Weight-Loss (Bariatric) Surgery

Weight-Loss (Bariatric) Surgery Abroad: 19-Point Checklist

Bariatric surgery is not just a procedure — it is a lifelong programme of follow-up, nutrition and psychological support. Quote-shopping on price alone misses the most important part.

When to use this checklist

Use this 19-point list before booking gastric sleeve, bypass, or balloon abroad. Bariatric surgery is not a one-time event — it is a lifelong programme. Programmes that compress this into a 4-day surgical trip with no aftercare are not bariatric programmes; they are weight-loss businesses with hospital privileges.

How to use it

Insist on the psychological assessment and pre-op assessment items. If the clinic waives BMI criteria, walk away — the criteria exist because lower-BMI bariatric surgery has worse outcomes. Confirm the lifelong supplementation schedule and identify a UK GP who will manage annual blood tests before you fly out.

Red flags — walk away if you see these

No psychological assessment.
BMI requirements waived.
Surgery offered within 7 days of first enquiry.
No long-term aftercare plan.
Pre-op diet not required.
Sleeve performed in a day clinic without ICU.

Eligibility and assessment

Independent medical assessment confirming you are a suitable candidate.
NICE criteria: BMI ≥40, or ≥35 with weight-related conditions.
Psychological assessment before surgery.
Reputable bariatric programmes require this. If skipped, that is a warning.
Pre-op liver-shrinking diet 2 weeks before surgery.
Reduces surgical risk significantly.

Surgery and surgeon

Surgeon completes ≥100 bariatric cases per year.
Volume is the single strongest predictor of safety.
Surgery in a JCI- or NABH-accredited hospital with ICU.
Bariatric leaks are emergencies. ICU is not optional.
Procedure choice driven by clinical assessment, not your preference.
Sleeve vs bypass vs balloon: each has different indications.
Leak test performed intra-operatively.
This is standard practice. Confirm in writing.

Aftercare — the part that matters most

Lifelong vitamin and mineral supplementation plan.
B12, iron, calcium, vitamin D, multivitamin. Confirm in writing.
Annual blood-test schedule with a UK GP.
Your clinic should provide a template for your GP.
Dietitian follow-up at 1, 3, 6 and 12 months.
Video calls are acceptable if in-person isn't possible.
Psychological support post-surgery.
Eating disorders can shift form after bariatric surgery.
Confirm what happens if complications arise back in the UK.
NHS will treat emergencies, but elective revision is rarely funded.
