Treatment Overview
Vertical Sleeve Gastrectomy (VSG) is a minimally invasive bariatric surgery designed to help patients achieve long-term weight loss and improve obesity-related health conditions. The procedure involves removing approximately 75–80% of the stomach, creating a narrow, tube-shaped “sleeve” that limits food intake and reduces hunger by decreasing ghrelin hormone production.
In Korea, VSG is performed at specialized bariatric and digestive surgery centers using advanced laparoscopic or robotic-assisted techniques. It is suitable for patients with obesity, especially those with comorbidities such as type 2 diabetes, hypertension, or sleep apnea. Korean clinics combine skilled surgeons, cutting-edge technology, and comprehensive pre- and post-operative care to deliver high-quality outcomes for both local and international patients.
Purpose & Benefits
The main purpose of vertical sleeve gastrectomy is to facilitate significant and sustainable weight loss while improving metabolic and obesity-related conditions.
Key benefits include:
- Effective long-term weight reduction
- Improvement or resolution of type 2 diabetes, hypertension, and sleep apnea
- Reduced hunger and enhanced satiety
- Minimally invasive surgery with smaller incisions and less pain
- Shorter recovery time compared to traditional surgery
- Improved mobility, energy levels, and overall quality of life
Ideal Candidates
Vertical sleeve gastrectomy is suitable for patients who:
- Have a Body Mass Index (BMI) ≥ 35, or ≥ 30 with obesity-related conditions
- Have been unable to achieve sufficient weight loss through diet, exercise, or medications
- Are physically fit for surgery and willing to adhere to lifestyle changes
- Are motivated to maintain long-term dietary and behavioral modifications
International patients seeking effective bariatric solutions benefit from Korea’s advanced surgical standards and comprehensive medical tourism services.
Possible Risks & Complications
While VSG is generally safe, potential risks include:
- Bleeding or infection
- Staple line leaks
- Nutritional deficiencies if post-operative dietary guidelines are not followed
- Gastroesophageal reflux or stomach irritation
- Rare complications such as blood clots or adverse anesthesia reactions
Korean clinics conduct detailed pre-operative assessments and provide nutritional counseling to minimize risks and ensure patient safety.
Techniques & Technology Used
Korean hospitals utilize advanced laparoscopic and robotic-assisted techniques for vertical sleeve gastrectomy. These approaches ensure smaller incisions, less post-operative pain, and faster recovery.
Pre-operative preparation includes imaging, laboratory tests, and nutritional counseling. Postoperative care involves diet progression, lab monitoring, and lifestyle guidance to optimize weight loss and metabolic improvements.
Treatment Process in Korea
- Consultation & Assessment: Review of medical history, BMI evaluation, and pre-operative testing.
- Pre-Operative Preparation: Nutritional counseling, lab tests, and lifestyle instructions.
- Surgery: Laparoscopic or robotic-assisted removal of the majority of the stomach to form a sleeve. The procedure generally takes 1–2 hours.
- Hospital Stay: Typically 2–4 days for monitoring, pain management, and early mobilization.
- Postoperative Care: Gradual diet progression from liquids to solids, follow-up appointments, and lifestyle counseling.
International patients are supported by coordinators who assist with hospital admission, travel, and post-operative follow-up.
Recovery & After-Care
Recovery includes:
- Mild post-operative pain managed with medications
- Gradual return to daily activities within 1–2 weeks
- Strict adherence to post-surgery dietary guidelines and portion control
- Regular follow-up to monitor weight loss, nutritional status, and health improvements
Patients are encouraged to incorporate physical activity gradually and maintain long-term lifestyle changes for optimal 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 health benefits if lifestyle changes are sustained
Results may vary based on adherence to post-operative care, diet, and exercise routines.
