Brief summary
The aim of this observational study is to assess the effectiveness of automatic insulin infusion in responding to changes in insulin sensitivity throughout various phases of the menstrual cycle in a cohort of reproductive-aged women with type 1 diabetes, using an advanced closed-loop system. By gaining insights into both the limitations and effectiveness of this adaptation, we aim to inform the enhancement of control algorithms and learning strategies within closed-loop systems. This research is especially vital for addressing the distinct challenges that women commonly encounter in maintaining glycemic control.
