Bariatric surgery abroad: what to know before you go

Bariatric surgery has the greatest health impact of any procedure done in medical travel, and it is also the one that fits worst into a one-week package format. It is not cosmetic surgery: it is a chronic treatment that begins with an operation and continues for the rest of your life.

Who meets the criteria

Internationally accepted criteria are a body mass index of 40 or above, or 35 or above with comorbidities such as type 2 diabetes, hypertension, sleep apnoea or severe joint disease. Some scientific societies accept a BMI from 30 in poorly controlled diabetes.

The criteria exist because the risk-benefit balance changes with BMI. A clinic operating at BMI 28 on the patient's cosmetic request is outside clinical guidelines, and that tells you a lot about the rest of its practice.

Sleeve or bypass

• Sleeve gastrectomy: around 80 % of the stomach is removed, leaving a narrow tube. Technically simpler, no intestinal reconstruction, fewer nutritional deficits. It can worsen reflux.

• Gastric bypass: a small pouch is created and connected to the small intestine. More effective for type 2 diabetes and severe reflux, but it demands strict lifelong vitamin supplementation.

The choice depends on your BMI, comorbidities, reflux and habits, not on which technique is fashionable. If a centre proposes the same operation to everyone, it is individualising nothing.

What separates a good centre from a dangerous one

In bariatrics the surgeon is only one part. A serious programme includes assessment by endocrinology, nutrition, psychology and anaesthesia before surgery, and a nutritional follow-up plan afterwards. Psychological assessment is not bureaucracy: untreated binge eating disorder is one of the most common causes of failure at three years.

Also ask about the protocol for a staple-line leak, the most feared serious complication: whether the centre has its own ICU, interventional radiology and endoscopy available 24 hours a day. A centre without an ICU should not be doing bariatric surgery.

Recovery and the flight home

The usual stay is two to four hospital nights and seven to ten days in the country before flying. Flying earlier raises clot risk and leaves the leak window uncovered, which typically falls between day three and day seven.

Diet progresses in phases: clear liquids, full liquids, purees, soft foods and solids, over roughly six to eight weeks. You need that plan in writing and in your language before leaving hospital.

The lifelong follow-up almost no package includes

After bariatric surgery you must monitor iron, vitamin B12, vitamin D, calcium, folate and protein for life, with periodic blood tests and daily supplementation. Without that monitoring, anaemia, osteoporosis and, in extreme cases, neurological complications appear.

This is your responsibility and your local doctor's, not the foreign clinic's. So before travelling you should already have an endocrinologist or family doctor informed and willing to handle follow-up.

Indicative prices

3,000 to 6,000 euros in Turkey or Mexico, 6,000 to 9,000 in central Europe, 15,000 to 25,000 in the United States. Check whether the price covers hospital nights, pre-operative endoscopy, compression stockings, anticoagulation and management of a possible complication.

Red flags

• Operating without prior psychological and nutritional assessment.

• Accepting a BMI below the clinical criteria.

• Hospital discharge within 24 hours.

• A return flight scheduled before day seven.

• A centre with no ICU or emergency endoscopy.

• No written supplementation plan.

Bariatric surgery changes lives when it is part of a programme. When it is sold as a standalone operation with a hotel included, the weight returns or the patient ends up in a local emergency department with no medical records.
