Banded Gastric Bypass: Eligibility Criteria

Typical criteria for banded gastric bypass (gastric bypass with a restrictive ring/band):

1. BMI ≥ 40 or BMI ≥ 35 with ≥1 obesity-related comorbidity (type 2 diabetes, hypertension, sleep apnea, etc.).
2. Documented failure of nonsurgical weight loss (diet, exercise, behavioral therapy).
3. Commitment to lifelong dietary, exercise, and follow-up adherence.
4. No prohibitive surgical risk (e.g., severe cardiopulmonary disease, uncontrolled psychosis, active substance abuse).
5. Negative pregnancy test (if applicable) and willingness to avoid pregnancy during rapid weight loss phase.
6. Psychological evaluation confirming understanding of risks/benefits and readiness for lifestyle change.

Criteria may vary slightly by program and insurer. A multidisciplinary bariatric team makes the final determination.
