Quality of Life After Bariatric Surgery.

Purpose Of Review: The purpose of this review is to provide an introduction to quality of life (QOL) outcomes after bariatric surgery and a summary of the current evidence.

Recent Findings: QOL has been emphasized in bariatric surgery since the NIH Consensus Conference statement in 1991. Initial studies were limited to 1- and 2-year follow-up. More recent findings have expanded the follow-up period up to 12 years, providing a better description of the impact on long-term QOL. Overall, there is little to no consensus regarding the definition of QOL or the ideal survey. Bariatric surgery has the greatest impact on physical QOL, and the impact on mental health remains unclear. There are some specific and less frequently reported threats to quality of life after bariatric surgery that are also discussed. Obesity has a definite impact on quality of life, even without other comorbidities, and surgery for obesity results in significant and lasting improvements in patient-reported quality of life outcomes. This conclusion is limited by a wide variety of survey instruments and absence of consensus on the definition of QOL after bariatric surgery.
