How to Choose a Bariatric Surgeon in Delhi
Reviewed by Dr. Sushant Wadhera, MBBS, MS (General Surgery), FNB (Minimal Access Surgery) | Delhi Medical Council Reg No. 42170 | Member, European Association for Endoscopic Surgery (EAES) | Last updated: September 2026
Choosing a bariatric surgeon is one of the most important healthcare decisions you’ll ever make. Weight-loss surgery is not just a procedure — it’s a permanent change to your digestive system that requires lifelong follow-up. The surgeon you choose will influence your safety during surgery, your weight loss outcomes, and your quality of life for decades afterward.
Delhi has dozens of doctors advertising themselves as bariatric surgeons. Most patients don’t know how to separate a genuinely qualified specialist from a general surgeon who occasionally performs weight-loss procedures. This guide gives you a clear, honest checklist — the same criteria a well-informed medical professional would use.
The 12-Point Checklist for Choosing a Bariatric Surgeon
1. Verify Medical Council Registration
Every practising surgeon in Delhi must be registered with the Delhi Medical Council (DMC). Ask for the DMC registration number and verify it on the official DMC website. If a surgeon cannot or will not provide this, walk away. (For reference: Dr. Sushant Wadhera’s DMC Registration No. is 42170.)
2. Check Formal Bariatric Surgery Training
Bariatric surgery is a subspeciality — general surgery training alone is not enough. Look for:
- MBBS + MS (General Surgery) — the base qualifications
- FNB or Fellowship in Minimal Access Surgery (MAS) — dedicated laparoscopic training
- Bariatric surgery fellowship — dedicated weight-loss surgery training
A surgeon without formal minimal access surgery training should not be your first choice for a bariatric procedure.
3. Look for International Society Memberships
Membership in international surgical societies indicates ongoing engagement with global best practices. Key memberships to look for:
- EAES — European Association for Endoscopic Surgery
- IFSO — International Federation for the Surgery of Obesity
- OSSI — Obesity and Metabolic Surgery Society of India
- SAGES — Society of American Gastrointestinal and Endoscopic Surgeons
4. Ask About Case Volume
Bariatric surgery outcomes improve significantly with surgeon experience. Published studies show that surgeons performing more than 50 bariatric procedures per year have lower complication rates than lower-volume surgeons. Ask:
- How many bariatric surgeries have you personally performed in total?
- How many do you perform per month?
- How many years have you been performing bariatric surgery?
A surgeon should be able to answer these questions directly, without hedging.
5. Verify Hospital Affiliations
Bariatric surgery requires a well-equipped hospital with an ICU, blood bank, imaging facilities, and a multi-disciplinary team. Ask which hospitals the surgeon operates at, and confirm these are NABH-accredited or JCI-accredited institutions. Multiple hospital affiliations across Delhi NCR are usually a good sign — it shows the surgeon is trusted by different hospital systems.
6. Ask About the Multidisciplinary Team
Bariatric surgery is never a one-person job. Your surgeon should work with:
- An anaesthetist experienced in obesity cases
- A clinical dietitian or nutritionist
- A psychologist or counsellor (recommended pre-surgery)
- An endocrinologist (if you have diabetes)
- Follow-up nursing team
If a surgeon operates in isolation without team support, reconsider.
7. Understand the Full Range of Procedures Offered
A qualified bariatric surgeon should offer multiple procedures — not just push one option on every patient. The right procedure depends on your BMI, medical history, eating patterns, and personal goals:
- Sleeve Gastrectomy — most common, good for BMI 35–45
- Roux-en-Y Gastric Bypass — better for severe reflux or diabetes
- Mini Gastric Bypass — simpler alternative with strong diabetes benefits
- Metabolic Surgery for Type 2 Diabetes — targeted at diabetes remission
- Single-Incision Weight Loss Surgery — for patients wanting minimal scarring
If a surgeon insists you need a specific procedure without discussing alternatives, get a second opinion.
8. Ask About Complication Rates
A confident, experienced surgeon will discuss complication rates honestly. For sleeve gastrectomy, the international standard for major complications is:
- Leak rate: below 2% (published gold standard is around 1%)
- Bleeding requiring re-operation: below 2%
- 30-day mortality: below 0.3%
Ask for the surgeon’s personal complication rates. A surgeon who claims zero complications is either inexperienced or not being honest — every surgeon has some complications, and honesty about them is a green flag.
9. Evaluate the Follow-Up Protocol
Bariatric surgery requires lifelong follow-up — this is non-negotiable. Ask:
- What is the follow-up schedule in the first year? (Standard: 1 week, 1 month, 3 months, 6 months, 12 months)
- What blood tests will I need long-term? (B12, iron, vitamin D, calcium, protein levels)
- What dietary support is included?
- What happens if I have complications 5 years later?
Surgeons who don’t have a structured follow-up plan or discharge you immediately after surgery are a serious red flag.
10. Review Before-and-After Documentation
Ask to see (with patient consent) before-and-after case documentation — not just marketing videos but actual outcomes over 1, 2, and 5 years. Long-term weight maintenance data matters more than dramatic short-term photos.
11. Consider Consultation Quality
Your first consultation tells you a lot:
- Does the surgeon spend adequate time explaining the procedure?
- Are risks discussed as clearly as benefits?
- Are you evaluated for medical suitability (BMI, comorbidities, mental readiness)?
- Are you told “no” if you’re not a good candidate?
A surgeon who says yes to everyone, or rushes through consultation, is not putting your safety first.
12. Check Cost Transparency
Get a written cost breakdown that includes:
- Surgeon’s fees
- Hospital charges (OT, room, ICU if needed)
- Anaesthesia charges
- Pre-operative investigations
- Post-operative follow-ups and dietary consultations
Bariatric surgery in Delhi typically ranges from ₹2.5 lakhs to ₹6 lakhs depending on procedure, hospital, and complexity.
Red Flags to Avoid
Walk away from any bariatric surgeon who:
- Refuses to share their DMC registration number
- Cannot provide their bariatric training background
- Guarantees a specific weight loss outcome (“You will lose 40 kg”)
- Claims zero complications in their career
- Does not have a proper multidisciplinary team
- Discharges you the same day without adequate observation
- Does not have a structured long-term follow-up protocol
- Pressures you to book surgery immediately
- Offers dramatically cheaper prices than the market rate
- Does not evaluate you for psychological readiness
- Is dismissive of your questions or concerns
- Operates in a facility without ICU backup

Frequently Asked Questions
What qualifications should a bariatric surgeon have in Delhi?
A qualified bariatric surgeon should have MBBS, MS (General Surgery), and additional training in minimal access surgery (FNB MAS or equivalent). Membership in international societies like EAES or IFSO indicates ongoing engagement with global best practices. Delhi Medical Council registration is mandatory.
How many bariatric surgeries should a surgeon have performed to be considered experienced?
International guidelines suggest that surgeons performing more than 50 bariatric procedures per year have significantly better outcomes than lower-volume surgeons. Cumulatively, at least 200–300 bariatric cases indicate a well-established practice.
How much does bariatric surgery cost in Delhi?
Bariatric surgery in Delhi typically costs between ₹2.5 lakhs and ₹6 lakhs, depending on the procedure (sleeve gastrectomy is usually less than gastric bypass), the hospital, the surgeon’s experience, and any complications requiring additional care. Always get a written cost breakdown covering surgeon, hospital, and follow-up.
Is bariatric surgery covered by insurance in India?
Many Indian health insurance policies now cover bariatric surgery when medically indicated — typically for patients with BMI above 40, or BMI above 35 with comorbidities like diabetes or hypertension. Check your specific policy and ask the hospital’s insurance desk for pre-authorization support.
How do I verify a bariatric surgeon’s credentials?
Ask for the DMC registration number and verify it on the Delhi Medical Council website. Ask to see certificates of specialised training. Check hospital affiliations on the hospital’s own website. Look for peer-reviewed publications or presentations at recognized conferences.
Should I get a second opinion before bariatric surgery?
Yes — a second opinion is strongly recommended for any major surgery, including bariatric procedures. A qualified surgeon will not be offended by this. It also helps confirm that the recommended procedure is genuinely the best fit for your medical situation.
What’s the difference between a general surgeon and a bariatric surgeon?
All bariatric surgeons are general surgeons by base training, but not all general surgeons are bariatric surgeons. Bariatric surgery requires specialised fellowship training in laparoscopic weight-loss procedures, familiarity with obese patient physiology, and ongoing experience with the specific techniques. Choose someone who focuses on bariatric surgery, not one who does it occasionally.
How do I book a consultation with Dr. Sushant Wadhera?
