Treatment Overview
Gastric Bypass Pre‑Op Assessment is a critical step in preparing patients for bariatric surgery. This comprehensive evaluation ensures that patients are physically, nutritionally, and psychologically ready for the procedure, minimizing risks and optimizing outcomes. The assessment typically includes medical examinations, blood tests, imaging studies, nutritional counseling, and psychological evaluation. Korea is recognized for offering highly thorough pre-operative assessments, leveraging advanced diagnostic technology and multidisciplinary expertise for international patients.
Purpose & Benefits
The pre-operative assessment serves several purposes:
- Determines patient suitability for gastric bypass surgery.
- Identifies underlying medical conditions that may increase surgical risk.
- Optimizes nutritional status to support recovery.
- Provides psychological evaluation to ensure readiness for lifestyle changes post-surgery.
- Reduces the risk of surgical complications and enhances long-term weight loss success.
Ideal Candidates
Pre-op assessment is recommended for:
- All adults considering gastric bypass surgery, especially those with BMI ≥ 30.
- Patients with obesity-related comorbidities such as type 2 diabetes, hypertension, or sleep apnea.
- Individuals with previous medical or surgical history that may impact recovery.
- Candidates committed to following medical, nutritional, and psychological guidance before and after surgery.
Possible Risks & Complications
