Treatment Overview
Endoscopic Sleeve Gastroplasty (ESG) is a minimally invasive, non-surgical bariatric procedure designed to help patients lose weight by reducing stomach volume. Using an endoscopic suturing device, the stomach is folded and sutured from the inside, creating a sleeve-like shape that restricts food intake and promotes early satiety.
In Korea, ESG is offered at specialized digestive and bariatric centers using advanced endoscopic technology. It is ideal for patients with moderate obesity or those seeking a non-surgical alternative to traditional sleeve gastrectomy. The procedure is performed under sedation, avoiding incisions, and allowing faster recovery with minimal downtime for international and local patients alike.
Purpose & Benefits
The main purpose of ESG is to promote weight loss and improve metabolic health without invasive surgery.
Key benefits include:
- Significant weight loss in a minimally invasive manner
- Reduced hunger and increased satiety through stomach volume reduction
- Lower risk of complications compared to surgical options
- Quick recovery with minimal downtime
- Improvement in obesity-related conditions such as type 2 diabetes, hypertension, and dyslipidemia
- Preservation of stomach anatomy for potential future interventions
Ideal Candidates
Endoscopic Sleeve Gastroplasty is suitable for patients who:
- Have a Body Mass Index (BMI) of 30–40
- Prefer a non-surgical approach to weight loss
- Have failed to achieve results with diet, exercise, or medication
- Are motivated to follow long-term dietary and lifestyle changes
International patients benefit from Korea’s expertise in advanced endoscopic procedures and comprehensive patient support services.
Possible Risks & Complications
Although ESG is considered safe, potential risks may include:
- Mild to moderate abdominal pain or nausea
- Gastrointestinal bleeding
- Infection at the suture sites
- Rare cases of leakage or perforation
- Temporary difficulty swallowing or bloating
Korean clinics perform detailed pre-procedure assessments and provide dietary and lifestyle counseling to minimize risks.
Techniques & Technology Used
Korean clinics use advanced endoscopic suturing systems to perform ESG with precision and safety. The procedure is performed under sedation and guided by real-time endoscopic visualization, ensuring accurate placement of sutures to create the sleeve.
Pre-procedure preparation includes medical evaluation, lab tests, and dietary instructions. Post-procedure follow-up includes nutritional counseling, lab monitoring, and behavioral guidance to maximize results.
Treatment Process in Korea
- Consultation & Assessment: Review of medical history, BMI, and evaluation of obesity-related conditions.
- Pre-Procedure Preparation: Fasting instructions, lab tests, and dietary counseling.
- Procedure: Endoscopic insertion of a flexible tube with a suturing device; stomach is folded and sutured to create a sleeve. Procedure lasts approximately 60–90 minutes.
- Recovery: Patients are usually discharged the same day or after an overnight stay.
- Post-Procedure Care: Gradual diet progression from liquids to solids, regular follow-up, and lifestyle counseling for sustainable weight loss.
International patients are assisted by coordinators for travel, hospital admission, and post-procedure guidance.
Recovery & After-Care
Recovery is typically quick and involves:
- Mild abdominal discomfort managed with medication
- Gradual return to normal activities within a few days
- Strict adherence to post-procedure dietary guidelines
- Regular follow-up to monitor weight loss, nutritional status, and health improvements
Patients are encouraged to maintain physical activity and long-term dietary changes to optimize outcomes.
Results & Longevity
Patients can expect:
- Average weight loss of 15–25% of total body weight within 6–12 months
- Improvement in obesity-related conditions such as type 2 diabetes and hypertension
- Enhanced satiety and reduced caloric intake
- Long-term benefits if lifestyle modifications are maintained
Results vary depending on adherence to post-procedure care and individual health conditions.
