What is a gastric sleeve?

Sleeve gastrectomy is a bariatric operation in which a large part of the stomach is removed, leaving a narrower sleeve-shaped stomach. It is usually performed through keyhole surgery. The operation is intended to support earlier fullness and long-term weight management, but it is not a stand-alone cure for obesity.

The right question is not simply whether the operation can be performed. It is whether sleeve gastrectomy is the most appropriate option for your health, eating pattern, reflux history, previous treatment and ability to follow a long-term nutrition plan.

How suitability should be assessed

NICE recommends a comprehensive, multidisciplinary assessment before bariatric surgery. This includes medical conditions, nutritional status, eating behaviour, psychological needs, previous weight-management attempts and fitness for anaesthesia and surgery.

  • Your weight and weight-management history
  • Type 2 diabetes, high blood pressure, sleep apnoea and other related conditions
  • Reflux symptoms and previous abdominal surgery
  • Current medicines, smoking and alcohol use
  • Nutrition, eating behaviour and readiness for postoperative changes
  • Your arrangements for follow-up after returning to the UK

How much is a gastric sleeve in Turkey?

The current all-inclusive gastric sleeve package is £1,800 for patients whose assessment confirms this pathway. It is coordinated with Istanbul Obesity Center and lists the planned operation and hospital stay, preoperative examination and tests, hotel accommodation, VIP transfers, package medicines and supplements, interpreter support and planned follow-up.

The written quotation should name the partner hospital, list every inclusion and exclusion and state what happens if further tests, a longer stay or treatment for a complication becomes necessary. Flights and specialist insurance are not described as included unless expressly stated in the individual plan.

  • Named surgeon and hospital
  • Preoperative tests, anaesthesia and hospital nights
  • Medicines, dietetic support and planned follow-up
  • Hotel, transfers and companion arrangements
  • Items that are excluded, including flights, insurance or an extended stay

Is gastric sleeve in Turkey safe?

No bariatric operation is risk-free. Safety depends on individual assessment, appropriate procedure selection, the experience of the operating team, the hospital's resources and a clear plan for recognising and treating complications.

Before paying, confirm who will operate, where the operation will take place and who will provide clinical advice after discharge. Ask how the team prevents blood clots and responds to bleeding, infection, dehydration or a suspected staple-line leak.

  • A named surgeon who has assessed your case
  • Anaesthesia, critical-care, imaging, endoscopy and laboratory support
  • Written protocols for blood clots, bleeding and suspected leaks
  • Direct clinical contact after discharge and an emergency pathway
  • An English discharge pack and coordinated follow-up after returning to the UK

What should an all-inclusive package explain?

An all-inclusive label should never replace an itemised plan. Confirm exactly which medical services, hospital nights, accommodation, transfers, medicines, dietetic reviews and remote appointments are included. Flights and specialist travel insurance are often separate, while extended stays and complication-related treatment may create additional costs.

Travel arrangements should follow the clinical plan. Do not select a procedure because it fits a package, and do not book the earliest return flight before an individual fit-to-fly assessment.

Benefits, limits and risks

Weight loss surgery can support substantial health improvement in appropriately selected patients. Results vary, and no responsible provider should guarantee a particular amount of weight loss.

As with any operation, sleeve gastrectomy carries risks. These include bleeding, blood clots, infection, a leak from the stomach staple line, reflux and nutritional problems. Your personal risk should be discussed before you commit to surgery, together with alternatives such as medical weight management or another bariatric procedure.

The long-term commitment

A smaller stomach changes how you eat, but long-term success also depends on nutrition, physical activity, supplementation and follow-up. NICE recommends at least two years of follow-up within a bariatric service and lifelong annual nutritional monitoring after discharge into shared care.

Before travelling, ask exactly who will review your blood tests, how you will contact the surgical team and how care will be coordinated with your GP or another UK clinician.

What to prepare for an online assessment

A structured first assessment is easier when the clinical team receives accurate information rather than only your height and weight.

  • Recent blood results and a current medicine list
  • Relevant GP or specialist letters
  • Previous endoscopy, imaging or operation reports
  • A clear history of reflux, sleep apnoea and previous weight treatment
  • Questions about hospital care, complications, nutrition and UK follow-up
