Sleeve Gastrectomy
What is Sleeve Gastrectomy?
Sleeve Gastrectomy is one of the most widely performed bariatric procedures globally. It is a permanent weight loss surgery that involves removing approximately 70–80% of the stomach, leaving behind a slender, sleeve-shaped stomach that resembles a banana.
This smaller stomach not only restricts food intake but also significantly reduces hunger by eliminating the part of the stomach that produces ghrelin, the “hunger hormone.”
Key Features of the Procedure
- Performed laparoscopically or robotically for minimal scarring, shorter hospital stays, and faster recovery.
- Preserves digestive tract anatomy with no rerouting of the intestines.
- Lower risk of nutrient deficiency compared to malabsorptive weight loss surgeries.
- Naturally reduces hunger and enhances satiety for effective appetite control.
Who is it recommended for?
1. individuals with morbid obesity (BMI ≥ 40) or BMI ≥ 35 with comorbidities like:
- Type 2 Diabetes
- Hypertension
- PCOS
- Sleep Apnea
2. Ideal for younger patients and as a first-stage surgery for individuals with very high BMI (60+)
3. Not suitable for those with:
- Severe GERD (acid reflux)
- Large hiatal hernias
Benefits of Sleeve Gastrectomy
