First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how menstrual cycles and birth control pills impact blood sugar levels and exercise in women with type 1 diabetes. Researchers will monitor 150 women for three months using continuous glucose monitors and offer personalized insulin and diet adjustments. The goal is to find better ways to manage glucose during different phases of the menstrual cycle.

- Personalized insulin and diet adjustments
- What this could lead to
- If successful, this could lead to better blood sugar control for women with type 1 diabetes by tailoring treatment to their menstrual cycle.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly test a new drug or cure. Results may not apply to all women with type 1 diabetes.
