How Menstruation Affects Blood Sugar and Exercise in Females with Type 1 Diabetes

This study wants to see how blood sugar changes with sex hormones during regular menstrual cycles or when using hormonal birth control. We also want to learn how exercise and hormonal birth control affect blood sugar.

Why this Research Matters

This study wants to learn more about how blood sugar is controlled during the menstrual cycle. We will enroll 180 women with Type 1 Diabetes, ages 18 to 45. Of these women, 120 will have regular periods and 60 will be using hormonal birth control. We want to have the same number of active women and women who are not active.

What to Expect

If you join, for the first three months, you will continue your usual exercise and diabetes management. You will wear a continuous glucose monitor and physical activity tracker. You will track your menstrual cycle, insulin, food, and activity. After 3 months, you will have a 1-month break. Then, you will be randomly picked to either get a plan to help manage your diabetes based on your menstrual cycle, or continue with your regular care. You will have four in-person visits. During these visits, you will fill out surveys, answer health questions, and have your vitals checked. We will also take a small sample of blood from your arm with a needle to check your blood sugar and hormone levels.

You will be in the study for about 8 months
