Gastric sleeve surgery is an effective bariatric procedure that reduces the size of the stomach in suitable patients, helping them feel full with smaller portions. Obesity can lead to numerous health problems, including diabetes, hypertension, sleep apnea, fatty liver disease, joint pain, and a reduced quality of life.

What Is Gastric Sleeve Surgery?

Gastric sleeve surgery, medically known as sleeve gastrectomy, is a procedure in which a large portion of the stomach is surgically removed, leaving behind a narrower, banana-shaped stomach tube. The procedure reduces the stomach’s capacity, allowing patients to feel full after eating smaller portions. It may also produce hormonal changes that influence appetite.

Gastric sleeve surgery is not a bypass procedure in which the route of the intestines is altered. Food continues to pass through the natural digestive pathway. However, because the stomach’s capacity is significantly reduced, the patient’s eating habits must change completely after surgery.

Why Is Gastric Sleeve Surgery in Turkey Frequently Preferred?

Turkey is one of the countries frequently chosen for bariatric surgery within the field of medical tourism. The main reasons include experienced surgical teams, modern hospital infrastructure, international patient coordination, convenient transportation, and the ability to organise postoperative follow-up through multidisciplinary teams.

For international patients, the process involves more than the operation itself. Preoperative assessment, diagnostic testing, hospital arrangements, accommodation support, interpreter services, nutritional education, and remote postoperative follow-up are also important.

Healthylife Clinic manages this process with a patient-centred approach, providing VIP transportation, accommodation in five-star hotels, and treatment or surgery in advanced A+ hospitals equipped with high-level medical technology. Patients are discharged safely after their treatment and postoperative evaluation have been completed.

Who Is Gastric Sleeve Surgery Suitable For?

Gastric sleeve surgery is not suitable for everyone who has difficulty managing their weight. Patient selection must be based on medical criteria. Body mass index, obesity-related conditions, previous weight-loss attempts, psychological readiness, and the patient’s ability to adapt to postoperative lifestyle changes must all be evaluated.

Gastric sleeve surgery may generally be considered for:

• Patients with a high body mass index

• Individuals who have been unable to achieve long-term weight loss through diet and exercise

• Patients with associated conditions such as type 2 diabetes, hypertension, or sleep apnea

• Individuals experiencing joint problems or restricted mobility due to obesity

• Patients who are able to follow postoperative dietary guidelines

• Individuals who accept the need for regular follow-up

• Patients considered medically suitable for general anaesthesia and surgery

How Is Gastric Sleeve Surgery Performed?

Gastric sleeve surgery is generally performed using a minimally invasive laparoscopic technique. Small incisions are made in the abdomen, and the stomach is reshaped with the assistance of a camera and specialised advanced surgical instruments. A large portion of the stomach is removed, and the remaining section is formed into a narrow tube.

The operation is performed under general anaesthesia. The stomach’s capacity is reduced, but the intestinal absorption pathway is not altered. After surgery, the patient is closely monitored for fluid intake, pain control, early mobilisation, and signs of complications such as leakage or bleeding.

How Much Weight Can Be Lost After Gastric Sleeve Surgery?

Patients may lose approximately 20 to 40 kilograms after gastric sleeve surgery. However, the amount of weight loss varies from person to person. Starting weight, age, metabolism, adherence to dietary recommendations, physical activity, hormonal factors, and the quality of postoperative follow-up can all affect the outcome.

For this reason, it is not medically appropriate to claim that every patient will lose a specific amount of weight.

What Are the Risks of Gastric Sleeve Surgery?

Although gastric sleeve surgery is an effective bariatric procedure, it is still a major surgical operation. Early risks may include bleeding, infection, complications related to anaesthesia, blood clots, respiratory problems, and leakage from the gastric staple line.

Long-term complications may include acid reflux, nutritional deficiencies, vitamin and mineral deficiencies, and weight regain.

With a professional medical team and physicians who have more than 25 years of clinical experience, Healthylife Clinic performs the procedure with meticulous attention to surgical safety, hygiene, and sterile operating conditions.

The decision to undergo surgery should never be based solely on the patient’s weight. An experienced surgical team, appropriate hospital conditions, careful patient selection, and regular follow-up are fundamental to a safe treatment process.

What Is the Diet Like After Gastric Sleeve Surgery?

Nutrition after gastric sleeve surgery progresses in stages. Patients initially begin with a liquid diet, followed by puréed foods, soft foods, and eventually solid foods.

Eating too quickly, taking large bites, consuming carbonated beverages, or failing to obtain sufficient protein may cause problems during recovery.

The nutrition programme should be personalised for each patient. Adequate protein intake, sufficient hydration, vitamin and mineral supplementation, and regular medical check-ups are important for healthy and sustainable weight loss.

The operation only reduces the size of the stomach. Long-term success depends on the patient’s ability to maintain a new and healthier lifestyle.

How Long Should International Patients Stay in Turkey After Gastric Sleeve Surgery?

An average stay of approximately six days is generally sufficient. However, for patients travelling to Turkey for medical tourism, the total length of stay is determined according to the preoperative tests, the operation, hospitalisation, and the timing of the first postoperative check-up.

Return travel should not be arranged until the patient’s general health, recovery progress, and fitness to fly have been medically evaluated.

International patients should receive clear guidance regarding postoperative nutrition, medication use, wound care, warning signs that require urgent medical attention, and remote follow-up.

This allows the treatment process to continue in a controlled manner after the patient returns to their home country.

Can Weight Be Regained After Gastric Sleeve Surgery?

Gastric sleeve surgery provides a strong starting point for weight loss. However, permanent success requires long-term lifestyle changes.

Over time, the stomach’s capacity may increase slightly. Weight regain may also occur if the patient begins consuming high-calorie liquids, snacks frequently, or returns to irregular eating habits.

For this reason, regular follow-up, nutritional counselling, an appropriate exercise programme, and psychological support should be included in the treatment process whenever necessary.

Bariatric surgery is not simply a one-day operation. It is a long-term health programme that requires continued commitment.
