Optimizing lifestyle interventions in adult patients with comorbid asthma and obesity

The prevalence of obesity and asthma are both increasing at alarming rates. The link between obesity and asthma suggests that obesity contributes to both risk of new onset asthma and increased asthma severity. The emerging evidence demonstrating the role of obesity and other lifestyle factors, such as diet and physical activity, on asthma outcomes warrants lifestyle interventions that can address these components of asthma care. This review examines the current literature on the pathophysiology of obesity's role in asthma, as well as the role of diet and physical activity in weight loss and in asthma outcomes. We discuss recent studies that employ lifestyle interventions to target improved asthma outcomes. Finally, we discuss the future direction of research in this area.
