Weight monitoring with a connected scale after bariatric surgery

Evaluation of a Personalized Care Path After Bariatric Surgery Based on Monitoring the Weight Evolution Using a Connected Scale

Not applicable Interventional University Hospital, Lille · NCT04639778

This project tests whether using a connected scale to monitor weight can guide follow-up care for people who had Roux-en-Y gastric bypass or sleeve gastrectomy two years earlier.

What this trial studies

Adults who had Roux-en-Y gastric bypass or sleeve gastrectomy two years ago will be enrolled and assigned to either a usual-care control group or an intervention pathway where follow-up is triggered by weight trends measured at home with a connected scale. The intervention uses patients' home weight recordings transmitted over a wired network to tailor the timing and intensity of multidisciplinary follow-up. Primary outcomes will focus on weight regain and healthcare events such as re-operations and late complications, with follow-up over the postoperative long-term period. Inclusion requires home wired internet access and the ability to use remote monitoring equipment, while patients with major cognitive or psychiatric limitations are excluded.

Who should consider this trial

Good fit: Ideal candidates are adults (≥18) who had Roux-en-Y or sleeve gastrectomy two years earlier, have home wired internet access, and can use a connected scale.

Not a fit: Patients without reliable home internet or who cannot use remote monitoring devices, and those with conditions requiring immediate in-person care, are unlikely to benefit from this pathway.

Why it matters

Potential benefit: If successful, this approach could detect early weight regain and complications, allowing personalized follow-up that may reduce re-operations and improve long-term outcomes.

How similar studies have performed: Remote weight monitoring and telemedicine have shown benefit for weight management in non-surgical populations, but there is limited evidence specifically demonstrating long-term success for postoperative bariatric follow-up.
