Obesity Surgery Methods Performed in Turkey

1. Sleeve Gastrectomy

Sleeve gastrectomy is the most commonly performed obesity surgery in Turkey. In this method, about 80% of the stomach is surgically removed, leaving a narrow, banana-shaped tube. This significantly reduces stomach capacity and lowers the production of ghrelin, the hormone responsible for hunger. As a result, patients feel full with smaller amounts of food and naturally reduce their calorie intake. The procedure is performed using minimally invasive laparoscopic or robotic techniques, which ensure smaller incisions, less pain, and faster recovery.

Weight loss after sleeve gastrectomy is usually significant, with most patients losing 60–70% of their excess weight within 12–18 months. Beyond weight reduction, many obesity-related health conditions such as type 2 diabetes, hypertension, and sleep apnea also improve or resolve after the surgery. Due to its high success rates and relatively low risk of complications, sleeve gastrectomy is considered the first-line surgical option for many international patients choosing Turkey for obesity treatment.

2. Roux-en-Y Gastric Bypass

Roux-en-Y gastric bypass is another highly effective bariatric surgery method. It involves creating a small gastric pouch from the upper part of the stomach and bypassing the first 75–150 cm of the small intestine. This dual mechanism both restricts food intake and reduces calorie absorption. The procedure is particularly successful in achieving long-term weight control and improving metabolic conditions.

Clinical studies show that gastric bypass offers high rates of diabetes remission and lower chances of weight regain compared to other methods. Turkish bariatric surgeons perform the operation laparoscopically, which reduces hospital stay and accelerates recovery. Patients typically experience substantial weight loss within the first year, alongside marked improvements in cholesterol, blood pressure, and overall quality of life.

3. Mini Gastric Bypass

Mini gastric bypass is a simplified version of the Roux-en-Y procedure and is performed through a single surgical connection (anastomosis). This technique shortens operative time, reduces surgical risks, and lowers complication rates. The procedure bypasses about 150–200 cm of the small intestine, resulting in both restrictive and malabsorptive effects.

Patients undergoing mini gastric bypass often achieve up to 70% loss of excess weight. Additionally, the shorter operating time makes it a safer option for patients with higher surgical risk. Turkish hospitals specializing in bariatric surgery frequently recommend this method for those seeking effective results with fewer operative steps.

4. Gastric Band

The gastric band procedure is one of the least invasive obesity surgery methods. A silicone band is placed around the upper portion of the stomach, creating a small pouch that limits the amount of food passing into the lower stomach. The band can be adjusted through a subcutaneous port, enabling gradual changes in restriction according to patient needs.

Although it is a less invasive procedure, gastric band surgery requires close and regular follow-up. Adjustments to the band must be made periodically, and patient compliance with dietary and lifestyle recommendations is essential. While the weight loss may be slower compared to other surgeries, it remains a valuable option for patients who prefer a reversible and adjustable approach.

5. Biliopancreatic Diversion with Duodenal Switch (BPD-DS)

BPD-DS is one of the most complex yet powerful bariatric surgery methods. It involves removing a large portion of the stomach and rerouting the intestines to create both restrictive and malabsorptive effects. This results in the highest rates of weight loss among all obesity surgeries, making it particularly effective for patients with severe obesity.

However, the procedure requires lifelong nutritional support. Patients must take daily vitamin and mineral supplements and undergo regular medical check-ups to prevent deficiencies. In Turkey, this operation is performed in specialized centers with experienced surgeons, ensuring safety and long-term follow-up.

6. Endoscopic Gastric Balloon & Plication (Endo-Sleeve)

Endoscopic methods such as gastric balloon and plication offer non-surgical alternatives for obesity management. In the gastric balloon procedure, a silicone balloon is placed into the stomach via endoscopy and inflated to reduce capacity, while plication involves endoscopic suturing to mimic the effect of a sleeve gastrectomy.

These methods are ideal for patients with a BMI between 30–35 who are not yet candidates for surgical intervention. They are temporary solutions, often used for short-term weight reduction or preparation before a larger operation. Turkish hospitals offer these procedures as minimally invasive, safe, and effective options, particularly for patients seeking a non-surgical path.

Post-Operative Services

The period after obesity surgery is as important as the surgery itself. In the first six months, nutritional supplements, high-protein liquid diets, and gradually increasing physical activity play a crucial role in recovery. Patients are closely guided through tailored diet plans that evolve from liquid to solid food stages, ensuring their body adapts smoothly to the new digestive system.

Follow-up programs often include regular health monitoring, consultations with dietitians, and psychological support to help patients adapt to lifestyle changes. Turkish hospitals emphasize this structured post-operative care to ensure both medical safety and sustained results.

Why Choose a JCI-Accredited Center for Treatment in Turkey?

JCI accreditation represents the highest global standard in healthcare quality and patient safety. Hospitals that hold this certificate undergo rigorous inspections every three years, covering more than 1,200 criteria including infection control, surgical safety, and medication management. For international patients, this means reliable treatment in sterile and controlled environments.

Additionally, JCI-accredited hospitals in Turkey provide transparent clinical outcomes, low complication rates, and internationally compatible medical records. These features reassure patients and their insurers, creating a smooth and trustworthy medical journey. Choosing such a center ensures that every step, from surgery to follow-up, is carried out with international excellence.

Obesity Surgery at Pendik Bölge Hospital

Bölge Hospital, located on Istanbul’s Asian side, is one of Turkey’s leading JCI-accredited hospitals. Having received accreditation for the fifth time, the hospital’s bariatric surgery unit combines advanced technology with patient-centered care. Upon arrival, VIP vehicles pick patients up from the airport, ensuring comfort from the first step.

The hospital offers luxury patient rooms, multilingual support, and a dedicated international patient office. After pre-operative evaluations, surgery usually takes 1–2 hours, followed by a 2–3 day hospital stay. Post-operative nutrition and exercise programs are arranged by a multidisciplinary team, and the hospital remains in close contact with patients for at least one year after discharge to ensure long-term success.

Obesity Surgery Prices in Turkey

The cost of obesity surgery in Turkey depends on several factors, including the chosen procedure, coexisting medical conditions, and the surgical technique used. Package options usually cover not only the operation itself but also hospital stay, accommodation, airport transfers, and post-operative follow-up services.

Compared with Western countries, fees are highly competitive while maintaining top-quality care. For international patients, this combination of affordability and excellence is highly attractive. To receive an accurate cost calculation tailored to individual needs, patients can contact international patient representatives who provide transparent and personalized quotations.
