Obesity

Impact of bariatric surgery on monthly earnings and employment: a national linked data study in England, 2014–2022

Int J Obes (Lond)Published Retrospective cohort study

Authors' conclusion

Bariatric surgery is associated with an increased probability of being employed, resulting in increased earnings. This suggests that living with obesity negatively impacts labour market outcomes and that obesity management interventions are likely to generate economic benefits both to individuals and on a macroeconomic level by increasing the likelihood of employment of people living with obesity.
