Commonly considered contraindications

Untreated severe psychiatric illness or active substance use disorder that would prevent safe peri-operative care or follow-up.
Active malignancy where surgery would interfere with cancer treatment.
Severe untreated cardiopulmonary disease that makes general anesthesia unsafe.
Unwillingness or inability to commit to long-term follow-up, dietary changes, and supplementation as required.
Pregnancy or plans for imminent pregnancy (timing of any bariatric surgery should be coordinated with the obstetric team).
Anatomical findings that preclude safe anastomosis formation.
Other patient-specific factors identified during medical, anesthetic, nutritional, and psychological evaluation.

This list is not exhaustive. Final eligibility must be determined by a qualified surgical and metabolic team after individual evaluation.
