Ranked by GCR Rating (out of 5). No stars, no review counts — one fair number per facility.

Compiled independently by GCR since 2012 from verified patient reviews — no clinic can pay to change its Rating. How this data is verified →

GCR ranks 109 bariatric surgery clinics across 11 countries.
Each clinic's GCR Rating is computed from verified patient reviews using a Bayesian model that weighs rating, review volume and recency — not a simple average.
Clinics with fewer verified reviews are pulled toward the bariatric surgery specialty-wide average rather than excluded, so any clinic with verified reviews can be ranked.
Rankings are refreshed on a regular cycle as new verified reviews come in.

Frequently asked questions

What does the GCR Rating measure for bariatric surgery clinics?

The GCR Rating is computed from verified patient reviews — rating, volume and recency — using a Bayesian model, not a simple average, and that calculation is the same for every specialty GCR ranks. Clinics in this ranking provide procedures such as gastric sleeve, gastric bypass and gastric banding — because long-term weight-loss success depends heavily on post-surgical support, patients typically weigh aftercare and dietitian access alongside the surgery itself. See the full methodology for the exact formula.

Is the GCR Rating the same as a clinic's Google star rating?

No. The GCR Rating is a separate score (out of 5, to three decimals) computed from verified review rating, volume and recency using a Bayesian model — not a simple star average. Two bariatric surgery clinics with the same Google star rating can end up with different GCR Ratings once volume and recency are factored in.

Does a bariatric surgery clinic need a minimum number of reviews to be ranked?

There's no fixed cutoff. GCR's Bayesian model pulls a clinic's average toward the bariatric surgery specialty-wide mean in proportion to how few verified reviews it has — so a clinic with limited review history starts near the typical score for the specialty and earns its way up or down as more verified reviews accumulate, rather than being excluded outright.

How often is this ranking updated?

Rankings are refreshed on a regular cycle as new verified reviews come in, so a bariatric surgery clinic's position can move up or down over time as its underlying review data changes.

What does it mean if a bariatric surgery clinic isn't listed here?

GCR ranks clinics it has verified review data for. If a clinic you're considering isn't listed, you can suggest it for review — GCR will look into adding it once enough verified patient data is available.
