Study summary

The aim of this study was to assess the efficiency of aerobic physical exercise (APE) on weight loss, body composition and co-morbidities in patients after laparoscopic Roux-en-Y Gastric bypass (RYGBP).

Read the detailed description

The only effective treatment for patients with morbid obesity is bariatric surgery. Sudden weight loss following bariatric operations for morbid obesity, such as Roux-en-Y gastric bypass (RYGBP) can result in a concurrent decrease in lean body mass. However the long-time results (weight reduction, elimination co-morbidities) are depending on the post operative treatment. Aerobic physical exercising (APE) is well accepted in conservative treatment of obesity as well as of diabetes mellitus type 2 (DM). The aim of this study was to assess the efficiency of APE on weight loss, body composition and co-morbidities in patients after laparoscopic Roux-en-Y Gastric bypass (RYGBP).
