Musculoskeletal function following bariatric surgery.
OBJECTIVE Bariatric surgery is an effective method for acute weight loss . While the impact of bariatric surgery on general medical conditions ( e.g. , type 2 diabetes ) is well documented , few studies focus on physical functional outcomes following weight-loss induced by bariatric surgery . DESIGN AND METHODS We report on 50 women aged 20 - 74 scheduled for Roux-en-Y gastric bypass ( RYGB ) procedure who were enrolled for a prospect i ve 1-year study . Height , weight , and waist circumference were recorded preoperatively and at 6 and 12 months , postoperatively . To track musculoskeletal/physical function changes , the  timed-get-up- and -go ( TGUG ) and short-form health survey-36 ( SF-36 ) and short musculoskeletal function assessment ( SFMA ) question naires were administered . RESULTS Patients had significant weight loss and functional improvement . At 1 year mean weight loss was 48.5 kg and mean TGUG improvement was 3.1 s. SMFA and SF-36 also showed improvement in functional components with weight loss at 6 months and 1-year post surgery . Significant associations were observed between TGUG and SMFA measures at all time points . Final weight at 1 year post bariatric surgery was also significantly correlated with most functional outcomes and changes in these outcomes . Partial correlations controlling for age revealed additional associations between body weight and functional outcomes , especially at the 6-month visit . CONCLUSION Our results suggest that significant rapid weight loss , such as that attained by bariatric surgery , acutely improves musculoskeletal function in morbidly obese patients . Additionally , for patients with musculoskeletal disease or injury , weight loss result ing from bariatric surgery may serve as an adjunct for improving global functional outcome , and enhancing the rehabilitation potential
