Changes in Quality of Life After Balloon Treatment Followed by Gastric Banding in Severely Obese Patients—The Use of Two Different Quality of Life Questionnaires
Improvements in quality of life (QOL) obtained by weight loss have mainly been reported after bariatric surgery. QOL has not been investigated in surgical patients first losing weight by nonsurgical means followed by a surgical intervention and never simultaneously by two QOL—a generic and a disease-specific—questionnaires.
Prospective data were obtained from 40 consecutive patients (mean age 36.6 years, body weight 142.4 kg, body mass index (BMI) 46.5 kg/m2). Two different QOL questionnaires, the generic Medical Outcomes Study Short Form-36 (SF-36) and the disease-specific Health-Related Quality of Life (HRQL) questionnaire, were evaluated at three points in time: at the start, 3 months after the placement of an intragastric balloon that remained in situ for 6 months, and 3 months after subsequent gastric banding.
QOL scores revealed a significant improvement in many health domains, with an earlier improvement with the disease-specific HRQL, whereas the generic QOL questionnaire lagged behind. However, in the end, the SF-36 caught up completely to normal-weight levels, whereas some scales of the HRQL remained below these levels. Work productivity and involvement in sports improved significantly. BMI declined significantly over time, but no correlation with SF-36 and HRQL score changes was found.
The QOL improved substantially independent of changes in BMI. Because of the divergent outcomes of generic and disease-specific QOL questionnaires, prospective studies should examine the sensitivity to changes of both kinds of QOL questionnaires.
