Sleeve gastrectomy is one of the most widely performed bariatric procedures worldwide, carried out at The Specialty Hospital under high safety standards and the supervision of a specialized surgical team. The procedure involves the removal of approximately 80% of the stomach along the greater curvature, creating a tubular, sleeve-shaped stomach — roughly the size and shape of a banana — that preserves core digestive functions while significantly limiting food intake. The procedure is performed laparoscopically, is considered permanent and irreversible, although mild dilation of the stomach may occur over time.
Surgical Mechanism:
Sleeve gastrectomy is classified as a restrictive procedure, as it reduces the stomach's food-holding capacity. The surgery is performed through small abdominal incisions through which precise surgical instruments are introduced. A laparoscopic camera provides continuous, clear visualization of the abdominal cavity throughout the procedure, ensuring accurate resection and reliable surgical outcomes.
Indications — Based on Updated ASMBS/IFSO 2022 Guidelines:
The previously established criteria have been replaced by updated, evidence-based guidelines issued by the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO). Current indications include:
Prior to surgery, all patients undergo a comprehensive multidisciplinary evaluation — including surgical, nutritional, psychological, and medical assessments — to confirm candidacy and ensure medical suitability for the procedure
What to Expect After Surgery?
Most patients are hospitalized for 1 to 2 days and resume normal physical activities within 4 to 6 weeks. Standard postoperative care includes:
Regular follow-up with the nutrition team to assess protein and micronutrient levels, with prescribed vitamin and mineral supplementation to prevent deficiencies and malnutrition
Expected Weight Loss Outcomes
Evidence from multicenter studies and 2024–2025 systematic reviews indicates an average excess weight loss (EWL) of 55–65% over a follow-up period of 5 to 10 years. Outcomes are influenced by several factors, including:
Comprehensive Care at The Specialty Hospital
The Specialty Hospital provides an integrated, multidisciplinary approach before, during, and after surgery — encompassing bariatric surgeons, internal medicine physicians, clinical dietitians, and psychological support Long-term follow-up, nutritional supplementation, and behavioral modification are considered fundamental pillars in achieving sustained weight loss and improved quality of life
