Cost of obesity recurrence

Abstract

Bariatric surgery allows patients to lose a substantial proportion of their excess body weight; however, over time this weight may slowly return. This chapter will discuss the financial impact of obesity and its management through surgical intervention, as well as the rate of weight recurrence after bariatric surgery. The mechanistic and patient behavioural causes of this weight regain will be discussed. Revisional procedures are the current approach to modifying obesity recurrence, and various management options will be reviewed. Additionally, the costs of this endeavour, as well as the tools for evaluating costs and the economic impact of bariatric surgical revision, will be explored.
