Sleeve Gastrectomy (also called gastric sleeve) is a minimally invasive weight-loss operation. Surgeons remove roughly 75-80% of the stomach, leaving a tube-shaped pouch.
The procedure is performed laparoscopically through 4-5 small incisions and typically requires 60-90 minutes.
The mechanism combines two effects: physical restriction of food intake and hormonal changes that reduce hunger signals. The intestines remain intact, distinguishing it from bypass procedures.
The surgery targets individuals with severe obesity (BMI ≥40, or ≥35 with related conditions like diabetes or sleep apnea) who haven't achieved results through conservative methods.
It's also used as a first-stage operation for extremely high-BMI patients.
Expected outcomes include:
Major complication rates range from 3-6%, with mortality around 0.1% (1 in 1,000).
Specific risks include:
Diet progression:
Lifelong care: Vitamin supplementation and regular follow-up required.
