Gastric sleeve surgery in Turkey

Gastric sleeve surgery, also known as sleeve gastrectomy, is a popular and effective weight loss solution for individuals struggling with obesity. When diet, exercise, and non-surgical methods like gastric banding haven't worked, bariatric surgery may become a recommended next step.

Patients from the UK, the US and Europe travel to Turkey for gastric sleeve surgery because the all-inclusive package costs less than private treatment at home, and because the larger bariatric centres treat international patients routinely.

Why choose Turkey for weight loss surgery?

Affordable bariatric surgery packages

The cost of gastric sleeve surgery in Turkey is lower than the same operation privately in the UK, the United States and most of Western Europe. The all-inclusive package price for this treatment is shown at the top of this page, together with what it covers.

Highly experienced surgeons

Turkey has a large pool of bariatric surgeons, many trained internationally and working with overseas patients week in, week out. Clinics publish detailed credentials and offer a consultation before you commit, so you can check a surgeon's caseload and qualifications yourself.

English-speaking medical staff

Clinics in Turkey that treat international patients are set up for it. If your surgeon is not fluent in English, a professional translator is normally included in your treatment package so nothing is lost in the consultation.

Comprehensive travel and recovery support

When you book a gastric sleeve package in Turkey, the arrangements are handled for you: flights, accommodation, airport transfers and a recovery hotel. Your coordinator schedules the pre-operative tests, the surgery date and the follow-up appointments so the whole trip runs to one plan.

Gastric sleeve cost in Turkey

The price of gastric sleeve surgery in Turkey depends on the clinic's location, the surgeon's experience, the surgical technique and the type of package you book. The all-inclusive price for this treatment, and what it includes, is shown at the top of this page.

Who is a good candidate for gastric sleeve surgery?

Gastric sleeve surgery is typically recommended for individuals who:

  • Suffer from morbid obesity
  • Have a BMI of 32 or higher
  • Struggle with obesity-related conditions such as:
    • Type 2 diabetes
    • High blood pressure
    • Sleep apnea
    • Heart disease
  • Haven’t had long-term success with traditional weight loss methods

Your doctor will assess your medical history and talk you through the treatment option that suits it.

Who is not a candidate for gastric sleeve surgery

Gastric sleeve surgery is not offered to everyone who asks for it, and a clinic that accepts you without reviewing your history is not doing the assessment properly. A surgeon will usually decline or postpone in the following situations:

  • Your BMI is below the clinical threshold and you have no obesity related condition alongside it
  • You have an untreated eating disorder, or substance dependence that has not been addressed
  • You have a bleeding or clotting disorder, or another condition that makes general anaesthesia unsafe
  • You are pregnant, or planning a pregnancy in the months immediately after surgery
  • You are not in a position to commit to the dietary changes, supplements and follow-up the procedure requires for life

If a surgeon postpones your case, it is usually so a condition can be treated first rather than a refusal outright. Ask what would need to change for you to become a candidate.

Planning your weight loss journey in Turkey

Before travelling abroad for surgery, it’s important to research and prepare carefully. Here’s how to get started:

  1. Verify the surgeon's credentials: look into their education, certifications and years of experience.
  2. Read patient reviews: learn from the experiences of past patients who have had gastric sleeve surgery in Turkey.
  3. Schedule a virtual consultation: most clinics offer this to international patients.
  4. Request a clear quote: understand what is included in the cost, such as surgery, hospital stay and transport.
  5. Ask about aftercare: post-surgery support is what makes recovery go smoothly.
  6. Plan your travel and recovery time: give yourself time to heal comfortably before returning home.

Once you have chosen a clinic, Flymedi arranges your all-inclusive gastric sleeve package in Turkey, matches you with a surgeon whose caseload fits your case, and coordinates the trip from your first consultation to your follow-up appointments.

Gastric sleeve in Turkey: a complete guide

This guide covers gastric sleeve surgery in Turkey end to end: how to prepare, what happens during the operation, what recovery looks like week by week, what a package costs and what it covers, and how to compare clinics. Read it before you request quotes so you know what to ask each provider.

Gastric sleeve recovery timeline in Turkey

Recovering from gastric sleeve surgery involves gradual healing and lifestyle adjustment. Here’s what you can expect during recovery after having the procedure in Turkey:

Step 1: hospital stay, 1 to 3 days

Patients typically stay in the hospital for a few days after surgery to be monitored. Medical staff will check their vitals, manage their pain, and administer any necessary medications.

Step 2: discharge and recovery instructions

Before being discharged, your doctor will provide detailed instructions covering diet, medication, and activity restrictions. Following these guidelines is essential to ensure proper healing.

Step 3: managing pain and nausea

It’s common to experience some discomfort or nausea after surgery. These symptoms are manageable with prescribed medications and following your dietary plan carefully.

Step 4: post-surgery diet progression

You’ll begin with a liquid-only diet, slowly progressing to pureed, soft, and eventually solid foods. A nutritionist or bariatric specialist will guide you through each phase to help your body adapt to the changes.

Step 5: returning to daily activities

Most patients can return to work or light duties within two weeks, depending on the nature of their job. Full recovery typically takes about six to eight weeks.

Step 6: exercise and physical activity

Gentle activities such as walking or light stretching are encouraged to improve blood flow and support healing. Your doctor may also recommend physical therapy to aid mobility and strength.

Step 7: long-term lifestyle changes

Successful weight loss and health improvement require a long-term commitment to healthy eating, regular physical activity, and mental health support. Many patients benefit from joining support groups or working with counsellors during their journey.

What happens during the gastric sleeve procedure?

Gastric sleeve surgery is usually performed laparoscopically under general anaesthesia. The procedure includes the following steps:

  1. Preparation: after anaesthesia is administered, several small incisions are made in the abdomen.
  2. Laparoscopic access: a camera-equipped laparoscope and surgical instruments are inserted through the incisions.
  3. Stomach reduction: a large portion of the stomach is removed, leaving a narrow gastric sleeve.
  4. Closure: the remaining stomach is stapled, and incisions are closed with sutures or surgical glue.
  5. Recovery: the patient is transferred to a recovery area for monitoring until the anaesthesia wears off.

Following surgery, patients must adhere to a structured dietary plan and commit to long-term lifestyle changes. Regular follow-ups are essential to monitor health, nutrition, and mental well-being.

Gastric sleeve cost in Turkey vs the UK

1. Cost comparison

Gastric sleeve surgery in Turkey costs less than the same procedure privately in the UK. The gap comes from lower staffing, facility and living costs in Turkey rather than from any difference in the operation itself, so compare what each quote includes before you compare the totals.

2. Quality of care

Despite the lower cost, many Turkish hospitals maintain high standards and are internationally accredited. Clinics that specialize in medical tourism often provide care tailored to international patients.

3. Hidden costs

When comparing prices, check whether the package includes travel, accommodation, medication, and post-op care. In the UK, private healthcare may include all services at a higher price point.

4. Insurance coverage

Some patients may qualify for coverage through the NHS or private insurance in the UK. In Turkey, procedures are generally paid for out-of-pocket, so it is important to check your insurance options or budget.

5. Balancing cost and quality

While affordability is important, choosing a clinic based on surgeon expertise, hospital credentials, and overall care quality is essential. Safety and long-term success should be your top priorities.

How to reduce the cost of gastric sleeve surgery in Turkey

  1. Choose all-inclusive packages: pick packages that include surgery, hospital stay, accommodation, transfers and follow-up care.
  2. Ask about pricing: many clinics offer better terms for upfront payment or off-season bookings.
  3. Plan travel in advance: book flights early and avoid peak tourist seasons to save on travel costs.
  4. Budget for extras: allow for daily living costs, local transport and any optional services during your stay.
  5. Consider medical tourism insurance: this can cover unexpected complications or cancellations.
  6. Watch exchange rates: change currency when rates are favourable and check for foreign transaction fees.
  7. Planning and research can reduce the overall cost without sacrificing quality or safety.

By combining smart planning, effective negotiation, and thorough research, you can reduce costs without compromising on quality or safety.

Where in Turkey to have gastric sleeve surgery

Turkey is home to several cities known for their excellence in bariatric surgery. Each city offers unique advantages, and your choice may depend on preferences such as location, travel convenience, and clinic offerings.

Cities for bariatric surgery in Turkey

  • Istanbul: the most visited destination, with many internationally recognised clinics and experienced surgeons.
  • Antalya: combines treatment with a quieter recovery environment.
  • Izmir: offers treatment at slightly lower rates.
  • Ankara: the capital city, home to a number of large public and private medical institutions.

When choosing where to have gastric sleeve surgery in Turkey, review clinic accreditations, surgeon credentials, patient reviews and what your package includes. The right clinic is the one that fits your health needs, your travel plans and your budget.

Cost of gastric sleeve surgery in Istanbul

The cost of gastric sleeve surgery in Istanbul varies with the clinic's location, the surgeon's experience, the surgical technique used and whether you need additional treatment. Istanbul has the largest concentration of bariatric clinics in Turkey, so quotes vary more widely there than elsewhere.

What is gastric band surgery?

Gastric band surgery is a less invasive bariatric procedure in which a silicone band is placed around the upper part of the stomach. This creates a small pouch, restricting food intake and promoting weight loss. The band can be adjusted over time by injecting or removing saline through a small port under the skin.

Gastric band cost in Turkey

Adjustable gastric band surgery in Turkey is usually offered as part of a package that includes transport and hotel accommodation. Ask for a written quote showing what the figure covers before you compare it with a gastric sleeve package.

Who gastric band surgery suits

  • Body Mass Index (BMI) of 40+ or 35+ with obesity-related conditions
  • Physically and mentally fit for surgery
  • Have not achieved results through diet, exercise, or other non-surgical methods

How the procedure works

Performed laparoscopically, the surgeon places the adjustable band around the upper stomach. The band slows food intake and prolongs the feeling of fullness, supporting gradual and controlled weight loss. Adjustments are made post-surgery based on the patient’s progress.

Why it is less common today

Gastric banding is no longer widely recommended due to its lower long-term success rate and potential complications such as band slippage, erosion, or infection. Newer procedures like gastric sleeve surgery provide more consistent and lasting results with fewer risks.

What is a minimally invasive gastric sleeve?

A minimally invasive gastric sleeve uses several small incisions rather than one large opening. A laparoscope, a camera-equipped tool, guides the operation through a video monitor. This approach offers several benefits:

  • Reduced pain
  • Lower risk of infection
  • Shorter hospital stays
  • Faster recovery
  • Smaller scars

This approach is widely used in Turkey due to its safety and efficiency.

Other bariatric procedures in Turkey

If a gastric sleeve is not the right fit, compare it with gastric bypass surgery in Turkey, mini gastric bypass in Turkey and gastric balloon in Turkey. If you have already had a sleeve and are considering a second operation, see gastric sleeve revision in Turkey.

Benefits of gastric sleeve surgery in Turkey

Gastric sleeve surgery is one of the most commonly performed bariatric procedures in Turkey. These are the changes patients most often report:

Weight loss after surgery

Gastric sleeve surgery reduces the volume of food the stomach holds at one time, which for most patients means sustained weight loss over the first one to two years. How much you lose depends on your starting weight, your health conditions and how closely you follow the diet and activity plan afterwards.

Effect on obesity related conditions

Weight loss after surgery can improve the following conditions, although this varies between patients:

  • Type 2 diabetes
  • High blood pressure
  • Sleep apnea
  • Heart disease
  • Certain obesity-linked cancers

Day to day quality of life

Many patients experience better physical mobility, improved self-esteem, and a more active lifestyle. These changes often contribute to enhanced emotional and social well-being.

Long term health outlook

Research into bariatric surgery links sustained weight loss with improvement in obesity related conditions. Your surgeon can explain what that evidence means for your own risk profile.

No implant left in the body

Unlike gastric band surgery, gastric sleeve surgery does not involve placing any device inside the body, reducing the risk of complications.

Reduced appetite

A portion of the stomach that produces the hunger hormone ghrelin is removed, which helps decrease appetite and support sustained weight loss.

Choosing a surgeon and hospital you can trust

Gastric sleeve surgery permanently alters your digestive anatomy. It is one of the more consequential healthcare decisions you will make, and the quality of the surgeon and hospital you choose shapes both your safety and your long-term result. Here is what to check.

Board-certified bariatric surgeons

Bariatric surgery requires a specific depth of surgical experience that goes beyond general surgical training. The surgeons available through the Flymedi network are board-certified by nationally or internationally recognised medical authorities, with specialisations in laparoscopic and bariatric procedures. Many have completed advanced fellowship training in metabolic and bariatric surgery and regularly perform high volumes of gastric sleeve procedures each year.

Volume matters in bariatric surgery. Research links higher procedure volumes at a surgeon and hospital level with lower complication rates. When you review a surgeon's profile on Flymedi, you can see their bariatric caseload alongside their qualifications.

JCI-accredited hospitals

Several hospitals in the Flymedi network, including facilities in Istanbul, hold accreditation from the Joint Commission International. Accreditation is assessed against published international standards covering infection control, surgical safety, medication handling and patient rights.

Choosing a JCI-accredited hospital for your gastric sleeve surgery means entering an institution that has been independently assessed against the same international standards applied to hospitals in the UK and the United States.

Verified clinic profiles

Every clinic listed on Flymedi is verified through our own review process before appearing on the platform. Verification covers active registration as a licensed healthcare provider, certification as a health tourism facility by the Turkish Ministry of Health, compliance with international patient care standards, and the availability of English-speaking staff or dedicated medical interpreters for international patients.

You will not encounter unverified listings, inflated credentials, or outdated information on our platform. Clinic profiles are reviewed and updated regularly, and any facility that does not meet our standards is removed.

Patient reviews and ratings

Choosing a bariatric surgeon or clinic on marketing alone is not something we would encourage. Patient reviews are one of the more reliable signals of what your own experience is likely to be.

Every clinic on Flymedi carries a FlymediScore, our own 10-point rating. It is a separate measure from any Trustpilot rating and from the number of reviews a clinic has collected, and the three are never combined. Read the written reviews alongside the score, particularly those from patients who travelled for the same procedure.

Your all-inclusive gastric sleeve journey

Travelling abroad for bariatric surgery involves more than booking a flight and a consultation. You are planning a change that unfolds over the following twelve to eighteen months, and the support around you matters as much as the operation itself.

Your dedicated patient coordinator

When you submit an enquiry through Flymedi, you are assigned a personal patient coordinator, a named individual who manages your case from start to finish. Your coordinator gathers your medical history, arranges your pre-operative assessments and keeps your clinic, hotel and transfers aligned to one schedule.

For bariatric patients in particular, a dedicated coordinator matters. You may be managing other conditions alongside your weight, such as type 2 diabetes, high blood pressure or sleep apnea, and your care plan needs to account for them.

What your all-inclusive package covers

Flymedi's gastric sleeve packages are structured to remove the uncertainty from planning. A standard all-inclusive package typically includes:

  • Pre-operative blood tests and medical assessments
  • All surgical fees, anaesthesia, and theatre costs
  • Hospital stay for the duration required by your procedure, typically two to three nights
  • In-hospital nursing care, prescribed medications, and compression garments
  • Accommodation in a partner recovery hotel for the remainder of your stay
  • Airport, hotel, and clinic transfers throughout your visit, private and scheduled around your programme
  • Nutritional consultation and your post-operative dietary plan before discharge
  • Follow-up consultations with your surgical team prior to your departure

Before you confirm your booking, you receive a complete written quote. The figure you agree to is the figure you pay. There are no hidden fees for standard medical services, no surprise charges for interpreter services, and no ambiguity about what is and is not included.

VIP transfer and hotel accommodation

Recovery from gastric sleeve surgery requires rest, comfort, and the ability to focus entirely on your healing. Flymedi coordinates private VIP transfers between the airport, your recovery hotel, and your clinic at every stage of your visit. You will not be navigating public transport with a post-operative abdomen, managing your own luggage, or waiting in shared vehicle queues.

Your partner recovery hotel is chosen for its proximity to your clinic, its standard of rooms and its experience with medical tourism patients. Many partner hotels are well practised in accommodating post-bariatric patients, including suitable meals during the liquid diet phase.

Aftercare and follow-up

Gastric sleeve surgery is a long-term intervention. The procedure reduces your stomach's capacity permanently, but the lasting work is building new eating habits, managing your nutritional intake, staying active and monitoring your bloods.

Flymedi's aftercare support does not end when you board your return flight. Once you are home, your surgical team remains available for remote follow-up consultations at the key milestones in your recovery, and you receive a written dietary plan to follow.

If you experience a clinical issue during your recovery that requires assessment, your coordinator will help you connect with the appropriate care quickly, whether that means a remote consultation with your Turkish surgical team or guidance on accessing local support in your home country. You are not discharged from care the moment you leave Istanbul. You are supported through the full arc of your transformation.

Risks and side effects of gastric sleeve surgery in Turkey

Some of the possible reactions you can develop after gastric sleeve in Turkey include:

  • Bleeding
  • Infection
  • Blood clots
  • Leakage of digestive contents
  • Injury to adjacent organs
  • Anaesthesia risks
  • The trouble of absorbing certain nutrients

Gastric sleeve results

Weight loss after a gastric sleeve builds over the first two years and varies from patient to patient. The procedure also carries risks, including acid reflux and narrowing of the stomach. Published follow-up data sets out what outcomes have been recorded over time.

What should I expect after gastric sleeve surgery in Turkey?

Recovery from gastric sleeve surgery involves several dietary and lifestyle phases:

Week 1: liquid diet

Stick to low-calorie liquids like broth, protein shakes, and sugar-free gelatin. Avoid solid or soft foods to prevent strain on the stomach.

Weeks 2 to 5: mashed foods

Introduce soft, mashed foods such as pureed vegetables, soft meats, and fruits. Avoid carbonated drinks and processed sugars.

Weeks 6 to 12: soft foods

Add soft cheeses, well-cooked vegetables, and lean proteins. Space meals 4 hours apart and avoid snacking.

After 4 months: regular foods

Begin reintroducing solid foods like meats, eggs, and cooked grains. Some carbohydrate-rich foods may still be difficult to tolerate.

After 2 years: maintenance diet

Calorie intake increases over time based on your progress and tolerance. Your dietitian sets the target for your own plan and adjusts it at your follow-up appointments.

Exercise guidance

Incorporating physical activity before and after surgery helps accelerate weight loss and prevents weight regain. Walking, light resistance training, and stretching are great starting points.

Exercise tip: Regular physical activity before and after surgery boosts weight loss and prevents regaining weight.

In addition to establishing a diet, you should be ready for a certain amount of regular exercise before and after surgery. It will increase the expected weight loss and prevent weight gain.

How to prepare for gastric sleeve surgery in Turkey

  • To ensure a safe and smooth procedure, follow these preparation steps:
  • Stop taking blood-thinning medications like Aspirin at least a week before surgery.
  • Inform your doctor of any drug allergies or medical conditions.
  • Avoid alcohol and smoking in the days leading up to surgery.
  • Follow your doctor’s instructions regarding medication adjustments.

Paying for gastric sleeve surgery in instalments

Medical tourism is an increasingly popular option for individuals seeking high-quality, cost-effective healthcare. For many, the financial burden of upfront payments can be a barrier to accessing treatment abroad. Opting for installment payment plans offers several advantages that make medical treatments more accessible and manageable.

Spreading the cost

  • Spread-out costs: instalment payments let patients spread the cost of treatment over a period, reducing the immediate financial pressure.
  • Wider choice: paying over time can widen the range of clinics and surgeons a patient is able to consider.

Financial flexibility

  • Manageable Payments: Small, predictable monthly payments make it easier to plan and budget without depleting savings or emergency funds.
  • Minimized Debt Risk: Installment plans often have lower interest rates and manageable terms than taking a high-interest loan or maxing out credit cards.

Treating sooner

  • Reduced delays: instalment options remove the need to wait until the full amount is saved.
  • Earlier treatment: treating sooner can stop a condition worsening while you wait.

Peace of mind

  • Financial Security: Knowing payments are spread out and manageable reduces stress and allows patients to focus on their recovery.
  • Transparent Agreements: Many installment plans have clear terms, ensuring no hidden fees or unexpected financial surprises.

By leveraging installment payment plans, individuals can access high-quality medical care abroad while maintaining financial stability. This approach ensures a balance between receiving the best treatment and managing personal finances responsibly.

How Flymedi helps with payment plan options

At Flymedi, we make high-quality healthcare more accessible with flexible installment options tailored to your country. Payments can be spread over up to 72 months (6 years).

Financing options by country

Financing availability and limits differ by country and are set by the lender, not by Flymedi. Your coordinator can tell you which providers operate where you live and what they currently offer.

Financing is also available in Denmark, the Netherlands, Sweden, and other European countries (limits vary).

Interest rates are based on your credit score and are calculated individually by the lender.

Credit card option (Visa, MasterCard, AMEX, Discover): 3, 6, or 12 months installments with a 10% processing fee.

Frequently asked questions

Answers from the medical content team, reviewed by the medical reviewer named on this page.

What is gastric sleeve surgery?
Gastric sleeve surgery, also known as sleeve gastrectomy, is a weight loss operation that removes a large portion of the stomach so it holds less food. What remains is a narrow, tube-shaped sleeve, which limits how much you can eat at one sitting.
Is weight loss surgery in Turkey safe?
Bariatric surgery in Turkey is performed by experienced surgical teams, and many of the hospitals hold international accreditation such as JCI or ISO. Like any operation it carries risks, which are listed in the risks section on this page. Ask your surgeon to talk through the risks that apply to your own medical history.
Why is weight loss surgery less expensive in Turkey?
Treatment in Turkey costs less because staffing, facility and living costs are lower than in the UK or the USA. The operation and the equipment are the same.
How long does a gastric sleeve last?
A gastric sleeve is permanent. The stomach does not grow back to its original size, though it can stretch over time if portion sizes gradually increase. Long-term results depend on diet, activity and follow-up.
How much is a gastric sleeve in Turkey?
The all-inclusive package price is shown at the top of this page along with what it covers. What moves the figure is the clinic's location, the surgeon's experience, the technique used and the type of package you book.
