title: Older adults fighting obesity with bariatric surgery: Benefits, side effects, and outcomes.
abstract: The aging population is growing exponentially worldwide. Associated with this greater life expectancy is the increased burden of chronic health conditions, many of which are exacerbated by the continued rise in obesity. In the US, the prevalence of obesity in adults aged 60 years and older increased from 23.6% to 37% in 2010.
  
  
  OBJECTIVE
  This review examines bariatric surgery as a treatment option for obese adults > 60 years old. The most common types of weight-loss surgery are laparoscopic adjustable gastric banding, vertical sleeve gastrectomy, Roux-en-Y gastric bypass, and the duodenal switch.
  
  
  METHODS
  A comprehensive literature search found 349 articles that referred to bariatric surgery in older adults. Of these, 70 relevant articles on bariatric surgery for older adults were utilized for this article.
  
  
  RESULTS
  Weight-loss surgery procedures were found to be equally safe for both older adults and their younger counterparts. Pre-surgical psychological assessment is critical for positive outcomes for older adults. Benefits of bariatric surgery include a decrease in comorbidities, chronic disease risk, and medication use coupled with improved mobility and quality of life outcomes. Side effects include surgical failure, changes in psychological status, and increased physical and mental stress.
  
  
  CONCLUSIONS
  Bariatric surgery can offer patients an effective and long-lasting treatment for obesity and related diseases. There does not appear to be any one bariatric procedure that is recommended for older adults, so individual needs should be taken into consideration when exploring options. Costs range from US$17,000 for laparoscopic procedures to US$26,000 for open gastric surgeries. Estimated savings start accruing within 3 months of surgery making bariatric surgery a serious cost saving consideration.
