Treatment Overview
Roux‑en‑Y Gastric Bypass is a highly effective bariatric surgery that helps patients achieve long-term weight loss by reducing stomach size and bypassing a portion of the small intestine. This procedure limits calorie absorption and alters digestive hormones, aiding in appetite suppression and metabolic improvement. Korea is recognized globally for performing this surgery with advanced technology, experienced surgeons, and comprehensive care for international patients.
Purpose & Benefits
The surgery is designed to address severe obesity and its related health conditions. Benefits include:
- Significant and sustained weight loss.
- Improvement or remission of type 2 diabetes, hypertension, and sleep apnea.
- Increased energy, mobility, and quality of life.
- Reduced risk of obesity-related complications such as heart disease and stroke.
Ideal Candidates
Roux‑en‑Y Gastric Bypass is suitable for:
- Individuals with a BMI of 40 or higher.
- Patients with a BMI of 35–39.9 who have obesity-related health issues.
- Adults aged 18–65 who have not achieved weight loss through diet, exercise, or medication.
- Individuals committed to post-surgery lifestyle changes, including diet and exercise.
Possible Risks & Complications
While generally safe, the surgery carries some risks:
- Bleeding, infection, or adverse reactions to anesthesia.
- Nutritional deficiencies (vitamins B12, D, calcium, iron).
- Dumping syndrome, causing nausea or diarrhea after certain foods.
- Potential for bowel obstruction or hernias.
- Rare complications such as leaks at the surgical site or ulcers.
Korean clinics mitigate these risks with advanced surgical techniques, thorough pre-operative evaluations, and detailed post-operative care.
