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 .
Two-year changes in generic and obesity-specific quality of life after gastric bypass
The study objectives were to assess 2-year changes in health-related quality of life ( HRQL ) after gastric bypass in patients with severe obesity and to analyze HRQL improvements in relation to weight loss after bariatric surgery . This was a prospect i ve intervention study with consecutive patients referred to two bariatric surgical units in the Basque Country . We used both generic ( Short Form Health Survey , SF-36 and EuroQol , EQ-5D ) , and specific question naires ( Moorehead-Ardelt , MA II and Obesity-related Problems Scale , OP ) . Effect sizes and receiver operating characteristic ( ROC ) curves were calculated to assess the change in quality of life . Spearman ’s correlation coefficient was calculated to assess whether there was an association between changes in body mass index ( BMI ) and HRQL . Of 82 patients who underwent surgery , 79 were followed-up for 2 years . Mean weight loss was 37 % of body weight ( 49 kg ) and BMI fell from 50.6 to 31.8 . The initial problems and final improvements were greater in the physical dimensions . Considerable benefits were observed in assessment s with all the instruments used . However , the changes in weight/ BMI and HRQL were not linear . The comparison with general population showed a similar profile in SF-36 dimensions after surgery . Severely obese patients have lower perceived health across all dimensions of quality of life . Moreover , the impact on functioning is so important that severe obesity can be described as a cause of disability that disappears 2 years after surgical treatment . ROC curves indicate that most of the HRQL measures are poor predictors of change in terms of reduction in body weight or BMI
