Gastric Sleeve Turkey — Weight Loss Surgery Istanbul from €1,440 — Frequently Asked Questions

At MedProper Istanbul, gastric sleeve surgery starts from £1,925 / $2,455 / €2,250 all-inclusive in 2026. Gastric bypass starts from £2,695 / $3,435 / €3,150. All prices include the surgeon fee, hospital stay (2-4 nights), hotel, VIP transfers, pre-operative tests, medications, supplements, and 12-month aftercare. There are no hidden charges.

The mortality rate for laparoscopic sleeve gastrectomy at experienced, JCI-accredited centres is approximately 0.08 to 0.19 per cent — roughly 1 in 500 to 1 in 1,250, comparable to the rate for laparoscopic gallbladder removal. At MedProper, the risk is further reduced by standardised protocols including intraoperative and post-operative leak tests, Level 3 intensive care availability, and 24-hour monitoring.

Yes, when performed at an accredited facility by an experienced bariatric surgeon. MedProper operates in a JCI-accredited hospital — the strictest international quality standard — with Level 3 intensive care, a named surgeon guarantee, and IFSO-member bariatric specialists. The facility has 450 beds, 18 operating theatres, and 24-hour on-site medical staffing.

The most serious complication is a staple line leak, which occurs in less than 1 per cent of cases at experienced centres. MedProper's dual leak-test protocol (intraoperative and post-operative) minimises this risk. Other rare complications include bleeding, infection, and DVT. Common temporary side effects include nausea, mild pain, fatigue, and hair thinning (which resolves within 12 months).

Most patients lose 60 to 70 per cent of their excess body weight within 12 to 18 months. For example, if you are 30 kg above your ideal weight, you can typically expect to lose 18 to 21 kg. Weight loss continues for up to 18 months, with the most rapid loss in the first 6 months.

The post-operative diet progresses through four phases: clear liquids (days 1-3), full liquids including protein shakes (days 4-14), pureed/blended foods (weeks 3-4), and soft foods (weeks 5-6), before transitioning to regular food in small portions. Protein intake (60 to 80 grams daily) is prioritised throughout. MedProper provides a detailed 12-month nutrition guide.

Yes. A daily multivitamin is recommended for life after gastric sleeve surgery. Unlike gastric bypass, the sleeve does not significantly impair nutrient absorption, so the supplement requirements are less extensive. Your MedProper nutritionist will provide specific recommendations based on your blood work.

At MedProper, patients with BMI 30 to 35 may qualify for gastric sleeve surgery if they have obesity-related comorbidities such as type 2 diabetes, hypertension, sleep apnoea, or PCOS. This is in line with IFSO guidelines. Many UK NHS trusts require BMI over 40, making Turkey a more accessible option.

A banded sleeve combines a standard gastric sleeve with a silicone ring placed around the outside of the stomach at a specific point. The band acts as an additional restriction, reducing the chance of the sleeve stretching over time and potentially improving long-term weight maintenance. MedProper offers banded sleeve from £2,350 / $3,000 / €2,750 all-inclusive.

At MedProper, you stay 2 to 4 nights in hospital after a gastric sleeve. This includes post-operative monitoring, contrast swallow testing to check for leaks, and supervised mobilisation. You then transfer to your partnered hotel for an additional 3 to 5 nights of recovery before flying home.

Most patients fly home 7 to 8 days after surgery. Flights from London to Istanbul take approximately 3.5 hours. From the USA, Turkish Airlines offers direct flights from New York (10 hours), Chicago, Los Angeles, and other major cities. Stay hydrated during the flight, walk the aisle regularly, and continue sipping clear fluids.

Most patients return to desk-based work 2 to 3 weeks after surgery. Physically demanding jobs may require 4 to 6 weeks off. Light walking is encouraged from day one, and moderate exercise can typically resume at 4 to 6 weeks.

No. Gastric sleeve is irreversible because a portion of the stomach is permanently removed. This is an important factor in your decision. However, if the sleeve does not achieve the desired result, it can be converted to a gastric bypass.

Gastric sleeve may worsen pre-existing acid reflux in some patients (approximately 15 to 20 per cent). If you have significant gastroesophageal reflux disease (GORD), your surgeon may recommend a gastric bypass instead, which resolves reflux in over 90 per cent of cases. New-onset reflux after a sleeve is usually manageable with medication.

Yes. MedProper offers both sleeve-to-bypass conversion and re-sleeve procedures for patients who have had a previous gastric sleeve and need revision due to weight regain, sleeve stretching, or severe reflux. Revision surgery requires specialist assessment — contact MedProper for a free evaluation.

MedProper requires a deposit at booking with the balance due before surgery. While MedProper does not directly offer payment plans, many patients use medical finance providers or credit facilities available in the UK and USA to spread the cost. The all-inclusive price from £1,925 makes this far more manageable than the £5,000 to £9,000 typically charged in the UK.

Look for: JCI accreditation (the strictest international standard), a named bariatric surgeon with IFSO membership, on-site Level 3 intensive care, published leak-test protocols, and transparent all-inclusive pricing. MedProper meets all of these criteria and operates in a 55,000 m2 JCI-accredited hospital with 450 beds.
