What is the effect of bariatric surgery on health-related quality of life in people with obesity? observational cohort analysis of the United Kingdom national bariatric surgery registry.

In this large dataset, greater weight loss and T2D remission were independently associated with greater improvements in HRQoL following bariatric surgery. The HRQoL-BMI relationship for people undergoing bariatric surgery differs to that which has previously been estimated following behavioural interventions. Use of the estimates generated here will be important for clinical and political decision making.
