TLDR
Assessment of the incidence and causative factors associated with weight regain following bariatric surgery and a systematic approach to patient assessment focusing on contributory dietary, psychologic, medical and surgical factors are conducted.Abstract:
Obesity is considered a worldwide health problem of epidemic proportions. Bariatric surgery remains the most effective treatment for patients with severe obesity, resulting in improved obesity-related co-morbidities and increased overall life expectancy. However, weight recidivism has been observed in a subset of patients post-bariatric surgery. Weight recidivism has significant medical, societal and economic ramifications. Unfortunately, there is a very limited understanding of how to predict which bariatric surgical patients are more likely to regain weight following surgery and how to appropriately treat patients who have regained weight. The objective of this paper is to systematically review the existing literature to assess the incidence and causative factors associated with weight regain following bariatric surgery. An electronic literature search was performed of the Medline, Embase and Cochrane library databases along with the PubMed US national library from January 1950 to December 2012 to identify relevant articles. Following an initial screen of 2,204 titles, 1,437 abstracts were reviewed and 1,421 met exclusion criteria. Sixteen studies were included in this analysis: seven case series, five surveys and four non-randomized controlled trials, with a total of 4,864 patients for analysis. Weight regain in these patients appeared to be multi-factorial and overlapping. Aetiologies were categorized as patient specific (psychiatric, physical inactivity, endocrinopathies/metabolic and dietary non-compliance) and operation specific. Weight regain following bariatric surgery varies according to duration of follow-up and the bariatric surgical procedure performed. The underlying causes leading to weight regain are multi-factorial and related to patient- and procedure-specific factors. Addressing post-surgical weight regain requires a systematic approach to patient assessment focusing on contributory dietary, psychologic, medical and surgical factors.read more

Weight Regain and Insufficient Weight Loss After Bariatric Surgery : Definitions, Prevalence, Mechanisms, Predictors, Prevention and Management Strategies, and Knowledge Gaps—a Scoping Review
TL;DR: A scoping review of weight regain and insufficient weight loss after bariatric surgery is presented in this paper. But, the focus of the review was on the effects of weight regaining (WR) or insufficient weight reduction (IWL).

TL;DR: Early postoperative weight loss can be used to identify patients whose predicted weight loss trajectories are suboptimal and early targeting of poor responders with more intensive postoperative lifestyle and behavioural support could potentially enhance their weight loss response.

TL;DR: The results of this study confirm that %TWL should be the metric of choice when reporting WL because it is less influenced by preoperative BMI.

How to Choose and Use Bariatric Surgery in 2015
TL;DR: Evidence is provided to support surgical treatment of severe obesity to achieve cardiovascular disease risk reduction in severely obese patients, and studies on postoperative outcomes, investigations on weight loss physiology, and mechanism of action after bariatric surgery provide a better understanding of the bariatric Surgery metabolic benefits.

TL;DR: Below the range 22.5-25 kg/m(2), BMI was associated inversely with overall mortality, mainly because of strong inverse associations with respiratory disease and lung cancer, despite cigarette consumption per smoker varying little with BMI.

TL;DR: In this paper, the authors estimated trends and their uncertainties of mean BMI for adults 20 years and older in 199 countries and territories, and used a Bayesian hierarchical model to estimate mean BMI by age, country, and year.
A Systematic Review and Meta-analysis
TL;DR: A systematic review of studies published from January 1, 1950, through November 31, 2008 using PubMed, EMBASE, Web of Knowledge, CINAHL, and all Evidence-Based Medicine Reviews found that randomized clinical trials and prospective studies of RRTs that reported data on changes in the primary outcome of hospital mortality or the secondary outcome of cardiopulmonary arrest cases were included.
