Examining how menstruation affects blood sugar control and exercise in women with type 1 diabetes
Official title: Impact of MEnstruation on Glycemic Response and Exercise In Females With Type 1 Diabetes
Run by University of Colorado, Denver · NCT06297980 · Data updated 2026-11-12
This study tests how hormonal changes during the menstrual cycle affect blood sugar control and exercise in women with type 1 diabetes to see if adjusting insulin and food intake can help improve their management.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are premenopausal women aged 18-45 with a diagnosis of type 1 diabetes for at least 12 months.
✕Probably not a fit
Patients who are postmenopausal, pregnant, trying to become pregnant, or have had a hysterectomy will not benefit from this study.

What this trial studies
This study investigates the influence of hormonal changes during the menstrual cycle on glycemic control in women with type 1 diabetes. It aims to identify personalized patterns of glycemic variability and test adjustments to insulin dosing and food intake based on menstrual cycle phases. Participants will use continuous glucose monitoring (CGM) to track glucose levels over three months and will undergo a randomized intervention to assess the effectiveness of personalized treatment modifications. The study also evaluates how these hormonal factors affect responses to different types of physical activity.
Why it matters
Potential benefit: If successful, this study could lead to improved glycemic control and better health outcomes for women with type 1 diabetes by personalizing treatment based on menstrual cycle effects.
How similar studies have gone: While the specific focus on menstrual cycle effects in type 1 diabetes is relatively novel, previous studies have shown success in personalized diabetes management approaches.
