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 .

Quality-of-Life Assessment of Morbidly Obese Patients who have Undergone a Lap-Band® Operation: 2-Year Follow-Up Study: Is the MOS SF-36 a useful instrument to measure quality of life in morbidly obese patients?
Background : Quality of life ( QoL ) was tested in a 2- year postoperative study using the Medical Outcome Study Short Form 36 ( MOS SF-36 ) to assess preoperative and 1 and 2 year postoperative QoL among one group of female patients ( group 1 , n = 42 ) and a 2 year postoperative QoL study in a second group of female patients ( group 2 , n = 9 ) who underwent a stomach reduction operation involving open surgical placement of a Lap-B and during the year 1997 . Methods : The QoL of 42 patients ( group 1 ) was assessed at most 20 hours before surgery and 1 and 2 years ( 12 and 24 months ) postoperatively using a r and omized pre-test/post-test design . The QoL of 9 patients ( group 2 ) was assessed 2 years ( 24 months ) postoperatively using a r and omized post-test design only . The results were compared with the st and ardized Dutch norm data scale . Statistical data were analyzed with SPSS versions 10.0 . Results : The placement of a Lap-B and in group 1 result ed in a significant reduction in Body Mass Index ( BMI ) in the first and second-year follow-up . Mean BMI declined significantly from 40.7 kg/m2 preoperatively to 33.1 kg/m2 at the 1-year follow-up , to 31.3 kg/m2 at 2-year follow-up . In group 2 BMI also declined significantly from 43.0 kg/m2 preoperatively to 34.2 kg/m2 at 1-year follow-up to 32.1 kg/m2 at the 2-year follow-up . Compared to the MOS SF-36 st and ardized Dutch norm data , a significant improvement in the QoL was seen on the effect variable bodily pain , mental health and general health perceptions in group 1 . Although the bodily pain , general health and mental health perceptions increased significantly 2 years postoperatively ( group 1 ) com pared with the Dutch st and ardized norm data , the preoperative general health and mental health perceptions of morbidly obese patients were , like all other preoperative effect variables , not significantly different from the scores on the Dutch st and ardized norm scale . Conclusion : Although other authors found that QoL improves after surgical-induced weight loss , showing significant improvements on patients ' perception of their health status , these findings were not confirmed in the present study . The findings show only a significant difference in bodily pain , general health and mental health perception before and after surgical intervention and preoperatively in group 1 compared to the Dutch st and ardized norm data . Because of small sample size ( n = 9 ) , no significant results were found in group 2 compared to the Dutch St and ardized norm data . Based on earlier and present findings , further study is recommended to ascertain whether the MOS SF-36 is valid in morbidly obese patients and whether the response set has an influence on QoL studies of these patients
