The Impact of Preoperative Body Weight on Quality of Life after Surgical Treatment for Morbid Obesity

Abstract

Introduction and Purpose: Although the effect of bariatric treatment on quality of life has already been unambiguously confirmed, many of its aspects have not yet been fully studied. A study was planned to analyze an effect of surgical treatment for obesity with the laparoscopic sleeve gastrectomy (LSG) or the laparoscopic gastric bypass on quality of life of treated patients, depending on the obesity stage on qualification for bariatric treatment. Material and Methods: The studied group consisted of 130 patients treated for super obesity. Overall, 68 (52%) patients underwent LSG, and the remaining group of 62 (48%) patients underwent laparoscopic Roux-en-Y gastric bypass. In the whole studied group, the mean body mass index (BMI) value was 50.44 kg/m2. The studied group of patients was divided into two subgroups: with initial BMI of <50 kg/m2 (morbid obesity) and of >50 kg/m2 (super obesity). In both groups, quality of life was assessed by using the SF-36 questionnaire both before initiation of treatment and 1 year after the surgery. Results and Conclusion: The recorded quality of life was very poor in all patients, regardless of the initial BMI value. The surgical treatment resulted in a significant reduction in body mass. The mean excessive BMI loss (%EBMIL) was 68.05%. The surgical treatment resulted in a significant improvement in all quality-of-life parameters. No significant relationship was found between the improvement in quality of life and initial BMI or the type of surgery.
