Source: ClinicalTrials.gov · Last updated 20 Jul 2026
Brief summary (registry, in English)
Female participants with type 1 diabetes using oral contraceptives will be asked to wear a continuous glucose monitor for at least three days on two separate occasions (once during the last week of active pills and once during the no pill/placebo pill phase of the menstrual cycle). An exercise session (45 minutes of aerobic exercise at 60% VO2peak on a cycle ergometer) will take place at 5 pm on the second day of glucose monitoring.
