About

Gestational diabetes (GDM) is one of the most common complications of pregnancy, and up to one third of women with GDM will have abnormal blood sugars after their pregnancy. To screen for abnormal blood sugars, standard of care is a 4-12 week postpartum oral glucose tolerance test (OGTT). However only 17-60% of women actually have this test performed. This study is to assess continuous glucose monitor data from the third trimester and up to 14 days postpartum to find predictors of postpartum OGTT results.

Full description

Those with GDM in current pregnancy using a Dexcom Continuous Glucose Monitoring (CGM) are eligible for enrollment. Participants use their CGM as usual during pregnancy and wear one sensor postpartum. They have their standard of care OGTT performed at around 6 weeks. They then complete a remote questionnaire after OGTT.
