Treatment Overview
Laparoscopic Sleeve Gastrectomy is a minimally invasive bariatric surgery designed to help patients achieve significant and sustained weight loss. The procedure involves removing approximately 75–80% of the stomach, creating a narrow “sleeve” that restricts food intake and reduces hunger by lowering ghrelin hormone levels.
In Korea, this surgery is performed at leading bariatric and digestive surgery centers using advanced laparoscopic techniques. It is highly recommended for patients with obesity, especially those with associated health conditions such as type 2 diabetes, hypertension, or sleep apnea. Korean clinics combine state-of-the-art surgical technology, experienced surgeons, and comprehensive pre- and post-operative care to deliver optimal results for both domestic and international patients.
Purpose & Benefits
The primary purpose of laparoscopic sleeve gastrectomy is to promote weight loss and improve obesity-related health issues.
Key benefits include:
- Significant and sustainable weight reduction
- Improvement or resolution of type 2 diabetes, hypertension, and sleep apnea
- Reduced hunger and better satiety control
- Minimally invasive procedure with small incisions
- Shorter recovery time and less post-operative discomfort
- Enhanced mobility, self-esteem, and overall quality of life
Ideal Candidates
Laparoscopic sleeve gastrectomy is suitable for patients who:
- Have a Body Mass Index (BMI) ≥ 35, or ≥ 30 with obesity-related conditions
- Have been unsuccessful with conventional weight loss methods such as diet, exercise, or medications
- Are physically fit for surgery and willing to follow lifestyle modifications
- Are motivated to commit to long-term dietary and behavioral changes
International patients seeking a safe and effective bariatric solution can benefit from Korea’s high medical standards and specialized surgical care.
Possible Risks & Complications
Although the procedure is generally safe, potential risks include:
- Bleeding or infection
- Leakage from the staple line
- Nutritional deficiencies if dietary guidelines are not followed
- Gastroesophageal reflux or stomach irritation
- Rare complications such as blood clots or adverse reactions to anesthesia
Korean clinics provide thorough pre-operative assessments, nutritional counseling, and detailed post-operative care to minimize risks and ensure safety.
Techniques & Technology Used
Korean clinics utilize advanced laparoscopic techniques for sleeve gastrectomy, ensuring smaller incisions, reduced post-operative pain, and faster recovery. Some centers offer robotic-assisted surgery for greater precision.
Pre-operative imaging, lab tests, and nutritional assessments are standard. Post-operative follow-up includes diet progression, lab tests, and monitoring for complications, ensuring comprehensive care.
Treatment Process in Korea
- Consultation & Assessment: Medical history review, BMI evaluation, and pre-operative testing.
- Pre-Operative Preparation: Nutritional guidance, lab tests, and lifestyle instructions.
- Surgery: Laparoscopic removal of the majority of the stomach, creating a sleeve. Procedure usually lasts 1–2 hours.
- Hospital Stay: Typically 2–4 days for recovery and monitoring.
- Postoperative Care: Gradual diet progression from liquids to solids, follow-up appointments, and lifestyle counseling.
International patients are supported by coordinators who assist with travel, hospital admission, and follow-up care.
Recovery & After-Care
Recovery generally involves:
- Mild post-operative pain managed with medication
- Gradual return to daily activities within 1–2 weeks
- Strict adherence to post-surgery dietary and lifestyle guidelines
- 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 to optimize results.
Results & Longevity
Patients typically experience:
- 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 quality of life
- Long-term health benefits if lifestyle changes are sustained
Results depend on adherence to post-operative care, diet, and exercise routines.
