Women recruited for the study were diagnosed with either type 1 or type 2 diabetes prior to pregnancy. All women continued self-care in addition to the intermittent continuous glucose monitoring (CGM) protocol tested for the study.

Researchers recruited 154 women with pregestational diabetes. The type 1 diabetes group consisted of 123 women with the remaining 31 placed in the type 2 group. CGM was used to track glucose levels for six day stretches 8 weeks, 12 weeks, 21 weeks, 27 weeks and 33 weeks gestation. Results of CGM were tracked by the primary care physician.

Conclusion: CGM did not positively impact pregnancy outcome when used intermittently by women with pregestational diabetes. Real-time monitoring for pregnant women with type 1 or type 2 diabetes did not necessarily change overall disease control or reduce the risk of pregnancy complications associated with diabetes, including large for gestational age births or severe hypoglycemia.
