Am I A Candidate For Mini Gastric Bypass?

Factors patients and bariatric surgeons commonly review when evaluating candidacy for One-Anastomosis Gastric Bypass (OAGB).

General Candidacy Criteria

Bariatric surgery is generally considered for adults with a BMI of 40 or greater, or a BMI of 35 or greater with obesity-related conditions such as type 2 diabetes, hypertension, hyperlipidemia, or obstructive sleep apnea. Candidacy for Mini Gastric Bypass specifically depends on individual anatomy, medical history, and surgeon judgment.

Factors Commonly Reviewed

  • Body Mass Index (BMI) and weight history
  • Type 2 diabetes status, duration, and current medications
  • Acid reflux / GERD history and prior endoscopy findings
  • Previous bariatric surgery (sleeve, band, balloon, bypass)
  • Current GLP-1 receptor agonist therapy (e.g., Ozempic, Wegovy, Mounjaro, Zepbound)
  • Cardiac, pulmonary, and metabolic comorbidities
  • Nutritional status and ability to commit to lifelong supplementation
  • Psychological readiness and support systems

Situations Where Other Procedures May Be Considered

For patients with severe pre-existing reflux disease, large hiatal hernias, or other specific anatomical considerations, a surgeon may discuss Roux-en-Y gastric bypass or other procedures instead of Mini Gastric Bypass. Each patient's situation is unique and requires individualized evaluation.

What Happens In A Personalized Review

An educational candidacy review typically gathers basic medical information so the care team can describe procedures that may be relevant to your situation. It is not a clinical diagnosis or treatment plan. Formal candidacy is determined only after in-person evaluation by a qualified bariatric surgeon.
