Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are pregnant individuals aged 18-50 with type 2 diabetes requiring insulin or oral medications, diagnosed before pregnancy or early in gestation.
✕Probably not a fit
Patients with multiple gestations, major fetal anomalies, or those unable to wear CGM due to skin conditions may not benefit from this study.

What this trial studies
This clinical trial aims to determine if continuous glucose monitoring (CGM) is more effective than self-monitoring of blood glucose (SMBG) for managing type 2 diabetes in pregnant individuals. Participants will be randomly assigned to either CGM or SMBG and will monitor their blood sugar levels throughout their pregnancy. The study will also assess various risk factors that may contribute to complications for both mothers and infants. Blood samples will be collected at multiple points to evaluate glycemic control and other health indicators.
Why it matters
Potential benefit: If successful, this study could lead to improved maternal and infant health outcomes during pregnancies complicated by type 2 diabetes.
How similar studies have gone: Other studies have shown promise in using continuous glucose monitoring for diabetes management, suggesting potential success for this approach.
