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 .
The Impact of Psychological Support on Weight Loss Post Weight Loss Surgery: a Randomised Control Trial
Background The purpose of the present study is to evaluate the impact of a health psychology-led bariatric rehabilitation service ( BRS ) on  patient weight loss following bariatric surgery  at 1 year . Methods A single-site open-r and omised parallel group control trial based at St. Richard ’s Hospital in Chichester in the UK . Patients ( n = 162 ) were recruited immediately prior to Roux-en-Y gastric bypass  and r and omly allocated to receive either treatment as usual ( n = 80 ) or the BRS ( n = 82 ) . The BRS involved three 50-min one-to-one sessions with a health psychologist and provided information , support and mentoring pre and post surgery addressing psychological issues such as dietary control , self esteem , coping and emotional eating . Weight loss was assessed at 1 year . The key outcome variable was BMI and change in BMI . Results Follow-up weight was available for 145 patients . Intention-to-treat analysis ( n = 162 ) using last measured weights showed that mean change in BMI by 1 year post surgery was −16.49 . There was no significant difference between the two groups ( control group = −16.37 , 95 % CI = 15.15–17.57 ; intervention = −16.6 , 95 % CI = 15.42–17.81 ; ηp2 = 0.001 ) . Similarly , explanatory analysis ( n = 145 ) showed a mean change in BMI of −17.17 . The difference between the two groups was not significant ( control group = −16.9 , 95 % CI = 15.78–18.18 ; intervention = −17.35 , 95 % CI = 18.5–16.16 ; ηp2 = 0.001 ) . Conclusions Psychological support pre and post bariatric surgery had no impact on weight loss as measured by BMI and change in BMI by 1 year . It is argued that psychological support should be targeted to patients who start to demonstrate  weight regain at a later stage . Trial registration : Clinical Trials.gov NCT01264120
