Alternatives
Gastric bypass (Roux-en-Y)
Better for severe GERD or BMI 50+. Higher complication rate but more durable weight loss long-term.
GLP-1 medications (Wegovy, Zepbound)
No surgery; lifelong medication. Comparable weight loss for many but weight regain is high after stopping.
Gastric balloon (Orbera, Allurion)
Endoscopic, removable at 6 months. Modest weight loss (10–15%); high regain rate after removal.
