Description
Summary:Obesity is associated with increased severity of asthma. Bariatric surgery can be effective in weight loss and improvement in asthma. Two reviewers conducted a systematic review using search terms: ‘weight loss’, ‘bariatric surgery’, and ‘asthma’. Adult studies including all bariatric procedures and nonsurgical weight loss regimes were included. Thirty-nine studies, including twenty-six bariatric studies and thirteen nonsurgical studies, were found. No study directly compared bariatric surgery to nonsurgical techniques. Bariatric surgery offered greater weight loss (22–36%) than nonsurgical programmes (4.1–14.2%) and more consistently improved medication use, airway hyperresponsiveness, hospitalisation rate or ED attendance and lung function, while change in inflammatory markers were variable. Bariatric surgery appears to be superior in treating asthma; however, further study on surgery for both mild and severe asthma is required.
