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 .
Quality of life following laparoscopic gastric banding in patients with morbid obesity.
In a prospect i ve study of 188 patients with morbid obesity , the time-dependent changes in the quality of life of individual patients were analyzed following laparoscopic gastric b and ing ( LGB ) . These 188 patients ( 148 females and 40 males ; age 19 to 59 years ; body mass index 33 to 72 kg/m(2 ) ) underwent evaluation  of  the LGB according to a strict protocol that included psychological testing using st and ardized instruments , detailed medical evaluation , upper gastrointestinal function studies , and evaluation of quality of life using the Gastrointestinal Quality of Life Index ( GIQLI ) . Following this evaluation , 73 patients ( 57 females and 16 males ; age 37 years [ range 19 to 59 years ] ; body mass index 48 kg/m(2 ) [ range 37 to 72 kg/m(2 ) ] ) underwent  LGB and were followed up for 2 years focusing on weight loss , postoperative morbidity , weight-related comorbidity , and quality of life . The results demonstrate that LGB is well able to allow for a significant loss of excess weight and a significant improvement in patients ' quality of life , both after a rather short period of time after surgery and at a continuous rate throughout the follow-up . The price for this success that was found in approximately 90 % of patients is a complication rate of 38 % ; 85 % of these patients , almost one third of all patients , must undergo some type of revision surgery . However , once the complications are resolved , these patients achieve the same level of weight loss and improvement in quality of life as patients with an uncomplicated postoperative course
