Health Desk- Oct 18,
2019: Australian researchers analysed lung samples from 52 people and found
the amount of fat increased in line with body mass index.
They said their findings could explain why being overweight
or obese increased asthma risk.
Lung experts said it would be interesting to see if the
effect could be reversed by weight loss.
In the study, published in the European Respiratory Journal,
scientists looked at post-mortem samples of lung donated for research.
Fifteen had had no reported asthma, 21 had asthma but died
of other causes and 16 died of the condition.
The scientists used dyes to carry out detailed analyses of
almost 1,400 airways from the lung samples under the microscope.
The researchers found adipose (fatty) tissue in the walls of
airways, with more present in people with a higher body mass index,
And they say the increase in fat appears to alter the normal
structure of the airways and cause inflammation in the lungs - which could
explain the increased risk of asthma in overweight or obese people.
