In a first of its kind study, researchers detected major fat tissue accumulation in the airway walls of overweight and obese people. The study suggests that this accumulation of fats could probably explain why obese individuals stand at an increased risk of asthma and respiratory disease.
Previously, being obese or overweight has already been associated with asthma or worse symptoms of asthma, says study co-author, Peter Noble from University of Western Australia.
The study hypothesized an association between excessive fatty tissues present within the airway walls of a person, respiratory disease and their body weight. The researchers studied post-mortem lung samples of 52 subjects and discovered a direct relation between increasing fatty tissue and body weight in the airways of a person.
According to the researchers, excess fat gets accumulated in a person’s airways, consuming space and increasing inflammation within lungs. They believe that this results in thickening of airway walls which in turn limits air flow in the lungs. This could partly explain the increase in asthma symptoms.
As the study was not conducted on an extensive scale, more research is required to understand the relevance of these respiratory diseases to fatty accumulations. But, the findings of this study are still fascinating.
