QHow does gastric sleeve compare to gastric bypass?
Gastric sleeve removes the stretchy part of the stomach without rerouting the intestines. It's a simpler bariatric procedure with shorter recovery and fewer nutritional deficiency risks. Gastric bypass is more complex but may suit certain health profiles. Dr. Gmora performs both weight loss surgeries.
