What is a Laparoscopic Sleeve Gastrectomy?
Laparoscopic Sleeve Gastrectomy (LSG) is a metabolic and bariatric surgical procedure where approximately 80% of the stomach is surgically removed, leaving a narrow tube or "sleeve" shaped like a banana. This restricts food intake and significantly reduces the production of Ghrelin (the "hunger hormone"), helping patients achieve significant and sustained loss of excess body weight.
Who Needs Sleeve Gastrectomy?
Surgery is indicated for individuals struggling with severe obesity who have been unable to achieve sustainable weight loss through diet and exercise alone.
Key clinical indicators include:
- Body Mass Index (BMI) ≥ 35 kg/m² with obesity-related comorbidities (Type 2 Diabetes, Hypertension, Sleep Apnea, Fatty Liver).
- BMI ≥ 40 kg/m² regardless of comorbidities.
- Failure of structured non-surgical weight loss attempts.
- Commitment to long-term dietary and lifestyle modifications.
How Sleeve Gastrectomy Works
- Restrictive Effect: Smaller stomach capacity limits the amount of food consumed at one time.
- Hormonal Effect: Removal of the stomach's fundus drops Ghrelin levels, suppressing appetite and improving insulin sensitivity.
Benefits of Sleeve Gastrectomy
- Expectation to lose 60% - 70% of excess body weight within 12 - 18 months.
- Remission or significant improvement in Type 2 Diabetes, hypertension, and sleep apnea.
- No rerouting or bypass of the intestinal tract, preserving natural nutrient absorption pathways.
- Reduced joint pain and improved physical mobility.
What to Expect Before Surgery?
Preparation involves a multidisciplinary team evaluation:
- Comprehensive Workup: Blood tests, Endoscopy, Abdominal Ultrasound, Cardiac and Pulmonology clearance.
- Pre-Op Liquid Diet: 1-2 weeks of high-protein liquid diet to shrink liver size for safer laparoscopic access.
- Nutritional & Psychological Counseling: Mental preparation for permanent dietary habits changes.
Complete Procedure
- Administration of general anesthesia.
- Insertion of laparoscopic ports through 4 to 5 small abdominal incisions.
- Separation of blood vessels along the greater curvature of the stomach.
- Calibration of sleeve size using an endoluminal bougie tube.
- Longitudinal division and stapling of the stomach using laparoscopic surgical staplers.
- Removal of the severed stomach portion through one of the port sites.
- Intraoperative leak test to verify staple line integrity.
What to Expect During Surgery?
The procedure takes about 60 to 90 minutes. You will be fully unconscious under general anesthesia. Post-surgery, you will stay in the high-dependency unit (HDU) or ward for recovery and vitals monitoring.
Sleeve Gastrectomy vs Gastric Bypass
| Feature | Sleeve Gastrectomy | Roux-en-Y Gastric Bypass |
|---|---|---|
| Intestinal Rerouting | None | Yes (Bypasses part of intestine) |
| Dumping Syndrome Risk | Rare | Higher |
| Surgical Complexity | Moderate | High |
| Excess Weight Loss | 60% - 70% | 70% - 80% |
Success Rate and Safety
Sleeve Gastrectomy is safe with a complication rate under 2-3%. Long-term weight maintenance success exceeds 85% when combined with lifestyle compliance.

| Deluxe / Super-Deluxe Suite | ₹4,00,000 - ₹5,50,000 |
Disclaimer: Packages generally include staplers, bariatric team fees, hospital stay, and routine post-op dietetics.
Recovery Guide & Post-Operative Care
Post-Op Diet Progression
- Week 1-2: Clear liquids only (water, broth, protein water).
- Week 3-4: Pureed and blended foods.
- Week 5-6: Soft foods (eggs, mashed vegetables, minced fish/chicken).
- Month 2 Onwards: Transition to solid high-protein, low-carbohydrate small meals.
Post-Op Precautions & Care
- Daily Supplements: Lifetime daily multivitamins, calcium, and B12 supplementation.
- Hydration: Sip fluids slowly throughout the day (1.5 - 2 liters daily); do not drink during meals.
- Exercise: Daily walking starting Day 1; light workouts starting Month 1.
Frequently Asked Questions
Is Sleeve Gastrectomy reversible?⌄
No, sleeve gastrectomy is permanent because the removed portion of the stomach is removed from the body.
How much weight can I expect to lose?⌄
Most patients lose about 60% to 70% of their excess body weight within the first 12 to 18 months.
Will I have sagging skin after losing weight?⌄
Depending on age, genetics, and total weight lost, some skin looseness may occur, which can be addressed with exercise or body contouring later.
When can I return to work after sleeve gastrectomy?⌄
Most patients return to desk jobs within 10 to 14 days post-surgery.
Can the sleeve stretch over time?⌄
Yes, if you consistently overeat, the sleeve can stretch slightly. Adhering to portion control guidelines prevents this.
