Quality of life in bariatric surgery

Background: Bariatric surgery is the treatment of choice for morbid obesity. Since bariatric operations alter gastrointestinal anatomy, they may induce symptoms that have a negative impact on quality of life (QOL). The aim of this study was to prospectively analyze QOL after bariatric surgery. Methods: The QOL index questionnaire (GIQLI) was applied to 45 surgically treated morbidly obese patients (15 vertical banded gastroplasty, 15 Roux-en-Y gastric bypass (RYGBP), and 15 distal RYGBP) and to 15 non-operated morbidly obese controls. Follow-up was of 1-year minimum. The GIQLI evaluates physical and mental well-being, digestion and bowel habits. Results: Physical and mental well-being as well as the overall QOL were significantly higher in the operated patients. There were no significant differences in digestion and bowel habits between the groups. Differences in QOL were not related to the type of surgical procedure. Conclusion. Overall QOL was significantly better in operated than in non-operated patients. There is no negative impact of bariatric surgery on QOL related to GI symptoms.
