Treatment Overview
Roux‑en‑Y Gastric Bypass (RYGB) is one of the most commonly performed bariatric surgeries worldwide, designed to treat severe obesity and obesity-related metabolic disorders. The procedure involves creating a small stomach pouch and rerouting a portion of the small intestine, limiting food intake and altering gut hormones to improve metabolism. In Korea, RYGB is performed using advanced laparoscopic or robotic-assisted techniques, ensuring precision, safety, and faster recovery for international patients.
Purpose & Benefits
Roux‑en‑Y Gastric Bypass offers multiple benefits:
- Significant and sustained weight loss.
- Improvement or remission of type 2 diabetes and insulin resistance.
- Reduction in hypertension, dyslipidemia, and other obesity-related conditions.
- Enhanced energy levels, metabolism, and overall well-being.
- Long-term improvement in quality of life and eating habits.
Ideal Candidates
RYGB is recommended for:
- Adults with BMI ≥ 35.
- Patients with BMI 30–34.9 who have obesity-related comorbidities.
- Individuals with type 2 diabetes or metabolic syndrome seeking surgical intervention.
- Adults aged 18–65 committed to lifestyle changes, dietary adherence, and regular follow-ups.
Possible Risks & Complications
Potential risks include:
- Surgical complications such as bleeding, infection, or reactions to anesthesia.
- Nutritional deficiencies (vitamins B12, D, calcium, iron).
- Dumping syndrome or digestive issues.
- Rare complications such as leaks at the surgical site, bowel obstruction, or ulcers.
Korean hospitals minimize risks with thorough pre-operative assessments, minimally invasive techniques, and structured post-operative care.
Techniques & Technology Used
Korean hospitals employ advanced technology for optimal outcomes:
- Laparoscopic RYGB: Minimally invasive approach for faster recovery and smaller scars.
- Robotic-Assisted Surgery (optional): Enhances precision in complex cases.
- High-Definition Imaging & Navigation: Ensures accurate pouch creation and intestinal rerouting.
- Post-Operative Monitoring Systems: Tracks weight loss, nutritional intake, and metabolic health.
- Multidisciplinary Care: Surgeons, dietitians, endocrinologists, and psychologists collaborate for holistic patient support.
Treatment Process in Korea
- Consultation: Review of medical history, BMI, metabolic health, and comorbidities.
- Pre-Operative Testing: Blood tests, imaging studies, nutritional and hormonal evaluations.
- Surgery: Performed under general anesthesia, typically lasting 2–4 hours.
- Hospital Stay: 2–4 days with multidisciplinary monitoring.
- Post-Operative Care: Includes dietary guidance, exercise planning, metabolic monitoring, and regular follow-ups.
Recovery & After-Care
- Immediate Post-Surgery: Light walking, hydration, and liquid diet.
- Weeks 2–4: Gradual transition from liquid to soft foods, then solid foods under dietitian supervision.
- Nutritional Supplements: Essential vitamins and minerals to prevent deficiencies.
- Lifestyle Guidance: Balanced diet, portion control, exercise, and behavioral counseling.
- Regular Follow-Ups: Ensure proper weight loss, metabolic improvement, and nutritional balance.
Results & Longevity
- Patients typically achieve 60–80% excess weight loss within 12–18 months.
- Significant improvement or remission of type 2 diabetes, hypertension, and dyslipidemia.
- Lifelong adherence to diet, supplements, and follow-ups ensures sustained outcomes.
- High patient satisfaction due to comprehensive, multidisciplinary care and effective results.
