The average impact of bariatric surgery on quality of life corresponded to an effect size of 0.88 ( 95 % CI : 0.80 - 0.96 ) , indicating that bariatric surgery has a significant positive influence on quality of life in general .
The impact varied considerably across studies with bariatric surgery showing a significantly greater positive influence on physical quality of life compared to mental quality of life .
Bariatric surgery is effective in improving quality of life , especially when looking at physical well-being .
Greater focus on the psychological well-being of the person undergoing surgery for obesity may lead to a better post-surgery prognosis for more people
This study aims to review the obesity literature in order to assess the impact of bariatric surgery on quality of life and the between- study variation by examining the st and ardized mean magnitude of effect in change in the levels of quality of life .
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
