Weight Loss Surgery

Why Istanbul Is a Leading Destination for Bariatric Surgery

Turkey performs more than 80,000 bariatric procedures per year, placing it among the top three destinations globally. Istanbul hosts dozens of bariatric centers accredited by international bodies aligned with the ASMBS and IFSO. Package prices for sleeve gastrectomy, Roux-en-Y gastric bypass and endoscopic gastric balloon are 50–70% lower than the United Kingdom, Germany or the United States, while the staplers and balloons come from the same manufacturers (Ethicon Echelon, Medtronic Signia, Orbera, Allurion).

Mapa Health partners exclusively with Turkish Ministry of Health-licensed centers that run dedicated bariatric programs with nutritionists, psychologists and 12-month post-op follow-up. Every plan starts with a free BMI assessment and returns a written surgeon recommendation within 24 hours.

Compare Bariatric Procedures: Sleeve vs Bypass vs Balloon

Procedure choice depends on BMI, comorbidities (diabetes, reflux), desired weight loss and reversibility preference. Side-by-side comparison:

*EWL = Excess Weight Loss. Results vary by patient adherence to post-op nutrition and lifestyle.

Who Qualifies for Bariatric Surgery (NIH/ASMBS Criteria)

• BMI 40 or higher (morbid obesity) — eligible for any bariatric procedure.
• BMI 35–39.9 with comorbidities — type 2 diabetes, hypertension, obstructive sleep apnea, severe reflux, osteoarthritis, fatty liver disease.
• BMI 30–34.9 with uncontrolled type 2 diabetes — per updated 2022 ASMBS/IFSO guidelines.
• BMI 27–35 — gastric balloon is the non-surgical option.

Contraindications: pregnancy, active eating disorder, uncontrolled psychiatric illness, active substance abuse, inability to adhere to long-term nutritional supplementation.

Pre-op Preparation: The Liver-Shrinking Diet

Two weeks before surgery, a high-protein low-carbohydrate diet (typically <800 kcal/day) reduces fatty liver size and makes laparoscopic access to the stomach safer. Adherence is critical — an enlarged liver is the single most common reason for procedure conversion.

• ✔Lean protein: chicken breast, fish, egg whites, low-fat Greek yogurt.
• ✔Non-starchy vegetables: leafy greens, broccoli, cucumber, peppers.
• ✔No bread, pasta, rice, potato, sugar, fruit juice, alcohol.
• ✔Minimum 2 liters of water + electrolyte supplementation.

Post-op Diet Progression (Sleeve & Bypass)

• Days 1–3: clear liquids (water, broth, sugar-free drinks, diluted fruit juice).
• Week 1: full liquids (protein shakes, soups, milk, yogurt).
• Weeks 2–3: pureed high-protein foods.
• Week 4: soft solids (well-cooked vegetables, flaked fish).
• Month 2 onwards: regular textures, emphasizing protein (60–80 g/day). Lifelong multivitamin + B12 + iron + calcium + D3 supplementation.
