Dedicated bariatric surgery programme at Vivekananda Hospital
Bariatric surgery, also called weight loss surgery or metabolic surgery, is a category of laparoscopic operations that helps patients with severe obesity achieve substantial and lasting weight reduction. Beyond weight loss, bariatric surgery addresses many medical conditions associated with severe obesity including Type 2 Diabetes, high blood pressure, sleep apnoea, fatty liver disease, and joint pain. Vivekananda Hospital's bariatric programme is built around fellowship-trained surgical expertise, a structured multi-disciplinary evaluation process, and long-term follow-up care.
Bariatric surgery is not a quick fix or a cosmetic procedure. It is a major surgical intervention with specific eligibility criteria, a structured evaluation pathway, and lifelong commitments to dietary change, physical activity, and follow-up care. The bariatric team at Vivekananda emphasises realistic expectation-setting, thorough pre-operative evaluation, appropriate procedure selection, safe surgical technique, and the long-term medical and nutritional support essential for sustained results.
Dr. Abhilash N
Dr. Abhilash N leads the bariatric surgery programme at Vivekananda Hospital. He is fellowship-trained in bariatric surgery with experience across all major weight loss procedures including Sleeve Gastrectomy, Gastric Bypass, Mini Gastric Bypass, and Revision Bariatric Surgery. His clinical approach combines dedicated bariatric expertise with broader laparoscopic surgery capability, supported by the multi-disciplinary team at Vivekananda for comprehensive patient care from evaluation through long-term follow-up.
Who is a candidate for bariatric surgery?
Bariatric surgery is considered for adults with severe obesity who have not achieved sustainable weight loss through supervised diet, exercise, and medical therapy. Eligibility is determined through a thorough medical evaluation that considers BMI, associated medical conditions, prior weight loss attempts, and readiness for lifelong lifestyle changes.
Understanding your BMI
Body Mass Index (BMI) is calculated as weight in kilograms divided by the square of height in metres (kg/m²). BMI is one of several factors used to assess eligibility for bariatric surgery. Other factors include waist circumference, body fat percentage, comorbidities, and overall health.
| BMI Range (kg/m²) | Classification | Typical Approach |
|---|---|---|
| Below 18.5 | Underweight | Nutritional evaluation recommended |
| 18.5 to 24.9 | Normal weight | Maintain healthy lifestyle |
| 25.0 to 29.9 | Overweight | Diet, exercise, medical management |
| 30.0 to 34.9 | Obesity Class I | Intensive medical weight loss |
| 35.0 to 39.9 | Obesity Class II | Bariatric surgery considered if comorbidities present |
| 40.0 and above | Obesity Class III (Severe) | Bariatric surgery considered |
Note: These are general guidelines. Individual eligibility is determined by the bariatric team after comprehensive evaluation.
Bariatric procedures performed at Vivekananda Hospital
Vivekananda Hospital performs all major bariatric surgical procedures using laparoscopic (keyhole) technique. The choice of procedure is individualised based on BMI, medical conditions, eating patterns, and personal factors. Each procedure has its own profile of weight loss, metabolic effects, long-term considerations, and recovery requirements.
Laparoscopic Sleeve Gastrectomy
The most commonly performed bariatric procedure worldwide. About three-quarters of the stomach is surgically removed, leaving a narrow, sleeve-shaped stomach that significantly reduces food capacity and alters hunger-related hormones.
How It Works
Reduces stomach volume so the patient feels full with smaller meals. The part of the stomach removed contains cells producing ghrelin, the hunger hormone, which helps reduce appetite.
Procedure Time
Approximately 60 to 90 minutes under general anaesthesia.
Hospital Stay
Typically 2 to 3 days.
Best Suited For
Patients seeking a less complex bariatric option, those with reflux controlled with medication, and patients wanting to avoid intestinal rerouting.
Roux-en-Y Gastric Bypass
A combination restrictive and malabsorptive procedure. A small stomach pouch is created and connected directly to a lower part of the small intestine, bypassing most of the stomach and the first part of the small intestine.
How It Works
Combines reduced stomach size (restriction) with altered nutrient absorption (malabsorption). Produces significant hormonal changes that often improve Type 2 Diabetes rapidly after surgery.
Procedure Time
Approximately 150 to 180 minutes under general anaesthesia.
Hospital Stay
Typically 3 to 4 days.
Best Suited For
Patients with Type 2 Diabetes, severe reflux, higher BMI, and those willing to commit to strict lifelong vitamin supplementation and follow-up monitoring.
Mini Gastric Bypass (OAGB)
One Anastomosis Gastric Bypass is a simpler variant of Gastric Bypass with a single connection between the stomach pouch and intestine instead of two. Growing in popularity in India due to shorter surgery time and effective outcomes.
How It Works
Creates a stomach pouch connected to a loop of small intestine at a single point, providing similar restriction and malabsorption benefits as Gastric Bypass with a less complex surgical technique.
Procedure Time
Approximately 90 to 120 minutes.
Hospital Stay
Typically 2 to 3 days.
Best Suited For
Patients wanting bypass benefits with shorter operative time. Individual assessment considers reflux history and long-term monitoring readiness.
Revision Bariatric Surgery
For patients whose previous bariatric procedure has not achieved expected outcomes or has caused complications. Revision surgery is technically more complex than primary bariatric procedures and requires specialised evaluation.
Indications for Revision
Inadequate weight loss, weight regain after initial success, complications from prior bariatric surgery, severe reflux after Sleeve Gastrectomy, or anatomical issues needing correction.
Revision Options
Conversion of Sleeve Gastrectomy to Gastric Bypass, Gastric Band removal and conversion to another procedure, or re-do of a previous bypass.
Considerations
Revision surgery has higher complexity and slightly higher complication risk than primary bariatric surgery. Thorough pre-operative evaluation is essential.
The multi-disciplinary bariatric team at Vivekananda

Benefits and risks of bariatric surgery
Bariatric surgery offers significant benefits for appropriate candidates, and like any major surgery, it carries risks that must be understood and weighed against the benefits. The bariatric team at Vivekananda discusses both openly with every patient during the evaluation process.
Potential Benefits
- Substantial weight loss for appropriate candidates who adhere to post-operative dietary and lifestyle recommendations
- Improvement in Type 2 Diabetes — many patients experience reduced medication requirements or diabetes remission after surgery, though individual outcomes vary
- Better blood pressure control with reduced antihypertensive medication needs in many patients
- Improvement in obstructive sleep apnoea with reduced CPAP requirement as weight reduces
- Reduced joint pain from reduced mechanical load on weight-bearing joints
- Improved fatty liver disease and reduced cardiovascular risk markers
- Better mobility, energy levels, and quality of life reported by most patients
- Relief from obesity-related social and psychological burdens in many patients
Surgical Risks & Considerations
- Surgical risks — bleeding, infection, blood clots, anaesthesia reactions, rarely staple-line or anastomotic leak
- Nutritional deficiencies — vitamin and mineral deficiencies requiring lifelong supplementation (particularly vitamin B12, iron, calcium, vitamin D)
- Dumping syndrome — after Gastric Bypass, high-sugar or high-fat foods can cause sweating, palpitations, diarrhoea
- Weight regain — possible if dietary and lifestyle changes are not maintained long-term
- Need for revision surgery — a small proportion of patients may need revision over the years
- Gallstones — rapid weight loss can trigger gallstone formation; cholecystectomy may be needed
- Hair thinning and skin changes during rapid weight loss phase
- Long-term commitment to follow-up visits, blood tests, and supplementation is essential
