Bariatric Surgery in Turkey 2026: Gastric Sleeve, Bypass, and Costs

Everything you need to know about weight loss surgery in Turkey. Gastric sleeve vs bypass, real costs, top Istanbul clinics, and how to prepare.

Turkey has become the world’s leading destination for bariatric surgery. Over 50,000 weight loss procedures are performed on international patients in Turkey every year — more than any other country. The reasons: costs 70–80% lower than the UK or US, JCI-accredited hospitals, and highly experienced bariatric teams.

Weight Loss Surgery Costs: Turkey vs Other Countries

Procedure UK USA Turkey
Gastric sleeve (VSG) £8,000–15,000 $15,000–25,000 $3,500–6,000
Gastric bypass (RYGB) £12,000–20,000 $20,000–35,000 $5,000–8,000
Gastric band £6,000–10,000 $12,000–20,000 $3,000–5,000
Mini gastric bypass £10,000–16,000 $18,000–28,000 $4,500–7,000
Revision surgery £15,000–25,000 $25,000–40,000 $5,500–9,000

Most Turkish clinics include hospital stay, pre-op tests, and post-op follow-up in the price.

Gastric Sleeve vs Bypass: Which Is Right for You?

Gastric Sleeve (VSG) — 70–80% of the stomach is removed, leaving a small tube (“sleeve”). Simpler procedure, no rerouting of intestines. Most popular bariatric procedure worldwide.

Gastric Bypass (RYGB) — stomach is divided into a small pouch and connected directly to the small intestine, bypassing most of the stomach and upper intestine. More complex but more powerful.

Mini Gastric Bypass (MGB) — a simpler version of bypass with one connection instead of two. Increasingly popular in Turkey due to good outcomes and lower complication rates than RYGB.

Week 1–2: Clear liquids only (water, broth, protein shakes) Week 3–4: Puréed foods Week 5–6: Soft foods Month 2+: Regular food, small portions, high protein

This progression is crucial — eating solid food too early risks complications. Your clinic will provide a detailed protocol.

Flying home: most surgeons allow flying 5–7 days after sleeve, 7–10 days after bypass. Use compression stockings and walk every hour on the flight.

Long-term Success Factors

Surgery is a tool, not a cure. Long-term success requires:

Patients who follow the protocol consistently lose 70–80% of excess weight and maintain it at 5 years. Those who don’t may regain weight.
