Impact of Bariatric Surgery on Cardiorespiratory Function

Read time: 1 mins
Last updated:25th Jun 2014

Obesity is a growing problem worldwide and its prevention has become one of the leading priorities for the World Health Organisation. Obesity results from chronic imbalance between energy intake and energy expenditure. Although early prevention of obesity is preferable, surgical treatment is often required for severely obese people.

Bariatric surgery has been shown to be the most effective therapy for severe obesity. Weight loss following bariatric surgery results in significant improvements in coexisting comorbidities, such as diabetes and hypertension but there is controversy whether bariatric surgery also improves aerobic capacity.

The purpose of this study is to investigate the effects of bariatric surgery on cardiopulmonary function and on daily physical activity. It is hypothesized that bariatric surgery will improve aerobic capacity and result in beneficial lifestyle changes from sedentary to more active.
