Treatment Overview
Sleeve Gastrectomy for Obesity is a widely performed bariatric surgery aimed at significant weight reduction in patients with moderate to severe obesity. The procedure involves removing a large portion of the stomach and forming a narrow, tube-shaped “sleeve,” which limits food intake and promotes early satiety. Additionally, it triggers hormonal changes that reduce appetite and improve metabolic health.
In Korea, this surgery is offered at leading bariatric centers using minimally invasive laparoscopic or robotic-assisted techniques. The country has become a top destination for medical tourists seeking effective obesity management due to its highly skilled surgeons, advanced technology, and comprehensive pre- and post-operative care.
Purpose & Benefits
The main purpose of sleeve gastrectomy for obesity is to achieve sustainable weight loss and reduce obesity-related health risks.
Key benefits include:
- Significant and sustained weight loss
- Improvement or resolution of obesity-related conditions such as type 2 diabetes, hypertension, sleep apnea, and fatty liver disease
- Reduced hunger and enhanced satiety due to 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 other obesity-related diseases
Ideal Candidates
This procedure is ideal 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 motivated to follow lifestyle modifications
- Seek a minimally invasive and highly effective obesity treatment
International patients benefit from Korea’s high-quality care, experienced surgeons, 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 ensure precision, reduced post-operative pain, and faster recovery.
Pre-operative evaluation includes lab tests, imaging, and nutritional counseling. Post-operative care involves diet progression, vitamin and mineral supplementation, and close monitoring to optimize weight loss and overall health outcomes.
Treatment Process in Korea
- Consultation & Assessment: Review of medical history, BMI, and evaluation of obesity-related conditions.
- Pre-Operative Preparation: Nutritional guidance, lab tests, and lifestyle counseling.
- Surgery: Laparoscopic or robotic-assisted sleeve gastrectomy, typically lasting 1–2 hours.
- Hospital Stay: Usually 2–4 days for monitoring, pain management, and early mobilization.
- Postoperative Care: Gradual diet progression, regular follow-up, and lifestyle counseling for sustainable weight loss and improved health.
International patients are supported by coordinators for travel, hospital admission, and post-operative follow-up.
Recovery & After-Care
Recovery generally involves:
- Mild pain or discomfort managed with medications
- Gradual return to normal activities within 1–2 weeks
- Strict adherence to post-operative dietary guidelines and supplementation
- Regular follow-up to monitor weight loss, nutritional status, and overall health
Patients are encouraged to maintain physical activity and lifestyle changes for optimal 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, adherence to post-operative care, and lifestyle modifications.
