FRIDAY, Oct. 18, 2019 (HealthDay News) — Excess weight is hard on the heart, but new research shows it may also harm your lungs.
The findings showed, for the first time, that fatty tissue accumulates in the walls of airways and that the amount of fat in airways increases with body mass index (an estimate of body fat based on weight and height).
The researchers also found that higher levels of fat change the normal structure of airways, resulting in lung inflammation, according to the report published Oct. 17 in the European Respiratory Journal.
“Being overweight or obese has already been linked to having asthma or having worse asthma symptoms. Researchers have suggested that the link might be explained by the direct pressure of excess weight on the lungs or by a general increase in inflammation created by excess weight,” explained study co-author Peter Noble. He’s an associate professor at the University of Western Australia in Perth.
