Am I a Candidate for Bariatric Surgery?

Guidance on candidacy has evolved: the 2022 ASMBS/IFSO joint guidelines recommend that surgery be considered for a BMI of 35 or above regardless of whether a weight-related health condition is present, and for a BMI of 30–34.9 in people with type 2 diabetes or other metabolic disease, regardless of prior treatment response. Some insurers, however, may still apply older, stricter criteria for coverage purposes, so it's worth checking your specific plan. These thresholds guide the conversation — they don't replace it.

Beyond BMI: The Full Evaluation

A real candidacy evaluation is multidisciplinary and typically includes a review of your medical history, prior weight-loss attempts, current medications, and a psychological evaluation — not to disqualify you, but to check readiness for the major, permanent lifestyle changes surgery requires and to identify anything (like an untreated eating disorder) that needs addressing first.

Committing to Long-Term Follow-Up

Because bariatric surgery requires lifelong nutritional monitoring (see our vitamins and supplements guide), surgeons also assess your ability to commit to regular follow-up visits and lab work — not just the operation itself.

Which Procedure Might Fit

Candidacy doesn't stop at "yes" or "no" — it also shapes which procedure may suit you best. See our gastric sleeve vs. gastric bypass comparison, and if you haven't yet tried medication, our bariatric surgery vs. GLP-1 injections guide.
