Summary

This study explores whether changes in heart rate, sleep, and activity measured by a person's own smartwatch can predict flare-ups in inflammatory bowel disease (IBD). Six hundred adults with Crohn's disease or ulcerative colitis who already own a compatible device will participate. Researchers will compare wearable data with lab tests and symptom reports to see if digital biomarkers can reliably signal inflammation before symptoms worsen.

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 could lead to a non-invasive early warning system for IBD flares using everyday wearable devices.
What could go wrong: This is an observational study, not a treatment trial. It may not find reliable patterns, and results may not apply to all patients or devices.
