Treatment Overview
Sleeve Gastrectomy for BMI ≥35 in Korea is a bariatric surgery specifically designed for patients with severe obesity. The procedure reduces the stomach to a narrow, sleeve-like shape, restricting food intake and promoting early satiety. Hormonal changes after surgery also help regulate appetite and improve metabolism, making it an effective solution for long-term weight management.
Korean hospitals perform this surgery using advanced laparoscopic or robotic-assisted techniques, ensuring safety, precision, and faster recovery. The procedure is complemented by a comprehensive care program, including pre-operative assessment, nutritional counseling, and structured post-operative follow-up, ideal for both domestic and international patients.
Purpose & Benefits
The main purpose of this procedure is to provide substantial and sustainable weight loss while reducing obesity-related health risks.
Key benefits include:
- Significant weight reduction for patients with BMI ≥35
- Improvement in obesity-related comorbidities such as type 2 diabetes, hypertension, and dyslipidemia
- Hormonal changes promoting satiety and reduced appetite
- Minimally invasive surgery with smaller incisions and faster recovery
- Enhanced energy, mobility, and overall quality of life
- Long-term improvement in metabolic and cardiovascular health
- High success rates for sustained weight management when combined with lifestyle changes
Ideal Candidates
This surgery is suitable for patients who:
- Have a Body Mass Index (BMI) of 35 or higher
- Have not achieved adequate weight loss through diet, exercise, or medical therapy
- Are medically fit for surgery and committed to post-operative dietary and lifestyle changes
- Seek a safe and effective method for long-term weight management
Korean hospitals provide a multidisciplinary team approach, including bariatric surgeons, dietitians, and endocrinologists, to ensure optimal outcomes.
Possible Risks & Complications

- Rare complications such as blood clots or anesthesia-related events
Korean hospitals ensure meticulous pre-operative assessment and structured post-operative care to minimize these risks.
Techniques & Technology Used
Korean hospitals use state-of-the-art laparoscopic and robotic-assisted techniques for sleeve gastrectomy, featuring:
- High-definition laparoscopic cameras for precise visualization
- Advanced stapling devices for safe stomach reshaping
- Pre- and post-operative nutritional assessment and monitoring
- Multidisciplinary support including surgeons, dietitians, and endocrinologists
