Laparoscopic sleeve gastrectomy (LSG) — colloquially called gastric sleeve surgery — is now the most commonly performed bariatric (weight loss) operation in the world, having overtaken Roux-en-Y gastric bypass as the procedure of choice for the majority of obese patients seeking surgical weight loss. It involves laparoscopic removal of approximately 75–80% of the stomach, converting the original large, J-shaped stomach into a narrow banana-shaped tube (sleeve) of approximately 60–150 mL volume.
Sleeve gastrectomy achieves weight loss through two primary mechanisms: restriction (the dramatically reduced stomach volume limits the amount of food that can be consumed at one sitting); and hormonal (the resected gastric fundus contains the majority of the body's ghrelin-producing cells — ghrelin is the 'hunger hormone' that stimulates appetite; its reduction after sleeve gastrectomy significantly reduces hunger, making dietary compliance much more sustainable than with purely restrictive procedures). Additionally, the sleeve accelerates gastric emptying — rapidly delivering ingested food to the intestine and engaging satiety hormones earlier.
The expected weight loss: approximately 60–70% excess weight loss (%EWL) at 1 year, with typical maintenance of 50–60% EWL at 5 years. The metabolic benefits extend beyond weight — sleeve gastrectomy achieves remission of Type 2 diabetes in 50–60% of patients, significant improvement in hypertension (60–75%), and resolution or improvement of obstructive sleep apnoea (85%).
India and the UAE perform high volumes of laparoscopic sleeve gastrectomy at accredited bariatric surgery centres by surgeons with specific training and certification in metabolic and bariatric surgery.
Sleeve Gastrectomy Candidacy
Sleeve gastrectomy candidacy follows international bariatric surgery guidelines: BMI ≥ 40 (morbid obesity); or BMI ≥ 35 with obesity-related metabolic comorbidities (Type 2 diabetes, hypertension, obstructive sleep apnoea, non-alcoholic fatty liver disease, dyslipidaemia, musculoskeletal disorders); or BMI ≥ 30 with poorly controlled Type 2 diabetes in some guidelines. Age 18–65 is the typical range; selected patients outside these ranges are assessed individually.
Pre-operative evaluation: upper GI endoscopy (assessing for oesophagitis, gastric ulcers, or hiatus hernia — a large hiatus hernia should be repaired at the time of sleeve gastrectomy); routine blood tests (FBC, metabolic panel, HbA1c, thyroid, nutritional markers including iron, B12, folate, vitamin D, zinc); cardiac and pulmonary assessment; dietitian evaluation (baseline dietary assessment and pre-operative diet); and psychological assessment (confirming the patient understands the lifestyle changes required and has realistic expectations).
Sleeve gastrectomy is the preferred procedure over gastric bypass for: patients with severe Crohn's disease or prior bowel surgery that makes bypass anatomy difficult; patients who prefer a simpler procedure with slightly lower complication risk; patients with a primary goal of weight loss rather than maximal diabetes remission (bypass achieves higher diabetes remission rates); and patients in whom the complexity of bypass anatomy is undesirable.
Laparoscopic Sleeve Gastrectomy Procedure
Sleeve gastrectomy is performed under general anaesthesia through 4–5 laparoscopic port sites, taking 60–90 minutes. The patient is positioned supine with a steep reverse-Trendelenburg (head-up) tilt.
The greater omentum (fatty apron of tissue attached to the stomach's greater curve) is divided from the antrum up to the angle of His (the gastro-oesophageal junction), freeing the greater curve of the stomach. The hiatus is inspected; a hiatal hernia is repaired if present. A calibration bougie (40–50 French gauge) is positioned by the anaesthetist into the stomach and down to the pylorus, providing a sizing guide for the sleeve. Beginning at a point approximately 3–5 cm proximal to the pylorus (preserving the pylorus and antrum for normal gastric emptying function), a linear stapler is fired sequentially up the greater curve, closely following the bougie, resecting approximately 75–80% of the stomach. The staple line may be reinforced (with suture or buttressing material) to reduce bleeding and staple line leaks. The resected stomach is removed through an enlarged port site.
The staple line is tested with methylene blue dye or intraoperative endoscopy for leaks. A drain is placed. Port sites are closed; the patient goes to recovery.
Hospital stay is typically 2–3 days. The pre-operative 2-week liquid diet is required to shrink the liver (making the surgery technically easier and safer) and begin the nutritional adaptation process. Post-operative diet progression: liquids for 2 weeks; pureed foods for 2 weeks; soft foods for 2 weeks; then normal diet with portion control.
Procedure Steps
- Pre-operative evaluation: endoscopy, bloods, cardiac clearance, dietitian, psychology
- 2-week high-protein liquid diet pre-operatively (liver shrinkage protocol)
- General anaesthesia; 4–5 laparoscopic ports; reverse-Trendelenburg position
- Greater omentum divided from pylorus to angle of His
- Calibration bougie placed; stapler fired sequentially from antrum to angle of His
- Staple line tested for leaks; drain placed; enlarged port for specimen retrieval
- Discharge day 2–3; post-operative diet progression; vitamin supplementation commenced

India — $4,000 – $6,500 — Best value
Laparoscopic sleeve gastrectomy in the USA costs $15,000–$25,000. In India, LSG costs $4,000–$6,500 all-inclusive (surgeon, anaesthesia, hospital, consumables, and 1-year follow-up visits). For patients with Type 2 diabetes who achieve remission after sleeve gastrectomy, the long-term savings in insulin, oral hypoglycaemic medications, and diabetes-related healthcare costs are significant.
Recovery & Follow-up
Hospital discharge at day 2–3. Return to desk work at 1–2 weeks. Return to moderate physical activity at 3–4 weeks. Full unrestricted exercise at 6–8 weeks. Lifelong vitamin supplementation (multivitamin, vitamin D, vitamin B12, iron, calcium) is required — the reduced stomach volume and altered eating pattern can cause nutritional deficiencies without supplementation. Annual blood tests monitor nutritional status. Follow-up with the bariatric surgery team at 6 weeks, 3 months, 6 months, 1 year, and then annually for 5 years.
Recovery Tips
- Take vitamin supplements as prescribed from day 1 after surgery — deficiencies from inadequate supplementation are a preventable long-term complication
- Drink at least 1.5 litres of water daily in small sips throughout the day — dehydration is the most common reason for early readmission
- Eat protein first at every meal — protein requirements are higher after bariatric surgery and must be prioritised
- Avoid carbonated drinks permanently — the gas causes discomfort and gradually stretches the sleeve
- Walk from day 1 and build activity progressively — exercise significantly improves weight loss outcomes
Risks & Complications
Sleeve gastrectomy risks include: staple line leak (the most serious early complication — 1–3%; typically at the angle of His, managed with drainage and endoscopic or surgical intervention); bleeding from the staple line (1–2%); stenosis of the sleeve (narrowing causing obstruction — managed with endoscopic balloon dilation); gastro-oesophageal reflux disease (GERD) — sleeve gastrectomy can worsen or de novo create GERD in a significant proportion of patients; vitamin and nutritional deficiencies with long-term under-supplementation; DVT/PE; and insufficient weight loss or weight regain (managed by dietary modification and sometimes revision surgery).

Post-operative follow-up is coordinated with the patient's home country primary care physician through a shared care protocol.
Frequently Asked Questions
Will I regain weight after gastric sleeve surgery?
Weight regain after sleeve gastrectomy is an important long-term concern. Most patients achieve maximum weight loss at 12–18 months; some weight regain (typically 10–15% of the excess weight lost) occurs between years 3 and 5 as the stomach slightly stretches over time and adaptive eating behaviours emerge. Patients who commit to long-term lifestyle changes — high-protein diet, regular exercise, ongoing behavioural support — maintain significantly better long-term weight loss than those who rely on the surgery alone. For patients who regain significant weight, conversion to Roux-en-Y gastric bypass provides additional metabolic benefit.
Will sleeve gastrectomy cure my Type 2 diabetes?
Sleeve gastrectomy achieves remission of Type 2 diabetes (normal blood glucose without medication) in approximately 50–60% of patients. A further 20–30% achieve significant improvement (reduced medication requirements and better HbA1c). Diabetes remission is most likely in patients with: shorter diabetes duration (< 5 years); no insulin dependence pre-operatively; higher C-peptide levels (indicating residual beta cell function); and greater weight loss. For maximum diabetes outcomes, Roux-en-Y gastric bypass achieves slightly higher remission rates than sleeve gastrectomy — the bypass achieves metabolic benefits through both weight loss and direct hormonal mechanisms (GLP-1 and GIP incretin effects).
Can I become pregnant after gastric sleeve surgery?
Yes, and successful outcomes are common. However, it is recommended to wait 12–18 months after sleeve gastrectomy before attempting pregnancy — this allows weight loss to stabilise and nutritional status to optimise, reducing risks to mother and baby. Pregnancy after bariatric surgery requires careful monitoring by obstetrics and the bariatric team: nutritional supplementation is particularly important (iron, folate, B12, vitamin D); gestational weight gain targets are different from non-bariatric patients; and the reduced stomach volume makes eating adequate calories in late pregnancy more challenging.
