Read our Type 1 Diabetes research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research study is investigating how your menstrual cycle affects your blood sugar levels when you exercise. Researchers want to understand whether blood sugar behaves differently during different phases of your cycle in women with Type 1 diabetes who take monophasic oral contraceptives. This information could help you and your healthcare team better predict and manage your blood sugar during physical activity.
Women with Type 1 diabetes often experience unpredictable changes in blood sugar during exercise, and hormones from the menstrual cycle may play a role in these variations. By studying how these hormonal phases affect exercise response, researchers hope to develop better strategies to help women manage their diabetes more safely and effectively during workouts.

You will visit the lab twice, about a week apart—once during your active birth control pills and once during your placebo pill week. At each visit, you'll exercise on a stationary bike for 45 minutes while researchers monitor your blood sugar through a sensor placed on your belly and blood samples taken through an IV. You'll also need to keep your food and insulin as consistent as possible between visits and avoid strenuous exercise and alcohol the day before and after each session.
