She should find a LOCAL bariatric practice for follow up before she has her surgery.
Some docs won't take patients they did. It operate on, or they charge more.
Some have "program fees" that can be hundreds of dollars or more to transfer in ( they cover the cost of the doc providing support groups and nutritional counseling and things like that ) . My dic does not charge a fee like that, but I know others do.
In the long run, it might not e cheaper to have the surgery on MX if the follow up care turns out to be more expensive here.
I saw my surgeon every 3 weeks for the first few months, then every 4-6 weeks for a while, totaling probably 8 visits in the first year.
Some of those were free follow up, then I started to pay, but because I was self pay for the surgery, my visits are only 50.00 and an additional 50.00 if I get a fill.
We see many people here who have issues and problems and don't achieve their goals partly due to improper follow up. They have insurance changes or financial problems that makes getting follow up difficult (or live far from their surgeon).
Please advise your friend tha the band may not be her best option if she is going to travel for surgery.....it could be the worst choice for her.
