Gastric Sleeve in Turkey: Cost, Eligibility & Recovery (2026)

A gastric sleeve in Turkey costs between €2,700 and €5,500 in 2026 as an all-inclusive package in Istanbul — covering the surgery, hospital stay, hotel, transfers and aftercare. The same operation costs €10,000–€14,000 in the UK and €9,000–€15,000 in Germany, which is why thousands of European patients choose Istanbul for bariatric surgery every year.

Gastric sleeve surgery (sleeve gastrectomy, or VSG) is today the most frequently performed weight-loss operation in the world. In this guide, the Firma Clinic team explains what the procedure really costs in 2026, who is a candidate, and what the recovery timeline looks like — so you can make an informed decision.

CountryTypical cost (2026)What you get

All-inclusive package: surgery, hospital, hotel, transfers, aftercare

Patients typically save 60–70% by having the operation in Istanbul — even after flights and accommodation. The price difference reflects Turkey’s lower operating costs and the high volume of bariatric procedures performed here, not lower standards: leading Istanbul hospitals hold JCI and ISO accreditations, the same international benchmarks used by top hospitals in the US and EU.

One important warning: be cautious with offers below €2,000. At that price level, clinics usually cut corners on pre-operative testing, hospital time or aftercare — exactly the elements that keep bariatric surgery safe.

At Firma Clinic, a gastric sleeve package in Istanbul includes:

Full pre-operative assessment: blood panel, ECG, chest X-ray, anesthesia consultation and endoscopy where indicated

The operation performed laparoscopically by an experienced bariatric surgeon in a JCI-accredited partner hospital

3–4 nights in hospital with 24/7 monitoring

3–4 nights in a 4–5 star hotel near the clinic

VIP airport–hotel–hospital transfers

All medications, compression garments and the post-operative leak test

A 12-month nutrition plan with dietitian follow-up

A personal English-speaking patient coordinator from first contact to final check-up

Gastric sleeve surgery is a medical procedure with clear international criteria. You are generally a candidate if:

Your BMI is 40 or higher, or

Your BMI is 35–40 with an obesity-related condition such as type 2 diabetes, hypertension, sleep apnea or joint disease

You are between 18 and 65 years old

You have tried structured diet and exercise programs without lasting results

You do not have an untreated eating disorder or condition that makes general anesthesia unsafe

Patients with a BMI of 30–35 may be considered case by case, particularly with poorly controlled type 2 diabetes. The final decision is always made after your medical file is reviewed by our bariatric surgeon — this review is free and takes less than 24 hours.

The operation is performed laparoscopically through 4–5 small incisions and takes about 60–90 minutes under general anesthesia. The surgeon removes roughly 75–80% of the stomach, leaving a narrow “sleeve” the shape of a banana. The result is twofold: you physically eat smaller portions, and the removal of the stomach’s fundus sharply reduces production of ghrelin — the hunger hormone — so appetite drops as well.

Days 1–3: hospital stay, walking within hours of surgery, liquid intake begins

Days 4–7: hotel recovery in Istanbul, leak test, final surgeon check-up

Day 7–8: fly home

Weeks 1–2: liquid diet; most patients return to desk work within 10–14 days

Weeks 3–4: puréed food

Weeks 5–6: soft food, then gradual return to normal textures; light exercise resumes

Months 12–18: patients typically lose 55–70% of their excess weight

Plan for 7–8 days in Istanbul in total. If you want to know how a treatment trip is organized day by day, read what to expect on your first day at Firma Clinic.

7–8 days: 3–4 nights in hospital and 3–4 nights in a hotel, with the leak test and final check-up before you fly home.

Yes — when performed in an accredited hospital by an experienced bariatric team. Choose clinics operating in JCI or ISO certified hospitals, ask for the surgeon’s case volume, and avoid prices under €2,000.

Most patients lose 55–70% of their excess weight within 12–18 months, provided they follow the nutrition plan. The operation is a tool; the follow-up program is what makes results last.

No. The removed portion of the stomach does not grow back. If needed, the sleeve can later be converted to a gastric bypass, but for most patients no further surgery is ever required.

Most patients self-fund, as bariatric surgery abroad is usually elective. We provide full medical documentation you can submit to your insurer or use for reimbursement claims where applicable.
