Using Continuous Glucose Monitoring for Diabetes Mellitus in Pregnancy

Poor glycemic control in pregnant women with diabetes is closely related to the increased risk of adverse pregnancy outcomes. Therefore, it is very important to achieve strict glycemic control to improve maternal and neonatal outcomes. This chapter focuses on the introduction of the clinical application of continuous glucose monitoring (CGM) in pregnant women with diabetes mellitus. We will briefly introduce the clinical characteristics, diagnostic criteria, and glycemic control goals of diabetes mellitus in pregnancy. We will then classify and analyze the recent developments of CGM application in the clinical management of diabetes in pregnancy. We will use four typical cases as illustrations as how to use CGM technology to detect the glycemic variability in pregnant women with diabetes, as well as how to use the CGM data for individualized treatment, and how to improve pregnancy outcomes by CGM technology. The final section offers a clinical and academic prospective of CGM application in this area.
