The objectives of this study are to examine how sex hormones (use of hormonal birth control, menstrual cycle phase) impact glycemic control among women with type 1 diabetes (T1D), and to test adjustments to insulin dosing and food intake to ameliorate cycle-related glycemic variability. A secondary aim is to examine how the menstrual cycle and use of hormonal birth control impact patient-reported outcomes and glycemic responses to physical activity.
Women 18-45 who have had type 1 diabetes for at least 12 months
Premenopausal with either menstrual cycles or currently using oral contraceptives
Women who are postmenopausal, pregnant, trying to become pregnant, or have had a hysterectomy
