Gastric sleeve surgery in Turkey costs between £3,000 and £5,500 — compared to £8,000–£15,000 at a private UK clinic, and with NHS waiting lists now stretching to several years. For UK patients who have exhausted other options, Turkey has become the most realistic route to life-changing bariatric surgery. This guide explains exactly what to expect: the cost, the process, the recovery, and how to choose a clinic you can trust.
What Is Gastric Sleeve Surgery?
Gastric sleeve surgery — medically known as sleeve gastrectomy — is a bariatric procedure that permanently reduces the size of the stomach by approximately 75–80%. The surgeon removes the outer curved portion of the stomach laparoscopically (through small keyhole incisions), leaving a narrow tube or "sleeve" shape. This restricts food intake and reduces hunger by removing the part of the stomach that produces ghrelin, the hunger hormone.
Unlike gastric bypass, there is no rerouting of the intestines. This makes the gastric sleeve technically simpler, with a lower complication rate and faster recovery, while still delivering substantial long-term weight loss results.
How Much Does Gastric Sleeve Surgery Cost in Turkey?
All-inclusive gastric sleeve packages in Turkey — covering surgery, anaesthesia, hospital stay, pre-operative tests, and aftercare — typically range from £3,000 to £5,500. This compares to £8,000–£15,000 at UK private hospitals, where additional costs (consultations, follow-up dietitian, bloods) are often billed separately.
| Cost Component | Turkey (all-inclusive) | UK Private | |---|---|---| | Gastric sleeve surgery | Included | £8,000–£12,000 | | Hospital stay (2–4 nights) | Included | £1,000–£3,000 extra | | Pre-op blood tests & scans | Included | £300–£600 extra | | Anaesthesia | Included | Often separate | | Nutritional counselling | Included | £100–£200 per session | | **Total estimated cost** | **£3,000–£5,500** | **£10,000–£18,000** |Prices are estimates for 2026.

Am I Eligible for Gastric Sleeve Surgery?
Gastric sleeve is indicated for patients who meet specific clinical criteria. Standard eligibility guidelines (based on NHS and IFSO recommendations) are:
- BMI of 40 or above — eligible regardless of other conditions
- BMI of 35–39.9 with one or more obesity-related conditions (type 2 diabetes, hypertension, sleep apnoea, joint disease)
- BMI of 30–34.9 in certain cases — assessed individually, particularly where diabetes or metabolic syndrome is present
- Previous attempts at medically supervised weight loss that have not produced sustained results
- No active alcohol or substance dependency
- Psychologically fit for surgery — assessed by a pre-operative consultation
Tour Medical's bariatric team carries out a full pre-operative assessment — including blood tests, cardiac evaluation, and dietary review — before confirming eligibility. This is done remotely in advance of travel, so there are no surprises when you arrive.
The Gastric Sleeve Process at Tour Medical: Step by Step
Step 1: Free Online Consultation (Before Travel)
Your journey begins with a free remote consultation with Tour Medical's UK-liaison team. You share your current weight, BMI, medical history, and any medications. The bariatric coordinator reviews this information and provides an initial eligibility assessment within 24 hours.
Step 2: Pre-Operative Tests (Day 1 in Kusadasi)
On arrival, you are admitted to the hospital for a comprehensive pre-operative work-up: full blood panel, liver function tests, ECG, chest X-ray, abdominal ultrasound, and an anaesthesiology consultation. These are completed the same day and included in the package price.
Step 3: Surgery (Day 2)
Gastric sleeve surgery at Tour Medical's partner hospitals in Kusadasi is performed laparoscopically under general anaesthesia by a specialist bariatric surgeon. The procedure takes approximately 60–90 minutes. You are moved to a private recovery room after surgery and monitored overnight.
Step 4: Hospital Stay (2–4 Nights)
Most patients remain in hospital for two to four nights post-surgery. During this period you progress from liquids to a pureed diet under the supervision of the clinical team. Pain is managed with IV medication initially, transitioning to oral analgesics. The nursing team carries out regular blood pressure, blood sugar, and wound monitoring throughout.
Step 5: Pre-Discharge Dietitian Session and Aftercare Pack
Before discharge, a registered dietitian conducts a one-to-one session covering your dietary phases (liquid, pureed, soft, solid), supplement requirements (protein, vitamin B12, iron, calcium), and long-term eating habits. You receive a written aftercare pack and ongoing remote access to the dietitian via WhatsApp for 90 days post-surgery.
Step 6: Transfer and Return Home (Day 5–7)
Most patients are discharged and fly home five to seven days after arrival. Tour Medical arranges airport transfer and provides a medical clearance letter for your airline if required. Your UK GP receives a full surgical report.
Gastric Sleeve Recovery: What to Expect
Recovery from gastric sleeve is progressive. Here is a general timeline:
- Days 1–7: Liquid diet only (water, clear broths, protein shakes). Fatigue, mild discomfort, and bloating are normal. Light walking encouraged from Day 2.
- Weeks 2–4: Transition to pureed and soft foods. Most patients return to desk-based work at Week 2–3. No driving for the first two weeks.
- Weeks 4–8: Transition to soft solid foods. Energy levels improve significantly. Light exercise (walking, swimming) can resume.
- Months 2–6: Solid foods reintroduced progressively. Weight loss typically 2–4 kg per month. Gym and structured exercise from Month 2–3.
- Month 12: Most patients have lost 50–70% of their excess body weight. Long-term dietary habits and supplementation are well established.
Expected Weight Loss After Gastric Sleeve
The gastric sleeve produces significant and sustained weight loss in the majority of patients. Clinical data shows:
- Average excess weight loss of 60–70% within 12–18 months
- Resolution or significant improvement of type 2 diabetes in approximately 60% of patients
- Improvement in hypertension, sleep apnoea, and joint pain in the majority of cases
- Long-term weight maintenance when combined with dietary and lifestyle changes
Tour Medical's aftercare programme — including remote dietitian access, a structured supplement protocol, and a 90-day check-in schedule — is designed to maximise these outcomes for UK patients returning home after surgery.

Frequently Asked Questions
How much does gastric sleeve surgery cost in Turkey in 2026?
All-inclusive gastric sleeve packages in Turkey typically cost between £3,000 and £5,500, covering surgery, hospital stay, pre-operative tests, anaesthesia, and aftercare. This compares to £10,000–£18,000 at UK private hospitals where many costs are itemised separately.
Is gastric sleeve surgery safe in Turkey?
Yes — at accredited facilities with certified bariatric surgeons. Tour Medical's partner hospitals in Kusadasi hold Ministry of Health certification and are staffed by surgeons with specialist bariatric qualifications. Complication rates at experienced bariatric centres are comparable to those in the UK.
How long do I need to stay in Turkey for gastric sleeve?
Most patients stay for five to seven days in total: one day for pre-operative tests, one to two days for surgery and initial recovery, and two to three additional nights of hospital monitoring before discharge and return home.
Will my UK GP be informed about my surgery?
Yes. Tour Medical provides a full surgical report — including procedure details, discharge summary, and supplement protocol — for your UK GP. You are encouraged to register your surgery with your GP on return so that ongoing blood monitoring can be coordinated locally.
What is the difference between gastric sleeve and gastric bypass?
Gastric sleeve removes approximately 75–80% of the stomach volume without rerouting the intestines, resulting in restriction of food intake and a reduction in hunger hormones. Gastric bypass additionally reroutes the small intestine, producing stronger metabolic effects and greater weight loss, but with a higher complexity and longer recovery. Your bariatric consultant will recommend the most appropriate procedure based on your BMI, medical history, and goals.
