Only outcomes of the IWQoL , SF-36 and OWQoL show QoL outcomes that exceed community norms .
The QoL is increased after bariatric surgery on both the short and long term .
However , due to the heterogeneity of the studies and the generality of the question naires is it hard to make a distinction between different surgeries and difficult to see a relation with medical profit .
Currently the effects of bariatric surgery are generally expressed in excess weight loss or comorbidity reduction .
Therefore the aim of this review was to provide insight in the available prospect i ve evidence regarding the short and long-term effects of bariatric surgery on Quality of Life ( QoL ) and a comparison with community norms .
Improvement in Quality of Life After Laparoscopic Sleeve Gastrectomy
Few studies have investigated changes in health-related quality of life ( HRQOL ) in surgical patients who have undergone a laparoscopic sleeve gastrectomy .  Prospect i ve data were obtained from 78 consecutive patients undergoing laparoscopic sleeve gastrectomy ( LSG ; mean age , 42.4 years ; mean body weight , 131 kg ; mean body mass index ( BMI ) , 47 kg/m2 ( 24.4 % of superobese patients ) ) . Two HRQOL question naires were administered preoperatively and 12 months postsurgery : the generic Medical Outcomes Study Short Form-36 and the weight-specific IWQOL-Lite question  naire . Excess weight loss at 12 months was 57.18 % . No mortality was recorded . HRQOL scores revealed a significant improvement in all areas of both question naires . However , changes in HRQOL were not associated consistently with amount of weight loss .  Laparoscopic sleeve gastrectomy is an effective and safe procedure , with positive changes in health-related quality of life as well as weight reduction . A fruitful area for future research is the investigation of long-term changes in HRQOL after LSG
