Bariatric surgery in Mexico: costs, hospitals and what to expect
Sleeve gastrectomy and bypass in Tijuana and Monterrey, and why the follow-up programme matters more than the surgical price.
Mexico is the largest bariatric destination in the Americas, and increasingly used by European patients too. A sleeve gastrectomy is typically £3,400 to £4,300 and a gastric bypass £4,400 to £5,200, against £9,000 to £13,000 privately in the UK.
Bariatric surgery is the clearest case in medical travel where the operation is the cheap, easy part. Outcomes at five years correlate with dietetic follow-up, nutritional monitoring and psychological support — none of which travel home with you.
What you will actually pay
Compared against private rates in the UK, Western Europe and the Gulf. Most of our readers travel from one of those three, so measure the saving against your own market rather than ours.

What to weigh before you book
The complication that matters most is an anastomotic or staple-line leak, which typically presents between days 3 and 10 — that is, around the time you are flying home or shortly after. Symptoms are tachycardia, fever and abdominal pain. Know them, and know which UK hospital you would go to, before you travel.
The longer-term risk is nutritional. Bypass patients need lifelong B12, iron, calcium and vitamin D monitoring. UK GPs will usually prescribe supplements but may not have the specialist bariatric follow-up pathway that an NHS-operated patient gets automatically. Arrange who is monitoring your bloods before you fly, not after.
How to choose between clinics
Ask whether a leak test is performed before discharge and whether a dietitian is part of the team rather than a single consultation. Ask what the twelve-month follow-up programme actually consists of and how it is delivered remotely. A clinic that has thought seriously about that is a clinic that has thought about outcomes.
Frequently asked questions
Will my GP support me afterwards?
Most will prescribe supplements and run bloods, but you may not get the structured bariatric follow-up that NHS-operated patients receive. Speak to your GP before you travel so there is a plan rather than a surprise.
How soon can I fly after bariatric surgery?
Usually five to seven days, with clearance after a leak test. The concern is presenting with a leak at altitude or far from the operating team, not the flight itself.
Sleeve or bypass?
A clinical decision based on BMI, reflux, diabetes and eating patterns — not price. If a clinic recommends a procedure before reviewing your history and bloods, get another opinion.
What if I regain the weight?
Regain at five years is common without follow-up and is the strongest argument for paying for a structured programme. Revision surgery is more expensive and carries higher risk than the original operation.
Is Tijuana safe?
The medical district serving international patients is well established, and reputable hospitals arrange transfer directly from San Diego. Follow the clinic's transfer arrangements rather than travelling independently, and check current government travel advice.
