I, too, pursued the new GLP-1 RAs after I put back on almost half of the weight I had lost due to the surgery, which took about a decade.

I suppose I think of revision surgery as something to do if an original surgery fails, for various definitions of fail. In my case, I did not consider the original surgery a failure -- the weight regain traced to other problems. (Although, to be fair, part of it was a mishandling of post-surgical dumping, which left me with some bad habits.)

I have more recently contemplated a knee replacement, and approached it in a more knowledgeable way, digging more deeply into side effects and success statistics. In fact, I specifically went for a second opinion with a surgeon who specializes in revision surgery.

So that would be my first suggestion: look for a surgeon who has done a lot of revision surgery, which might mean a long wait for an initial consultation, since these people are not thick on the ground. My second would be to clearly understand what is driving you to contemplate revision surgery -- what "success" looks like to you. What, exactly, do you regret about the first surgical outcome that you are trying to fix? My third would be to poke hard into the extent to which the outcomes might be worse instead of better a second (or third) time around. And last but not necessarily least, make sure you explore the question of insurance coverage for revision surgery -- I have no idea what the circumstances are under which an insurance company would pay for this.
