Treatment Overview
Roux‑en‑Y Surgery is a type of gastric bypass procedure commonly performed to treat severe obesity and related metabolic disorders. The surgery involves creating a small stomach pouch and rerouting a section of the small intestine, which limits food intake and alters gut hormone responses to improve metabolism. In Korea, Roux‑en‑Y Surgery is performed using advanced laparoscopic or robotic-assisted techniques, combined with comprehensive pre- and post-operative care, ensuring optimal safety and effectiveness for international patients.
Purpose & Benefits
Roux‑en‑Y Surgery is designed to achieve:
- Significant and sustained weight loss.
- Improvement or remission of type 2 diabetes.
- Reduction in obesity-related conditions such as hypertension, dyslipidemia, and sleep apnea.
- Improved energy levels and metabolic health.
- Long-term lifestyle and dietary habit improvements.
Ideal Candidates
Roux‑en‑Y Surgery is suitable 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 effective surgical intervention.
- Adults aged 18–65 committed to post-operative lifestyle modifications, diet adherence, and follow-ups.
Possible Risks & Complications
While generally safe, potential risks include:
- Surgical complications such as bleeding, infection, or anesthesia reactions.
- Nutritional deficiencies (vitamins B12, D, calcium, iron).
- Dumping syndrome or gastrointestinal disturbances.
- Rare complications including leaks at the surgical site, bowel obstruction, or ulcers.
Korean hospitals minimize risks through meticulous pre-operative evaluation, advanced surgical techniques, and structured post-operative care.
Techniques & Technology Used
Korean hospitals employ advanced technology for optimal outcomes:
- Laparoscopic Roux‑en‑Y: Minimally invasive technique reduces recovery time and scarring.
- Robotic-Assisted Surgery (optional): Provides precision in complex cases.
- High-Definition Imaging & Navigation: Ensures accurate pouch creation and intestinal rerouting.
- Post-Operative Monitoring Systems: Track weight loss, nutritional intake, and metabolic parameters.
- Multidisciplinary Care: Surgeons, dietitians, endocrinologists, and psychologists collaborate for holistic patient support.
Treatment Process in Korea
- Consultation: Assessment of BMI, metabolic health, and comorbid conditions.
- Pre-Operative Testing: Blood tests, imaging, nutritional and hormonal evaluation.
- Surgery: Performed under general anesthesia, typically lasting 2–4 hours.
- Hospital Stay: Usually 2–4 days with multidisciplinary monitoring.
- Post-Operative Care: Includes dietary guidance, exercise planning, metabolic monitoring, and regular follow-up visits.
Recovery & After-Care
- Immediate Post-Surgery: Light walking, hydration, and liquid diet.
- Weeks 2–4: Gradual progression from liquid to soft foods, then solid foods with dietitian supervision.
- Nutritional Supplements: Essential vitamins and minerals to prevent deficiencies.
- Lifestyle Guidance: Balanced diet, portion control, exercise, and long-term behavioral counseling.
- Regular Follow-Ups: Monitor weight loss, metabolic parameters, and nutritional intake.
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 personalized care and comprehensive support.
