Summary
This study compares how two weight-loss surgeries—gastric bypass and sleeve gastrectomy—affect acid reflux in 128 obese patients. Participants will be randomly assigned to one surgery, and their reflux will be measured before and after using a 24-hour pH test. The goal is to see which surgery causes less worsening of reflux, helping doctors make better treatment choices.
