Choosing a bariatric surgery clinic

A short, factual guide to comparing bariatric (weight-loss) surgery clinics — sleeve versus bypass, the long-term follow-up that matters most, and how to read a clinic's GCR Rating for bariatric surgery.

Last updated

Bariatric surgery is a major, life-long change, not a single procedure. The clinics that get the best results treat follow-up care as seriously as the operation itself — and that is what this guide helps you compare.

The procedures, in plain terms

Sleeve gastrectomy

A large part of the stomach is removed, leaving a smaller “sleeve”. It is widely performed and does not reroute the intestine.

Gastric bypass

The stomach is made smaller and the small intestine rerouted, which changes how food is absorbed. It can give greater results for some patients but needs careful lifelong nutritional follow-up.

There is no single best option

The right procedure depends on your health, weight, and other conditions. A good clinic recommends a procedure after assessing you — not before.

Follow-up is part of the treatment

Results depend heavily on the support after surgery: dietitian input, vitamin and mineral monitoring, and medical review over months and years. Ask exactly what aftercare is included, how it works once you are back home, and how the clinic handles complications.

How the GCR Rating for bariatric surgery works

What the number means

A clinic's GCR Rating for bariatric surgery is a single score out of 5, calculated from verified patient reviews and — increasingly — patient-reported outcomes for this specialty, using a model that accounts for how many reviews a clinic has. No clinic can pay to change it.

Use it as a first filter, then confirm the assessment, hospital and follow-up details above. See how each GCR Rating is calculated →
