Detailed Description:

This pilot single site randomized control trial will compare the blood glucose control and participant satisfaction scores of continuous glucose monitoring vs standard glucose checks in pregnant women with a prior diagnosis of Type 2 diabetes. The study population will consist of 40 women who are less than 20 weeks pregnant at time of enrollment who have a pre-pregnancy diagnosis of Type 2 diabetes. Participants will be randomized to one of two treatment arms. Arm 1: Placement of Dexcom G6 continuous glucose monitor for glucose monitoring for duration of pregnancy Arm 2: Continuation of standard glucose finger sticks with placement of a blinded Dexcom Pro G6 continuous glucose sensor for two ten day periods (at enrollment and again at 28-32 weeks gestation) Participant accrual will occur over 18 months at 1 site. Participants will complete 3 study visits, all of which will be in conjunction with previously scheduled prenatal or diabetes visits: at the time of consent (less than 20 weeks gestation), 28-32 weeks gestation, and 2-6 weeks postpartum.. Surveys will be administered at each time point. At the final visit, patients will be asked for participate in a 2-5 minute directed interview as well. Primary Objective To examine the feasibility of completing a study to assess for differences in patient preferences and glucose control between continuous glucose monitoring and standard glucose checks in pregnant patients with Type 2 Diabetes. Secondary Objectives To estimate the effect of continuous glucose monitoring devices placed prior to 20 weeks in pregnancy in patients with Type 2 diabetes on time in range, as measured between 28-32 weeks of pregnancy. To assess patient satisfaction to continuous glucose monitoring during pregnancy To estimate the effect of continuous glucose monitoring on the incidence of neonatal morbidity and mortality.}}
