Physical activity and its association with psychosocial health following bariatric surgery.

Physical activity (PA) helps sustain weight loss and may also provide psychological benefits in patients undergoing bariatric surgery. Using a set of questionnaires, we demonstrated that bariatric patients with increased level of PA at 1-year follow-up had better psychosocial outcomes including depressive symptoms and mental health-related quality of life compared with those who had reduced or unchanged level of PA. Our findings indicate the benefit of incorporating PA in the postoperative care for bariatric patients. Postoperative behavioural change in terms of physical activity improves psychosocial health in patients undergoing bariatric surgery.
