Continuous Glucose Monitoring for Pregnant Patients With Gestational Diabetes and Type 2 Diabetes.

Glucose monitoring is arguably one of the most important components of diabetes management in pregnancy. In this review, the application of continuous glucose monitoring (CGM) in managing diabetes during pregnancy is explored with a focus on gestational diabetes mellitus (GDM) and type 2 diabetes (T2D). It highlights the expanding applications of CGM technology, starting with evidence from the landmark CONCEPTT trial. The review examines normative CGM data in uncomplicated pregnancies and emphasizes the emerging evidence for CGM in GDM management. Finally, it addresses the limited but growing data on CGM in T2D pregnancies. Although CGM offers promising new opportunities to overcome the limitations of traditional SMBG testing, knowledge gaps persist. Further research is needed to determine how to effectively use this novel technology in pregnant patients with GDM and T2D to maximize maternal glycemic control and optimize pregnancy outcomes.
