Your watch and grocery list could spot IBD flares early
NCT ID NCT07159776
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether data from a wearable device and grocery loyalty cards can help detect disease flares in people with Crohn's disease or ulcerative colitis. Eighty adults will wear a smartwatch and use a store card to track their health and food purchases. The goal is to develop digital markers that signal worsening disease without extra clinic visits.
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 way to detect IBD flares early using everyday data like heart rate and grocery purchases, helping doctors adjust treatment sooner.
- What could go wrong
- This is an early observational study with only 80 participants. The digital signals may not reliably predict flares, and results may not apply to all patients.

Who is studied
This is an open label observational trial with partially blinded data collection (wearable and shopping data blinded for the patient and treating HCP). Patients in the study will not be randomized. Patients will be recruited via planned outpatient visits and day clinic admissions. Patients will be allocated to one of the three target patient groups at the investigator's discretion. 1. Patients with IBD in longstanding remission (\>2 years) (maximum of 20 patients) 2. Patients with IBD recent event (diagnosis or flare of IBD) (\<1year) (minimum 20 patients) 3. Additional patients with IBD in standard follow up. From the moment 60 patients are included, no additional patients can be recruited in group 1 or 3 prior to completion of group 2.

Inclusion Criteria: * Males or females aged \> 18 years * Diagnosis of CD, UC or IBD-unspecified for at least 1 month * Treatment with conventional or advanced therapy for IBD at initiation of the study * The patient must have access to an email address * The patient must be willing to perform all the groceries shopping at any of the Colruyt Group stores during this study, using an Xtra card created by the study team. * Capacity to independently answer regular digital questionnaires * Capacity and willingness to use a smartphone and activity tracker Exclusion Criteria: * Planned extended (\> 1 month) overseas travel during the study period of 12 months, if internet access would be impossible, inconvenient or unaffordable during this time * Previous colectomy * Inability to communicate well with investigators or unable to comply with the study requirements * Significant medical condition interfering with physiological measurements trough a wearable device (heart failure, pacemaker or defibrillator) * Inclusion or planned inclusion in an interventional IBD-related clinical trial
