Gastric Sleeve Surgery in Istanbul, Turkey by Avicenna Hospital

Advanced Bariatric Surgery for Sustainable Weight Loss, Improved Health & Long-Term Lifestyle Transformation



Gastric Sleeve Surgery, also known as Sleeve Gastrectomy, is one of the most effective and widely performed weight loss procedures for patients struggling with obesity and related health conditions. At Avicenna Hospital in Istanbul, this procedure is performed using advanced laparoscopic techniques, focusing on safety, precision, and long-term success. Patients choose gastric sleeve surgery not only for significant weight reduction but also for improvement in metabolic health, mobility, and overall quality of life. With a structured treatment approach and ongoing medical support, this procedure helps patients achieve lasting transformation while maintaining a natural digestive process.



🩺 What Is Gastric Sleeve Surgery?

Gastric Sleeve Surgery is a minimally invasive bariatric procedure that reduces the size of the stomach by approximately 70–80%, creating a narrow, tube-like “sleeve.” This significantly limits food intake and helps patients feel full much faster, supporting controlled eating habits and consistent weight loss. During the procedure, a large portion of the stomach is removed laparoscopically through small incisions.

The remaining stomach is reshaped into a slim structure while preserving its natural function within the digestive system. Unlike some other bariatric procedures, gastric sleeve surgery does not involve rerouting the intestines, making it a simpler and widely preferred option.

In addition to restricting food intake, the surgery also impacts hunger-regulating hormones, particularly ghrelin, leading to reduced appetite and fewer cravings. This dual effect makes gastric sleeve surgery highly effective for patients who have struggled with traditional weight loss methods.

Patients often experience significant improvements in obesity-related conditions such as type 2 diabetes, high blood pressure, sleep apnea, and joint pain. With proper follow-up and lifestyle adjustments, the results are long-lasting and contribute to overall health improvement and increased life expectancy.



🩺 Types of Gastric Sleeve Procedures

Sleeve Gastrectomy (Standard Laparoscopic) – The most common approach performed using minimally invasive techniques with small incisions and faster recovery.

Single Incision Gastric Sleeve – Performed through a single entry point for reduced scarring and enhanced cosmetic outcomes.

Robotic-Assisted Gastric Sleeve – Utilizes advanced robotic systems for increased precision and control during surgery.

Revisional Gastric Sleeve – Performed for patients who previously underwent bariatric surgery and require further correction or optimization.



🩺 Who Is a Good Candidate?
