Using a connected scale to help keep weight off after bariatric surgery

Connected Scales to Optimize the Maintenance of Weight Lost After Bariatric Surgery and Limit Failures and Reoperations

Not applicable Interventional Assistance Publique - Hôpitaux de Paris · NCT06133413

This study will test whether weekly home weigh-ins with a connected Body Comp Pro scale can help people about one year after sleeve or gastric bypass surgery avoid regaining more than 10% of their lost weight.

What this trial studies

This open, randomized study will enroll 182 patients about one year after sleeve gastrectomy or Roux-en-Y gastric bypass and follow them for 12 months. Participants are randomized 1:1 to standard follow-up or standard follow-up plus weekly weighing using the Body Comp Pro connected scale with alerts sent to the clinical team through a secure platform. The primary aim is to compare the proportion of patients who experience excessive weight regain (more than 10% of lost weight) between the two groups. The trial uses remote patient monitoring to improve follow-up intensity during the post-nadir weight maintenance period.

Who should consider this trial

Good fit: Adults aged 18 or older who had sleeve gastrectomy or Roux-en-Y gastric bypass about 12 months (±1 month) before enrollment, are covered by social security, and can read and speak French.

Not a fit: Patients who cannot stand on a scale, have a pacemaker, require intensified medical/surgical monitoring at inclusion, are pregnant or planning pregnancy during participation, are legally protected, deprived of liberty, or enrolled in another interventional study are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this approach could help patients maintain weight loss and reduce the need for additional interventions or reoperations.

How similar studies have performed: Remote monitoring with connected scales and weight telemonitoring has shown promise in other weight-management contexts, but its specific effect on post-bariatric surgery weight regain is not yet well established.
