Weight loss (bariatric) surgery is a treatment for people who are severely obese. The main types are gastric bypass, gastric band, gastric balloon and sleeve gastrectomy. To be considered on the NHS you will usually need a body mass index (BMI) of 40 or more and to have tried other ways of losing weight.
Most people go home 1 to 3 days after surgery. Hospital-level numbers for this operation are not published as open data, so this page shows NHS waiting times for general surgery and waits for gastroscopy.

How to read this
- Not a ranking. The table is in alphabetical order. A higher volume does not on its own mean better care, and we do not combine the columns into a score.
- Risk adjustment. Where a figure says “adjusted”, the audit has allowed for differences in the patients each hospital treats, such as age and other illnesses. Hospitals that take on more complex cases can still look different for reasons the adjustment does not capture.
- Bands and limits. We only say a result is higher or lower than expected when the source itself says so (for example NJR outlier status, NELA funnel limits, SSNAP levels, CQC survey bands). Where the source publishes a rate without limits we show the rate and the national figure, and say “No banding published”.
- Small numbers. A small hospital can have 0% or a high percentage by chance. Figures the source suppresses are shown as “Not published (small numbers)”.
- Trust or hospital. This audit publishes figures for each NHS trust, which may run several hospitals. The operation may only be done at one of them.
- Different periods. Each figure has its own period, shown next to it. Audit results describe operations done one to three years ago; waiting times are updated monthly.
- Talk to your GP or consultant about what the figures mean for you. If you are referred for planned care in England, you can usually choose your hospital.
