Bariatric & Weight-Loss Surgery in India
Laparoscopic sleeve gastrectomy and gastric bypass at accredited Delhi hospitals, for patients managing obesity-related health conditions, with structured nutrition and long-term follow-up built in.
HealPassage connects international patients with NABH-accredited bariatric surgery centres in Delhi offering laparoscopic sleeve gastrectomy, gastric bypass, and adjustable gastric banding. BLK-Max Super Speciality Hospital operates one of Northern India's busiest bariatric programs, with a documented track record of over 600 sleeve gastrectomies and 100+ gastric bypass procedures. Bariatric surgery is generally considered for patients with a BMI of 40 or higher, or a BMI of 35+ with obesity-related conditions like type 2 diabetes, hypertension, or sleep apnea — eligibility is always confirmed by a surgeon, not by cost or convenience. Treatment costs in India are typically up to 80% lower than equivalent private bariatric surgery in the US, UK, or Gulf countries.
Procedures & Conditions
What we help you treat
A detailed look at the obesity-related conditions our partner centres manage, and the surgical procedures available for eligible patients.
Conditions We Help You Treat
Severe Obesity (Class II–III)
A BMI of 35 or higher, particularly when accompanied by obesity-related health conditions, where surgery may be considered after other weight-loss approaches haven't achieved lasting results.
Type 2 Diabetes
Bariatric surgery can significantly improve or, in some cases, lead to remission of type 2 diabetes in eligible patients, alongside weight loss.
Obstructive Sleep Apnea
A condition where breathing repeatedly stops during sleep, often closely linked to excess weight and frequently improving significantly after bariatric surgery.
Hypertension
High blood pressure that is often obesity-related, which can improve substantially following significant weight loss after bariatric surgery.
Non-Alcoholic Fatty Liver Disease
A build-up of fat in the liver associated with obesity, which can improve or stabilize following sustained post-surgical weight loss.
Joint Pain & Osteoarthritis
Excess weight places additional strain on weight-bearing joints; reducing body weight through bariatric surgery can meaningfully ease joint pain and mobility issues.
Procedures Available
Laparoscopic Sleeve Gastrectomy
Minimally InvasiveAbout 80% of the stomach is removed, leaving a smaller, tube-shaped stomach. This reduces food intake and lowers production of ghrelin, the hormone that stimulates hunger. The most commonly performed bariatric procedure.
Gastric Bypass (Roux-en-Y)
Minimally InvasiveA small stomach pouch is created and connected directly to the small intestine, bypassing part of the digestive tract. Restricts food intake and reduces calorie absorption, often used for patients with higher BMI or significant diabetes.
Adjustable Gastric Banding
Minimally InvasiveAn adjustable band is placed around the upper stomach, creating a smaller pouch. The band's tightness can be adjusted over time via a port under the skin, without further surgery.
Revision Bariatric Surgery
SurgicalFor patients who haven't achieved expected results from a prior bariatric procedure, or need adjustment due to complications, requiring specialized surgical planning based on the original procedure performed.
Pre-Surgical Evaluation & Nutrition Counselling
Non-SurgicalComprehensive assessment including BMI, comorbidity screening, and psychological readiness evaluation, alongside dietary counselling to prepare the body for surgery and set expectations for post-op eating habits.
Post-Surgical Follow-Up & Nutrition Support
Non-SurgicalStructured dietary progression (liquid to soft to solid foods), vitamin and mineral supplementation guidance, and ongoing monitoring to support sustainable weight loss and prevent nutritional deficiencies.

Eligibility for bariatric surgery, and which procedure is appropriate, can only be determined by a qualified bariatric surgeon after a full clinical evaluation, including your BMI, medical history, and any obesity-related conditions.

Bariatric Surgery FAQs
Answers to what patients most commonly ask before traveling to India for bariatric surgery.
Am I eligible for bariatric surgery? ＋
Eligibility is generally based on a BMI of 40 or higher, or a BMI of 35+ with an obesity-related condition like type 2 diabetes, hypertension, or sleep apnea — but a surgeon also considers your overall health, prior weight-loss attempts, and psychological readiness. This is a clinical decision made after a full evaluation, not something determined by BMI alone.
Which procedure is right for me — sleeve gastrectomy or gastric bypass? ＋
This depends on your BMI, existing health conditions (particularly diabetes), eating patterns, and surgical risk factors. Gastric bypass is often considered for higher BMI or more significant diabetes, while sleeve gastrectomy is more commonly performed overall. Your bariatric surgeon will recommend the right option after reviewing your specific case.
How much weight will I lose after surgery? ＋
Results vary by individual, procedure type, and how closely post-surgical nutrition guidance is followed — surgery is a tool that supports weight loss, not a guarantee on its own. Your surgical team will give you a realistic range based on your starting point and chosen procedure, rather than a one-size-fits-all number.
What are the risks of bariatric surgery? ＋
As with any major surgery, risks include infection, bleeding, and anesthesia-related complications, along with procedure-specific risks like leaks at the surgical site or nutritional deficiencies over time. These risks are why proper patient selection, an experienced surgical team, and structured follow-up care all matter — your surgeon will walk you through the specific risks relevant to your chosen procedure.
Will I need to take supplements for the rest of my life? ＋
Most bariatric procedures reduce how much of certain vitamins and minerals your body absorbs, so lifelong supplementation (commonly including B12, iron, calcium, and vitamin D) is typically recommended, with the specifics depending on which procedure you have. Regular blood tests help catch and correct any deficiencies early.
Is it possible to regain weight after bariatric surgery? ＋
Yes, some weight regain over the years is possible, particularly if dietary and lifestyle changes aren't sustained long-term. This is exactly why reputable programs build in structured nutrition counselling and follow-up rather than treating the surgery as a one-time fix — ongoing support materially affects long-term outcomes.
How long do I need to stay in India after bariatric surgery? ＋
The hospital stay itself is often just 1-3 days, but we generally recommend planning around 1-2 weeks in India in total, allowing time for your surgeon to confirm you're recovering well and tolerating the post-surgical diet before flying home.
What should I send before a bariatric surgery consultation? ＋
Your current height, weight, and BMI, a summary of any obesity-related health conditions (diabetes, hypertension, sleep apnea), details of previous weight-loss attempts, and any relevant blood work or medical history. This helps the surgical team assess eligibility and outline a plan before you travel.
