# 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.

## 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.

## Red flags

- 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.

## Frequently asked questions

**Q: Why is bariatric surgery different from other procedures abroad?**

A: Because it is a lifelong programme, not an event. Nutrition, monitoring and psychological support continue for years. A programme that compresses this into a four-day surgical trip with no aftercare is not a bariatric programme; it is a weight-loss business with hospital privileges.

**Q: What are the red flags in a bariatric package?**

A: No psychological assessment; BMI requirements waived; and surgery offered within seven days of first enquiry. Each is a screening step removed to close a sale, and each exists because patients who should not have the operation sometimes ask for it.

**Q: Why does psychological assessment matter?**

A: Because the operation changes what you can eat, not why you eat. Food-relationship issues frequently surface in the second year, and a programme that never assessed them at the start has no plan for them when they arrive.

**Q: What aftercare should be in place before I book?**

A: A named UK bariatric dietitian or specialist nurse who will accept your case, and a GP willing to monitor bloods and prescribe the recommended supplements. Arrange both before surgery — the follow-up is what determines the long-term result.
