Gastric Sleeve in Turkey: What International Patients Should Know
Planning Gastric Sleeve Surgery in Turkey? Learn about candidacy, the treatment process, recovery timeline, expected weight loss, and what is included in international patient packages.

What Is Gastric Sleeve Surgery?
Gastric sleeve surgery, also known as sleeve gastrectomy, is one of the most effective bariatric procedures for long-term weight loss. During the operation, approximately 75–80% of the stomach is removed, creating a smaller, tube-shaped stomach. This limits food intake and helps reduce hunger hormones, making it easier for patients to achieve sustainable weight loss and improve obesity-related health conditions.

Who Is a Candidate?
Gastric sleeve surgery may be suitable for adults with obesity who have struggled to lose weight through diet and exercise alone. It is commonly recommended for patients with a BMI over 40, or over 35 when obesity-related conditions such as type 2 diabetes, hypertension, or sleep apnea are present. Every patient should be evaluated individually by an experienced bariatric surgeon.
