Gastric Sleeve in Turkey

Gastric sleeve surgery, also called sleeve gastrectomy, is a metabolic and bariatric operation that removes a large portion of the stomach and leaves a narrow sleeve-shaped stomach.

Information only Antalya
Quick answer

Gastric sleeve surgery, also called sleeve gastrectomy, is a metabolic and bariatric operation that removes a large portion of the stomach and leaves a narrow sleeve-shaped stomach. It can affect food intake, fullness and metabolic signalling. Suitability requires individual medical assessment and long-term follow-up.

Information, not advice

This page is general information and contains no prices, no before-and-after promises and no recommendation. Suitability, technique, recovery and travel timing can only be determined after a medical assessment at the authorised health facility.

What Is Gastric Sleeve Surgery?

Sleeve gastrectomy removes a substantial portion of the stomach, leaving a narrow tube or sleeve. It does not create an intestinal bypass, but it can affect appetite, fullness and metabolic responses while reducing the amount that can be eaten comfortably at one time.

The operation is irreversible because removed stomach tissue is not replaced. The decision therefore requires assessment of medical history, eating patterns, medications, nutritional status and expectations. Long-term diet, activity and clinical review remain important.

What May Gastric Sleeve Be Considered For?

  • Clinically significant obesity when bariatric surgery is appropriate after assessment.
  • Weight-related health conditions that may improve with sustained weight reduction and metabolic change.
  • Individuals for whom a procedure without intestinal bypass is clinically appropriate.
  • Cases in which another bariatric procedure is not considered the preferred first option.
  • Patients prepared to follow a structured nutrition, activity and follow-up programme after surgery.

International bariatric guidance uses BMI alongside health conditions and the wider clinical picture. BMI alone does not determine the correct operation; the treating bariatric team makes the final decision after individual assessment.

Who May Not Be Suitable?

  • People with untreated conditions that significantly increase procedural risk.
  • Individuals unable to follow postoperative dietary stages or long-term nutritional monitoring.
  • Patients with active substance misuse or uncontrolled eating disorders until appropriately assessed and managed.
  • People with certain gastrointestinal conditions where sleeve gastrectomy could aggravate symptoms.
  • Anyone for whom another strategy is safer or more appropriate.

Reflux deserves particular attention because sleeve gastrectomy may worsen existing gastro-oesophageal reflux or cause new symptoms in some patients. Upper gastrointestinal evaluation may therefore be considered when clinically indicated.

Preoperative Assessment Before Gastric Sleeve

  • Medical history, previous operations and current medications.
  • Blood tests and nutritional screening, with deficiencies corrected when required.
  • Assessment of obesity-related conditions such as diabetes, sleep apnoea or hypertension.
  • Dietetic review and preparation for staged postoperative eating.
  • Anaesthetic and surgical risk assessment.
  • Additional imaging, endoscopy or specialist review when the clinical picture requires it.

How Is Gastric Sleeve Performed? Step by Step

  1. Anaesthesia and preparation

    The operation is performed under general anaesthesia with appropriate monitoring and preventive measures.

  2. Laparoscopic access

    Small abdominal incisions are generally used for a camera and surgical instruments; anatomy or previous surgery may change the approach.

  3. Mobilising the stomach

    The stomach is carefully separated from surrounding attachments so the planned portion can be safely divided.

  4. Creating the sleeve

    A sizing guide may be used while surgical stapling devices divide the stomach vertically. A large portion of the stomach is removed, leaving a narrow sleeve-shaped stomach.

  5. Safety checks

    The staple line and surrounding structures are inspected. The team may use additional tests or reinforcement according to clinical judgement and institutional protocol.

  6. Closure and early monitoring

    After closure, hydration, pain, mobilisation and tolerance of the planned liquid intake are monitored before discharge is considered.

Recovery and Diet Progression

StageWhat It May Involve
Immediately after surgeryMonitoring focuses on breathing, circulation, pain, nausea, hydration and early mobilisation. Oral intake begins only according to the treating team's protocol.
Early daysA staged liquid plan is commonly used. Patients are advised to take small amounts slowly and follow medication and wound-care instructions.
Following weeksFood texture is gradually advanced from liquids to smoother and then more solid foods according to clinical guidance. Portions remain small.
Longer termThe focus shifts to protein intake, balanced nutrition, hydration, physical activity, laboratory monitoring and supplements when prescribed.
OngoingWeight, symptoms, nutritional markers and obesity-related conditions should be reviewed over time. Follow-up is part of the treatment, not an optional extra.

Possible Risks and Considerations

  • Bleeding, infection or adverse reactions associated with surgery or anaesthesia.
  • Leak from the gastric staple line, which requires urgent medical assessment.
  • Blood clots and pulmonary complications.
  • Narrowing, obstruction or persistent intolerance of food or fluids.
  • New or worsening acid reflux and heartburn.
  • Vitamin, mineral or protein deficiencies if intake and supplementation are inadequate.
  • Gallstones during periods of rapid weight change.
  • Insufficient weight reduction or later weight regain, which may require additional management.

Any severe abdominal pain, persistent vomiting, breathing difficulty, fever, fast heart rate, inability to drink or other unexpected deterioration after surgery requires prompt medical evaluation.

Planning Gastric Sleeve in Turkey

International patients need a plan covering assessment, surgery, postoperative review and clearance for onward travel. Relevant medical records and medication information should be shared before travel, and return flights should follow the treating team’s advice rather than a generic package duration.

  • Carry an updated medication list and relevant previous medical reports.
  • Confirm who provides postoperative medical contact before leaving Turkey.
  • Follow the healthcare team's guidance on mobility, hydration and thrombosis prevention during travel.
  • Arrange local follow-up and laboratory monitoring after returning home.
  • Seek urgent medical care rather than waiting for remote advice if warning symptoms develop.

Frequently Asked Questions

No. Sleeve gastrectomy removes part of the stomach, so it is considered an irreversible anatomical change.
No. Food continues through the usual intestinal route, although the stomach itself is substantially smaller.
Yes. Reflux can develop or worsen in some patients, so pre-existing symptoms should be discussed during assessment.
Supplement needs depend on the clinical plan and laboratory findings, but long-term nutritional monitoring is important.
Suitability and procedure choice are determined by qualified healthcare professionals after individual medical, nutritional and surgical assessment.

“From the very first message to the flight home, everything was handled by one coordinator. The airport pickup was on time, the interpreter came to every appointment, and whenever a detail changed we were told in writing within the hour. Travelling abroad for a procedure could have felt overwhelming, but the steady, organised communication kept the whole experience calm and genuinely manageable for us.”
AKA. K.
🇬🇧 United Kingdom
“Everything was on time, every single time, and the communication stayed calm and clear from start to finish. Before we left home the coordinator walked us through the schedule, the transfers and who to contact at each step. Having one organised point of contact for all the arrangements made a foreign trip feel far less daunting than I had expected.”
MRM. R.
🇩🇪 Germany
“They shared the full programme in writing before we travelled, so my husband and I could plan everything around it without any guesswork. Each day was laid out with transfer times and the documents we needed to carry. Whenever we had a question the reply came quickly and in plain language, which made the whole arrangement feel organised and completely transparent.”
SVS. V.
🇳🇱 Netherlands
“Very well organised from beginning to end, and when a small hotel change came up it was sorted within hours without any fuss. The coordinator kept me updated at every stage and always confirmed the details in writing. I never had to chase anyone for information, which is exactly what you hope for when you are arranging a trip in another country.”
JDJ. D.
🇮🇪 Ireland
“We travelled as a couple and were nervous about the language and all the logistics involved. As the companion, I was given my own briefing with pickup times, the numbers to call and what to bring. Everything was written down clearly, so at no point did we feel lost or left to work things out on our own in an unfamiliar place.”
LPL. P.
🇧🇪 Belgium
“Someone answered every message quickly, even late in the evening, which made a real difference when we were far from home. The team explained each step of the arrangements clearly and never left a question hanging. Knowing there was always a reliable person to reach out to gave us a lot of reassurance throughout the whole trip.”
NTN. T.
🇬🇧 United Kingdom
“The accommodation was a short walk from the facility, and the driver was waiting exactly where they said he would be. Every transfer had been thought through in advance, so we simply followed the plan we had been given. It is the kind of careful organisation that quietly removes all the small worries you would otherwise carry on a trip abroad.”
HBH. B.
🇩🇪 Germany
“What stood out most was the honesty of the whole team. Nobody pushed us towards anything or made promises they couldn't keep. Every question about the process was answered plainly, and when something was for the facility to decide, they told me so directly instead of guessing on their behalf. That straightforwardness is why I felt comfortable throughout.”
EÇE. Ç.
🇫🇷 France
“The visa and document checklist they sent ahead of time saved me a great deal of stress. Everything I needed to prepare was listed in one place and explained step by step, so I arrived with all my paperwork in order. Having that kind of clear guidance before departure made the entire journey feel organised and well within my control.”
RMR. M.
🇦🇹 Austria
“Coordinated from door to door, so I always knew exactly who to contact and what the next step would be. The schedule was shared with me early and updated whenever anything shifted, all in clear writing. Having a single organised point of contact for the travel and appointments took the guesswork out of a trip that could easily have been confusing.”
