App-technology to Improve the Level of Physical Activity After Bariatric Surgery

App-technology to Increase Physical Activity After Bariatric Surgery: A Randomized Controlled Trial

The aim of this study is to investigate the effect of using new app-based technology to increase the level of physical activity, compared to conventional postoperative information given to patients undergoing bariatric surgery. The hypothesis is that the intervention, i.e. using the new technology, will have a greater positive effect on levels of physical activity and outcomes of weight loss than conventional postoperative information.
