If the facility cannot manage a leak at 3am, nothing else on the brochure matters.
Bariatric surgery is major abdominal surgery on patients with higher anaesthetic risk. An intensive care unit in the same building — not 'nearby' or 'affiliated' — is the single most important thing to verify.
Ask how many bariatric cases the surgeon performs annually. Outcome data consistently links higher volume to lower complication rates, in every country studied.
Ask what happens at months 1, 3, 6 and 12; who provides dietitian support and in what language; and what bloods are checked and when. A clinic that answers only about the operation is selling a procedure, not treating obesity.
What happens if there is a complication after you fly home? Which hospital do you go to, who communicates with your local surgeon, and who pays? Get this in writing before booking, wherever you go.
Generally yes with clearance, compression stockings, hydration and movement during the flight — but only after a normal post-operative check.
