Conditions

Gestational Diabetes Mellitus (GDM)

Brief summary

This is a prospective pilot study to assess the validity of using a continuous glucose monitor (CGM) in diagnosing gestational diabetes mellitus (GDM). Pregnant individuals between the ages of 18-50 years old receiving prenatal care at Mount Sinai Hospital (e..g, E-Level clinic and Faculty Practice Associates) will be enrolled. Potential participants will be approached during their prenatal care appointments. Participants will complete an informed consent form for the study during their standard-of-care prenatal appointments at our institution.

Interventions

DEVICEContinuous glucose monitor

Device is a remote sensor applied to the upper extremity that continuously samples glucose of interstitial fluid and uploading results to a mobile application.

Design outcomes

Primary

MeasureTime frameDescription
Blood glucose from CGM10 days from sensor application to completion of testingBlood glucose aggregate values from Dexcom G7 continuous glucose monitor (CGM)
Glucose Tolerance Test (GTT) values1 hour and 3 hours1-hour GTT values and 3-hour GTT values The glucose tolerance test is a lab test to check how the body moves sugar from the blood into tissues like muscle and fat. The test is used as standard of care to diagnose gestational diabetes.
Postpartum blood glucose4 hours after childbirthA blood sugar test measures the amount of a sugar called glucose in a sample of blood.
