AI diet coach aims to ease bowel distress after rectal cancer surgery
NCT ID NCT07637565
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether an artificial intelligence-based dietary care app can reduce distress from bowel changes and improve quality of life in rectal cancer patients who have had anal-preserving surgery. One hundred participants will be randomly assigned to either standard dietary education or the same education plus the app for six months. The app uses a large language model for communication and AI to analyze meals from a database of over 100,000 dishes. Researchers will measure bowel function and quality of life at one, three, and six months after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Artificial intelligence-based dietary care system application
- What this could lead to
- If successful, this app could provide a practical, non-drug way to manage bowel symptoms and improve daily life for rectal cancer survivors.
- What could go wrong
- This is a small, early-stage trial with only 100 participants, so results may not apply to everyone. The app requires internet and smartphone access, which may limit use.
