Glycemic Control During the Menstrual Cycle in Women With Type 1 Diabetes: Performance of an Automated Insulin Delivery System
Authors' conclusion
Women with T1D using an AID system demonstrated phase-dependent differences in glycemic control, with lower time in range and greater hyperglycemia during the LLP and a higher susceptibility to hypoglycemia during the early follicular phase, accompanied by higher prandial insulin requirements.
