Summary

This study follows 75 people who had either sleeve gastrectomy or gastric bypass for severe obesity. Researchers track acid reflux symptoms, esophageal damage, and other measures for 8 years using tests like endoscopy and pH monitoring. No new treatments are given—it's purely observational to see how GERD changes over time after each surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to

If successful, this study could clarify which bariatric surgery is better for long-term GERD control, helping guide future treatment decisions.

What could go wrong

This is an observational follow-up, not a new treatment trial. Results may not apply to all patients, and GERD can still worsen over time regardless of surgery type.
