Step 1 of 4
What is gastric sleeve surgery and how does it work?
Sleeve gastrectomy is a permanent bariatric operation in which around 80% of the stomach is removed, leaving a narrower sleeve-shaped stomach. The intestines are not rerouted, so food continues along the natural digestive route.
The smaller stomach supports fullness after smaller portions. Effects on hunger and metabolism are not explained by stomach size alone, but surgery remains a tool used alongside nutrition, movement and long-term clinical follow-up—not a stand-alone cure.
≈80%Approximate stomach portion removed
KeyholeUsually a laparoscopic approach
PermanentNon-reversible anatomical change
Who may be considered for gastric sleeve in Turkey?
Suitability is not decided by BMI alone. NICE recommends specialist bariatric assessment for adults with a BMI of 40 or more, or 35–39.9 with a significant health condition that could improve with weight loss. Some international guidance may consider lower thresholds in selected people.
✓
Weight-management history and previous attempts
✓
Type 2 diabetes, blood pressure, sleep apnoea and joint problems
✓
Reflux, stomach conditions and previous operations
✓
Current medicines and anaesthetic risk
✓
Nutrition status and eating patterns
✓
Readiness for long-term follow-up and lifestyle change
Important:
An online form or BMI result is not surgical approval. The final decision follows surgeon and anaesthetic review plus the tests required for your case.
Is gastric sleeve in Turkey safe? Outcomes, benefits and risks
No operation or destination is automatically safe. Personal risk depends on your health, the right procedure, surgeon and hospital experience, a documented complication plan, enough time in Turkey and follow-up after you return home.
Many patients may lose around 60–70% of excess weight during the first 12–18 months. Type 2 diabetes, high blood pressure, sleep apnoea, mobility and quality of life may improve, but outcomes vary and cannot be guaranteed.
Potential benefits
- Fullness after smaller portions
- Potential for substantial, durable weight loss
- Improvement in obesity-related conditions
- No intestinal rerouting
Potential risks
- Bleeding, leak and infection
- Blood clots and anaesthetic complications
- New or worsened reflux
- Narrowing, gallstones and nutrient deficiencies
- Insufficient weight loss or weight regain
Detailed safety guide: Risks, death-rate context and provider checklist
Recovery, nutrition and long-term follow-up
Fluids and short walks begin when the clinical team considers it safe. Food is advanced in stages to protect healing. Timing can vary with your individual recovery, so your discharge plan always takes priority.
01
Liquids
Water and clear or protein-containing fluids approved by the team.
02
Puréed stage
Smooth, small portions eaten slowly.
03
Soft foods
A gradual move to protein-first, easy-to-chew options.
04
Balanced routine
Long-term portions and supplements guided by your dietitian.
Decision centre
Compare gastric sleeve with the main alternatives.
The purpose is not to recommend one option to everyone, but to make anatomy, permanence and the questions that need clinical discussion visible.

The least invasive or most powerful-looking option is not necessarily the right one for every person. Reflux, diabetes, previous surgery, medicines, nutritional risk and ability to maintain follow-up are assessed together.

Recovery week by week
From preparation to lifelong follow-up.
The stages are a general roadmap. Your timing depends on operative findings, fluid tolerance, related conditions and the discharge plan given to you.
Preparation
Your individual pre-operative plan
Medicines, smoking or nicotine, current conditions and any prescribed liver-reduction diet are planned individually by the team.
Day 0
Surgery and close monitoring
Observation, pain and nausea control follow anaesthesia; movement begins when the clinical team considers it safe.
Days 1–2
Fluid and walking goals
Small sips, short walks and discharge criteria are assessed by the hospital team.
Week 1
Approved liquid stage
Water and clear or protein-containing fluids specified by the team, with intake and tolerance as priorities.
Week 2
Full liquids and smooth textures
Protein-first smooth options and slow intake according to Aylin Demir’s individual plan.
Weeks 3–4
Puréed and soft foods
New textures are tested one at a time in small portions while avoiding rushed eating and protecting fluid intake.
Months 2–3
Moving towards a balanced routine
Protein, portions, movement, supplements and personal tolerance are adjusted with the dietitian.
Months 6–12
Blood tests and behaviour follow-up
Monitoring covers vitamins and minerals, muscle-loss risk, reflux and sustainable habits—not only the weight curve.
Lifelong
Annual clinical and nutrition review
Supplements, blood tests and signs of weight regain remain part of long-term care.

A first screening step
Calculate your BMI.
BMI is only one part of a gastric sleeve assessment. Use the result as a starting point for a conversation about your medical history.
Your result—
Enter your height and weight for a screening BMI estimate.
BMI is a screening measure, not a diagnosis or a decision about surgery. Medical history, related conditions, nutrition, previous weight-management attempts and surgeon assessment are also required.
Typical patient journey
From Istanbul arrival to home aftercare.
This is an example itinerary. Your final travel and treatment plan follows clinical assessment.
Arrive in Istanbul
Airport welcome, private transfer and travel to the hospital or hotel according to your written plan.
Tests and surgery
Blood tests, ECG, ultrasound, anaesthetic and surgeon review are completed before surgery for accepted patients.
Hospital recovery
Fluids, mobilisation, pain control and clinical observation progress according to your individual recovery.
Hotel and final review
Move to the partner hotel after discharge, then complete your final check and receive a written care plan.
Fly home and aftercare
Continue with dietitian guidance, coordinator contact and remote surgical follow-up when required.
After you return to the UK
Take your follow-up and urgent-care plan home.
Leave with your discharge summary, operation record, medicine list, test results, surgeon and hospital details, plus routine and urgent contact routes. Seek urgent medical help for symptoms such as severe abdominal pain, breathlessness, a fast heart rate, fever, persistent vomiting or inability to keep fluids down.
