Health-related quality-of-life in patients with morbid obesity after gastric banding for surgically induced weight loss.
BACKGROUND Physical , emotional , and social functioning are impaired in obesity . It is unknown whether and , if so , to what extent and in which domain obese subjects who lose weight may catch up to normal-weight levels . Our objective was to compare the health-related quality -of-life ( HRQL ) of obese subjects with that of a normal-weight reference group before and 1 year after a weight loss program that centered around laparoscopic and open gastric b and ing . METHODS An HRQL question naire consisting of a battery of both generic and specific measures was administered to 50 morbidly obese subjects on 2 occasions and to 100 healthy , normal-weight subjects , matched for age , gender , education , and vocational training . In addition to weight loss and health gain , the influences of achieved weight loss goals , satisfaction with outcome and operative approach ( laparoscopy/laparotomy ) were assessed . RESULTS Quality -of-life was significantly impaired in obese subjects . With a substantial weight loss of 35 kg and 42 % loss of excessive weight , and correction of disturbed metabolic parameters , they significantly improved in general well-being , health distress , and perceived attractiveness , approaching halfway the values of a normal-weight reference group . Improvement in values for depression and self-regard lagged behind . In physical activity , they bypassed the reference group . Days of sick leave decreased to the level of the reference group . Improvements in HRQL paralleled the rate of weight loss . Personal satisfaction and surgical approach were of minor influence . CONCLUSIONS The obese subjects ' impaired physical and social functioning improved considerably , catching up midway to normal-weight reference values after weight loss . Psychologic amelioration lagged behind . Whether the latter will catch up later and physical/social improvements will be maintained is the subject of further studies
