Wearable sleep trackers reveal how Weight-Loss surgery changes rest
NCT ID NCT07693491
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This study tracks sleep quality in adults with obesity before and one year after metabolic surgery (gastric bypass or sleeve gastrectomy). Participants wear two sleep-monitoring devices for five nights at home and fill out sleep questionnaires and diaries. The goal is to see whether surgery leads to lasting improvements in sleep, beyond what short lab tests can show.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- metabolic surgery (gastric bypass or sleeve gastrectomy)
- What this could lead to
- If sleep quality improves significantly after surgery, this could point toward better ways to manage sleep problems in people with obesity.
- What could go wrong
- This is an observational study with only 50 participants, so results may not apply to everyone. The sleep monitors are not medical devices and may not capture all sleep issues accurately.
