→ Treatment Overview
Mini Gastric Bypass (MGB) for BMI ≥35 in Korea is a minimally invasive bariatric surgery designed for patients with severe obesity. The procedure involves creating a narrow gastric pouch and connecting it directly to a loop of the small intestine, which restricts food intake and reduces nutrient absorption.
Korean bariatric centers utilize advanced laparoscopic techniques to ensure precise surgery, faster recovery, and reduced risk of complications, making it ideal for international patients with BMI ≥35 seeking effective weight-loss solutions.
→ Purpose & Benefits
The primary goal is to achieve substantial weight loss and improve obesity-related metabolic health.
Key benefits include:
→ Significant and rapid weight loss for patients with severe obesity
→ Improvement or remission of obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea
→ Minimally invasive procedure with faster recovery
→ Reduced surgical complications compared to traditional gastric bypass in select patients
→ Enhanced quality of life and long-term health benefits
MGB addresses both weight management and metabolic improvement for high-BMI patients.
→ Ideal Candidates
This surgery is ideal for patients with BMI ≥35 seeking effective and long-term weight loss.
Ideal candidates include:
→ Adults with BMI ≥35 or BMI ≥30 with comorbidities
→ Patients with obesity-related metabolic conditions like diabetes or hypertension
→ Individuals who have not achieved success with diet, exercise, or medications
→ Those committed to follow-up care, dietary changes, and lifestyle modification
→ International patients seeking advanced bariatric surgery in Korea
Comprehensive pre-operative assessment ensures safety and personalized care.
→ Possible Risks & Complications
While generally safe, MGB carries potential risks.
Possible risks include:
→ Leakage or bleeding at the surgical site
→ Nutritional deficiencies if post-operative diet and supplementation are not followed
→ Gastroesophageal reflux or marginal ulcers
→ Bowel obstruction or internal hernia (rare)
→ Dumping syndrome causing nausea or diarrhea after high-sugar meals
Korean clinics provide structured follow-up to manage complications promptly.
→ Techniques & Technology Used
Korean centers utilize state-of-the-art laparoscopic and surgical technologies for MGB.
Common techniques include:
→ High-definition laparoscopic imaging for accurate pouch creation
→ Single or multiple anastomosis techniques connecting the pouch to the small intestine
→ Intraoperative imaging to ensure precision and safety
→ Post-operative digital monitoring of weight, nutrition, and metabolic markers
→ Multidisciplinary care involving dietitians and endocrinologists
Advanced technology ensures precise, safe, and effective surgery.
→ Treatment Process in Korea
The MGB process is structured for optimal surgical and post-op outcomes.
Typical process includes:
→ Pre-operative evaluation: labs, imaging, nutritional and psychological assessment
→ Laparoscopic mini gastric bypass under general anesthesia
→ Hospital stay for 2–3 days with monitoring
→ Post-operative follow-up including dietary guidance, metabolic monitoring, and lifestyle coaching
→ Long-term support for exercise, diet, and metabolic health
International patient coordinators assist with travel, appointments, and language support.
→ Recovery & After-Care
Recovery focuses on healing, nutrition, and lifestyle adaptation.
After-care includes:
→ Gradual diet progression from liquids to solids under dietitian supervision
→ Nutritional supplementation to prevent deficiencies
→ Monitoring for post-operative complications
→ Regular follow-up to track weight loss and metabolic improvement
→ Lifestyle coaching including exercise and behavioral guidance
Structured after-care ensures safe recovery and lasting results.
→ Results & Longevity
Patients generally achieve substantial, long-term weight loss and metabolic improvement.
Expected outcomes include:
→ Loss of 60–80% of excess body weight within 1–2 years
→ Improvement or remission of type 2 diabetes, hypertension, and other obesity-related conditions
→ Long-term maintenance of weight loss with adherence to diet and lifestyle modifications
→ Enhanced quality of life and reduced obesity-related health risks
Consistent follow-up and support maximize longevity of results.
