Can hypnosis help when Weight-Loss surgery fails?
NCT ID NCT03485469
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial investigates whether adding hypnosis sessions to standard dietary monitoring can help people lose weight after bariatric surgery has not worked. About 25% of patients do not achieve lasting weight loss from surgery alone. The study enrolls 60 adults aged 18-65 with obesity who have failed bariatric surgery and cannot have a second surgery. Participants receive 10 hypnosis sessions focused on relaxation, emotional management, and self-esteem, alongside usual dietary care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hypnosis sessions
- What this could lead to
- If it works, this could offer a non-surgical option to help patients who did not lose enough weight after bariatric surgery.
- What could go wrong
- This is a small early-stage study with only 60 participants, so results may not apply to everyone. Hypnosis may not lead to significant weight loss for all.
