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 health-related quality of life in first year after laparoscopic adjustable gastric banding.
BACKGROUND We analyzed the health-related quality of life ( HRQOL ) and its determinants in the first year after laparoscopic adjustable gastric b and ing ( LAGB ) .  The setting was 10 Italian public and private bariatric surgery centers . METHODS Data collected in an ongoing , prospect i ve , 3-year multicenter Italian study on the changes in HRQOL after LAGB were used . HRQOL was investigated using the Medical Outcomes Study Short-Form 36 question naire . Hunger , satiety , and the self-perceived effects of LAGB  were recorded . RESULTS A total of 334 patients were enrolled . The follow-up rate was 92.2 % . The percentage of excess weight loss was 39.6 % ± 25.8 % , with very few side effects or complications . Hunger in the morning ( 0 - 10 scale ) was 4.5 ± 2.7 before surgery and 3.8 ± 2.4 after 1 year ( P < .001 ) . Satiety after a meal ( 0 - 10 scale ) was 7.1 ± 2.7 before surgery and 8.2 ± 1.9 at 1 year ( P < .001 ) . The self-perceived effect of LAGB on caloric intake ( 0 - 10 scale ) was 8.4 ± 1.9 after 1 year . The scores for the 8 Medical Outcomes Study Short-Form 36 subscales were significantly improved after surgery . The physical component summary score was 52.6 ± 11.9 at baseline and 79.1 ± 15.6 after 1 year ( P < .001 ) . The corresponding mental component summary scores were 52.2 ± 12.3 and 76.5 ± 17.2 ( P < .001 ) . Greater physical component summary improvement was independently associated with a low initial physical component summary ( P < .001 ) , high satiety ( P = .002 ) , a high percentage of excess weight loss ( P = .013 ) , and a high self-perceived effect of the LAGB ( P = .026 ) . Greater mental component summary improvement was associated with a low initial mental component summary ( P < .001 ) , high satiety ( P < .001 ) , a low frequency of heartburn ( P = .004 ) , and a high percentage of excess weight loss ( P = .012 ) . CONCLUSIONS Significant improvements in HRQOL were observed in the first year after LAGB . A poor baseline HRQOL , a high efficacy of the b and ing in eating control , and better weight loss might influence HRQOL changes
