Gastric Sleeve in Turkey

Gastric sleeve surgery, also called sleeve gastrectomy, is a weight-loss operation in which a large part of the stomach is removed, leaving a narrow, tube-shaped stomach. It is usually performed laparoscopically through several small incisions. The smaller stomach limits how much food can be eaten at once, and the operation also affects hormones involved in hunger and blood sugar control. The part of the stomach removed cannot be restored, so the operation is permanent. Long-term success depends on dietary changes, follow-up and lifelong nutritional care.

Eligibility depends on body mass index, obesity-related health conditions, previous weight-management attempts and overall surgical risk. Recent international guidelines from ASMBS and IFSO recommend considering metabolic and bariatric surgery for people with a BMI of 35 or more, and considering it for some people with a BMI of 30–34.9 who have metabolic disease. Different countries and hospitals may use different criteria, and thresholds can be lower for some Asian populations. A bariatric team should assess your medical history, eating patterns, mental health and readiness for long-term lifestyle changes.

Weight loss after a gastric sleeve varies widely and cannot be guaranteed. Many patients lose a substantial amount of weight during the first one to two years, but the result depends on starting weight, health conditions, eating habits, physical activity, medication, follow-up and individual metabolism. Weight regain can occur over time, especially if old eating patterns return. Improvement in conditions such as type 2 diabetes, high blood pressure or sleep apnoea may occur in some patients. Ask your bariatric team to explain realistic expectations for you.

Neither operation is best for everyone. A gastric sleeve removes part of the stomach without rerouting the intestine, while a gastric bypass creates a small stomach pouch and bypasses part of the intestine. A bypass may be preferred for some patients with severe acid reflux or certain metabolic conditions, while a sleeve may suit others because it is technically simpler and avoids intestinal rerouting. A sleeve can cause or worsen reflux in some patients. Both operations require lifelong nutritional follow-up. The choice should be made with a bariatric team after full assessment.

Gastric sleeve risks include bleeding, infection, blood clots and a leak from the staple line, which is a serious complication requiring urgent treatment. Other risks include narrowing of the sleeve, nausea, dehydration, new or worsening acid reflux, gallstones during rapid weight loss, nutritional deficiencies and weight regain. Long-term reflux may need investigation, and some teams recommend endoscopic surveillance. Warning signs such as fever, rapid heartbeat, worsening abdominal pain, shortness of breath or inability to keep fluids down need immediate medical attention.

After gastric sleeve surgery, patients usually follow a staged diet that moves gradually from clear liquids to full liquids, pureed foods, soft foods and then regular textures over several weeks. Protein is prioritised to support healing and preserve muscle. Portions are small, meals are eaten slowly, and many teams advise separating drinking from eating. Sugary drinks, fizzy drinks and high-calorie foods may cause problems or reduce weight loss. Lifelong vitamin and mineral supplements are commonly required. Follow the exact plan from your bariatric team and dietitian.

Assessment before gastric sleeve surgery usually includes a medical history, blood tests, review of medications and health conditions, and evaluation of surgical and anaesthesia risk. Depending on the hospital and your health, tests may include imaging, endoscopy, heart or lung assessment and a review of reflux symptoms. Nutrition and psychological assessment are important parts of bariatric care. Some teams prescribe a pre-operative diet to reduce liver size. If you are travelling, send full medical records in advance and ask which specialists form the bariatric team.

Patients are commonly advised to plan around 7–10 days in Turkey after gastric sleeve surgery, including a hospital stay of about one to three nights. This allows monitoring for early complications, checks that you can drink enough fluids, and advice on diet, medication and vitamins before flying. Long flights increase clot risk, so follow instructions on walking, hydration, compression and any anticoagulant medication. Before leaving, get your operation notes and a written plan for urgent symptoms. Our guide to complications after returning home explains what to watch for.

Gastric sleeve surgery requires long-term follow-up, not only a short post-operative check. Patients commonly need regular reviews with a doctor or bariatric team, dietitian advice, blood tests for nutritional deficiencies and lifelong supplements such as vitamin B12, iron, calcium and vitamin D, depending on local guidance. Arrange local medical support before surgery, especially if the operating hospital is abroad. Rapid weight loss can also leave loose skin, which some patients later address with plastic surgery once weight is stable. Read about body lift after weight loss.

Gastric sleeve cost in Turkey depends on the hospital, surgeon's fee, anaesthesia, surgical equipment, pre-operative tests, endoscopy or imaging, hospital nights, medication, dietitian support and follow-up. Some packages include accommodation, transfers and vitamins, while others do not. Ask how complications, readmission, additional procedures or extended hospital stays would be charged. Consider the cost of lifelong supplements and follow-up at home as well. Compare itemised quotes rather than package headlines. See our gastric sleeve cost page for recorded ranges.
