Summary

This trial uses a device to track blood sugar levels in women who had diabetes during pregnancy. These women are at high risk for developing type 2 diabetes later. The study aims to understand their blood sugar patterns after childbirth and improve screening methods for diabetes.

Who is the study for?
This trial is for women who had gestational diabetes during a single pregnancy with no fetal anomalies, diagnosed before 20 weeks or at/after 24 weeks and required medication. It's not for those with skin conditions affecting glucose monitor use, history of prediabetes, PCOS, or pregestational type 2 diabetes.
What is being tested?
The study tests how well two methods can track blood sugar levels after childbirth in women at risk for long-term high blood sugar. One method is a standard oral glucose tolerance test; the other uses a Dexcom G6 Pro continuous glucose monitor.
What are the potential side effects?
Potential side effects may include discomfort from wearing the continuous glucose monitor on the skin and possible reactions to the oral glucose solution like nausea or bloating.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Postpartum GDMExperimental Treatment1 Intervention
Women with GDM diagnosed early (\< 20 weeks gestation) or with routine 3rd trimester screening (\>=24 weeks) will be enrolled in this longitudinal study. All enrolled women will complete a oral glucose tolerance test and wear a continuous glucose monitor for 10 days at the 3 designated study time points (0-4 days, 4-6 weeks, and 6 months after delivery).

Other Research
Common treatments for gestational diabetes include lifestyle modifications, insulin therapy, and continuous glucose monitoring (CGM). Lifestyle modifications, such as diet and exercise, help improve insulin sensitivity and control blood glucose levels. Insulin therapy provides exogenous insulin to manage hyperglycemia when lifestyle changes are insufficient. CGM continuously tracks glucose levels, allowing for real-time adjustments in diet, activity, and insulin dosing. This is crucial for GDM patients as it helps maintain optimal glycemic control, reducing the risk of complications for both the mother and the fetus.
