Obesity alters airway muscle function, increases asthma risk: Study suggests asthma in obesity related to airway narrowing rather than inflammation
New research suggests that obesity changes how airway muscles function, increasing the risk of developing asthma. The study is published ahead of print in the American Journal of Physiology - Lung Cellular and Molecular Physiology. The prevalence of asthma and obesity - as both separate and coexisting conditions - has grown considerably in the US in recent years. Hyperresponsiveness causes the airways to narrow, obstructing ease of breathing, and can occur when the muscles contract or begin to spasm.
