There are members here who've had it but it's not something I'd do. As mentioned above, post-op care is so important and that should involve the same medical team you use for the surgery. I learned long ago very few doctors want to offer post-op care where another doctor did the surgery.
You're taking a big risk with your longterm health and I think people really need to look at their motivations for wanting the surgery. This is major surgery. The point shouldn't be cosmetic. It should be used holistically to improve all your systems to address your comobidities AND it's not cookie-cutter. One size does not fit all.
if money or lack of insurance is the problem, you should find a hospital that offers scholarships that might pay 80 percent of the cost so you can have 100 percent of the benefits to your health. That's what I did and part of the deal was that I enrolled in a university study for two years, which was a great thing for all doctors, interns, dieticians and researchers who were involved. My journey was documented as a case study and published in JAMA.
IMO going to Mexico or some other place you can get inexpensive surgery is like placing a bet and hoping you win the jackpot, without going all in. You'd be relying more on luck than on science. I'm sure there are fine doctors in Mexico but if you want continuity of care, you should really move to Mexico on a visa for as long as it takes to get safe and thorough care until you're healed and have been checked out nutritionally.
