Can a Normal-Weight baseline improve heart risk assessment in type 1 diabetes?
NCT ID NCT06105931
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This study aims to measure heart and metabolic risk markers—such as insulin resistance and fat distribution—in young adults aged 18 to 30 with type 1 diabetes and a body mass index under 25. Researchers will track changes over one year using glucose clamps and meal tests. The goal is to create a reference for how close obesity treatments can bring these markers to normal levels.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could provide a reference for how close GLP-1 obesity treatments bring cardiometabolic risk markers in people with type 1 diabetes to normal levels.
- What could go wrong
- This is a small, early-phase observational study with only 15 participants, so results may not apply broadly. It does not test any treatment directly.
