Getting a Second Opinion on Bariatric Surgery
Most people who come to us for a second opinion apologise for it. There is nothing to apologise for — on a decision this size, a second read is ordinary medicine.
Book a second-opinion consultationWhen a second opinion is worth seeking
There is no threshold you have to meet. But there are situations where a second read reliably adds something.
- You have been told nothing can be done. Options in this field have changed considerably, and a page of them did not exist a decade ago.
- You have been offered one option and only one. Revision, endoscopic approaches and medication are different tools; if only one was discussed, it is fair to ask why.
- The weight has come back and nobody has explained why. The cause determines the fix, and "eat less" is not a diagnosis.
- You have symptoms that keep being attributed to something else. Reflux, pain, vomiting and difficulty eating are worth a second look.
- Your original surgeon is no longer available — retired, moved, or a practice that has closed. This is more common than people expect and is a perfectly good reason.
- You simply do not feel heard. That is reason enough.
It is not disloyalty, and it is not starting over
Patients hesitate because a second opinion feels like going behind someone’s back. It is not. Surgeons refer for second opinions routinely, and a good one is not offended by the request.
It also does not mean abandoning your existing care. Plenty of second opinions end with the patient returning to their original surgeon, better informed and with a clearer plan. The point is the information, not the transfer.
What to bring
A second opinion is only as good as what it has to work with, and the single most useful document is the one people most often arrive without.
- The operative report from your original procedure. It states exactly what was done, which is not always what the patient was told. Request it early — obtaining records from another practice takes time.
- Any imaging or endoscopy reports, and the images themselves where you can get them.
- Your weight history over time, roughly, rather than a single figure.
- A current medication list, including anything for weight.
- A written list of your questions. Consultations move quickly and the important question is the one people remember afterwards.
What a good second opinion gives you
It should explain what your current anatomy is and what it means, in language you can repeat to someone else. It should set out more than one route where more than one exists, including doing nothing for now. And it should be honest about what is not known without more information.
Eligibility for a bariatric procedure follows the 2022 ASMBS/IFSO indications — a BMI of 35 or above regardless of co-morbidity, or 30 to 34.9 with metabolic disease, with lower thresholds for patients of Asian descent. These replaced the 1991 criteria that a great deal of older material still repeats, which is itself a reason some patients were told years ago that they did not qualify when today they might.
The answer may be that you do not need anything
This is worth saying plainly on a page published by a surgical practice. A meaningful proportion of second opinions conclude that no further procedure is indicated — that the anatomy is intact, that the regain is modest and better addressed another way, or that the risk of operating outweighs the likely benefit.
That is a legitimate outcome and not a wasted appointment. Knowing that surgery is not the answer is worth as much as being told it is.
Booking one
If you are considering it, request your operative report first — everything else is easier once you have it. Consultations here are complimentary, and a second opinion is a normal reason to book one.
