Bariatric Surgery at Nanavati Max Hospital

Bariatric surgery, or metabolic surgery, is a category of life-saving operations designed to treat class III obesity by modifying the digestive system. These procedures work by reducing gastric capacity (restriction), altering nutrient absorption (malabsorption), or a combination of both. Unlike traditional weight loss methods, bariatric surgery rewires the body’s metabolic programming, significantly reducing hunger hormones like ghrelin while increasing satiety signals.

Obesity is a chronic, relapsing disease that is not just about excess weight. It is a primary driver of major health complications such as Type 2 diabetes, hypertension, heart conditions, and obstructive sleep apnea. For people who have not seen success with diet, exercise, or medications, undergoing weight loss surgery in Mumbai at Nanavati Max Hospital offers a superior, durable alternative to temporary treatments. It not only helps in significant weight loss but is also the most effective treatment for the remission of many obesity-related health conditions.

Who Qualifies for Bariatric Surgery? (Eligibility Criteria)

In India, the Obesity and Metabolic Surgery Society of India (OSSI) provides specific guidelines tailored to the Asian-Indian phenotype, which carries higher metabolic risks at lower BMI levels.

You may be a candidate for fat loss treatment through surgery if:

• BMI ≥ 35: Candidates with or without associated comorbidities.
• BMI ≥ 32.5: Candidates with at least two obesity-related conditions (e.g., Diabetes, Hypertension).
• BMI ≥ 27.5: May be considered for metabolic surgery in cases of uncontrolled Type 2 Diabetes.
• Waist Circumference: ≥ 90 cm for men and ≥ 80 cm for women with associated health risks.

Types of Bariatric Surgery We Offer

1. Sleeve Gastrectomy (Gastric Sleeve)

This procedure involves surgically removing approximately 80% of the stomach, leaving a narrow tube or "sleeve." This not only limits food intake but also removes the portion of the stomach responsible for producing the hunger hormone ghrelin. It is suitable for individuals with moderate to severe obesity and offers significant long-term weight loss benefits with a lower risk of internal hernias compared to bypass surgery.

2. Roux-en-Y Gastric Bypass (RYGB)

Commonly regarded as the "Gold Standard," a small portion of the stomach is separated to form a 30ml pouch, which is then attached directly to the small intestine. This bypasses a part of the digestive system, reducing both food intake and calorie absorption. It triggers powerful hormonal changes that can lead to immediate improvement in blood sugar levels.

• Pros: Rapid weight loss; up to 80% Type 2 Diabetes remission.
• Cons: Risk of Dumping Syndrome; requires lifelong Vitamin B12, Calcium, and Iron supplements.

3. One Anastomosis Gastric Bypass (Mini Gastric Bypass)

This surgery involves creating a long gastric tube and joining the small intestine to it in a loop fashion, creating only one junction (anastomosis). This reroutes food directly to the small intestine, promoting malabsorption. It is recommended for patients with Class III obesity. While effective, it carries a higher risk of bile reflux and requires lifelong nutritional follow-up.

4. Single Anastomosis Sleeve Jejunal Bypass (SASJ-S)

SASJ-S combines sleeve gastrectomy with a simplified bypass of the intestines. It is a modern metabolic procedure that helps with both weight loss and diabetes control while allowing for future endoscopic access to the biliary tract.

Understanding the Risks and Complications

While bariatric surgery in Mumbai is safer than ever—with complication rates lower than gallbladder removal—patients must be aware of potential risks:

• Anastomotic Leaks: A rare but serious complication (1-2%) where fluid leaks from the surgical connection.
• Dumping Syndrome: Rapid gastric emptying causing nausea, dizziness, and sweating after consuming high-sugar foods.
• Nutritional Deficiencies: Anemia or bone density loss due to malabsorption of iron and calcium if supplements are missed.
• Gallstones: A common side effect of rapid weight loss, often managed with temporary medication post-surgery.

Benefits and Expected Outcomes

• Significant and sustainable weight loss (typically 60-70% of excess body weight).
• Resolution of Metabolic Syndrome (diabetes, high blood pressure).
• Enhanced physical mobility and reversal of joint pain.
• Significant reduction in the risk of cardiovascular death.
• Improved mental health and reduction in clinical depression symptoms.

Safety Protocols and Recovery Process

Every patient at Nanavati Max undergoes a strict pre-surgical evaluation to ensure procedural success.

• Pre-Surgical Evaluation: Every patient undergoes a mandatory cardiac clearance, pulmonary function test (PFT), and a psychological readiness assessment.
• Recovery Timeline:
• Hospital Stay: 2 to 3 days for monitoring.
• Return to Desk Work: Within 1 to 2 weeks.
• Dietary Progression: Clear liquids (Weeks 1-2), Pureed foods (Weeks 3-4), Soft solids (Month 2+).
