Treatment Overview
Sleeve Gastrectomy for BMI ≥35 is a bariatric surgery specifically designed for patients with severe obesity. The procedure involves removing a large portion of the stomach to create a narrow, tube-shaped “sleeve,” which restricts food intake and promotes early satiety. Additionally, it triggers hormonal changes that reduce appetite and enhance metabolic health.
In Korea, this surgery is performed at top bariatric centers using minimally invasive laparoscopic or robotic-assisted techniques. The combination of experienced surgeons, state-of-the-art technology, and comprehensive pre- and post-operative care makes Korea a preferred destination for both domestic and international patients seeking safe and effective weight loss solutions.
Purpose & Benefits
The main purpose of sleeve gastrectomy for BMI ≥35 is to achieve significant and sustained weight loss while reducing obesity-related health risks.
Key benefits include:
- Significant and sustained reduction of excess body weight
- Improvement or resolution of obesity-related conditions such as type 2 diabetes, hypertension, sleep apnea, and fatty liver disease
- Reduced hunger and enhanced satiety through hormonal changes
- Minimally invasive surgery with smaller incisions and faster recovery
- Long-term improvement in quality of life, mobility, and energy levels
- Reduced risk of cardiovascular complications and metabolic disorders
Ideal Candidates
This procedure is suitable for patients who:
- Have a Body Mass Index (BMI) ≥ 35, or ≥ 30 with obesity-related comorbidities
- Have been unable to achieve sufficient weight loss through diet, exercise, or medications
- Are physically fit for surgery and committed to post-operative lifestyle changes
- Seek a minimally invasive, effective, and safe bariatric procedure
International patients benefit from Korea’s high standards of surgical expertise, advanced facilities, and medical tourism support services.
Possible Risks & Complications
While generally safe, potential risks include:
- Bleeding or infection
- Staple line leaks
- Nutritional deficiencies if post-operative diet is not followed
- Gastroesophageal reflux or stomach irritation
- Rare complications such as blood clots or anesthesia-related issues
Korean hospitals conduct detailed pre-operative assessments, imaging, and nutritional counseling to minimize risks and ensure patient safety.
Techniques & Technology Used
Korean bariatric centers use advanced laparoscopic and robotic-assisted techniques for sleeve gastrectomy. These minimally invasive methods provide precision, less post-operative pain, and faster recovery.
Pre-operative preparation includes lab tests, imaging, and dietary assessment. Post-operative care involves gradual diet progression, vitamin and mineral supplementation, and monitoring to optimize weight loss and metabolic health.
Treatment Process in Korea
- Consultation & Assessment: Review of medical history, BMI, and obesity-related conditions.
- Pre-Operative Preparation: Nutritional counseling, lab tests, and lifestyle guidance.
- Surgery: Laparoscopic or robotic-assisted sleeve gastrectomy, usually lasting 1–2 hours.
- Hospital Stay: Typically 2–4 days for monitoring, pain management, and early mobilization.
- Postoperative Care: Gradual diet progression, regular follow-up, and lifestyle counseling to ensure sustained weight loss and health improvements.
International patients are assisted with travel, hospital admission, and post-operative care.
Recovery & After-Care
Recovery generally involves:
- Mild post-operative discomfort managed with medication
- Gradual return to normal activities within 1–2 weeks
- Adherence to dietary guidelines and supplementation
- Regular follow-up to monitor weight, nutritional status, and overall health
Patients are encouraged to maintain physical activity and lifestyle changes for long-term results.
Results & Longevity
Patients can expect:
- Significant weight loss of 50–70% of excess body weight within 12–18 months
- Improvement or resolution of obesity-related conditions
- Enhanced energy, mobility, and overall quality of life
- Long-term benefits if dietary and lifestyle recommendations are followed
Results may vary depending on individual health and adherence to post-operative care.
