Using continuous glucose monitors during pregnancy for women with type 2 diabetes
Official title: Continuous Glucose Monitor Use and Perinatal Outcomes Among Pregnant Women With Type 2 Diabetes Mellitus: A Randomized Controlled Trial
Run by University of Massachusetts, Worcester · NCT05317585 · Data updated 2026-11-12
This study is testing if using continuous glucose monitors during pregnancy can help women with type 2 diabetes manage their blood sugar better and have healthier babies compared to the usual fingerstick method.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are pregnant women aged 18 and older with a diagnosis of type 2 diabetes and a singleton gestation of 14 weeks or less.
✕Probably not a fit
Patients with type 1 diabetes, gestational diabetes, multifetal gestation, or those planning to receive care outside of the study location may not benefit from this study.

What this trial studies
This study aims to compare the effectiveness of continuous glucose monitoring (CGM) versus standard fingerstick glucose monitoring in 180 pregnant women with type 2 diabetes mellitus (T2DM). The randomized controlled trial will assess the impact of CGM on maternal glycemic control, patient satisfaction, and adverse perinatal outcomes, particularly focusing on the incidence of large for gestational age infants. The study addresses a gap in research regarding CGM use in this population, which has been minimally studied despite its potential benefits. By providing detailed insights into glucose fluctuations, CGM may improve outcomes for both mothers and infants.
Why it matters
Potential benefit: If successful, this study could lead to improved glycemic control and reduced adverse outcomes for pregnant women with type 2 diabetes.
How similar studies have gone: Preliminary studies have shown improvement in outcomes for pregnant women with type 1 diabetes using CGM, suggesting potential success for this approach in women with type 2 diabetes.
