adipose tissue has been found in the Lungs of overweight and obese people for the First Time .

Australian researchers analyzed lung samples from 52 people and found the amount of fat increases, in accordance with the body mass index.

you said their findings could explain why being overweight or obese increases the risk of asthma.

Lungs -the experts said, it would be interesting to see whether the effect could be reversed by weight loss.

Increased risk

In the study, published in the European Respiratory Journal, scientists at the post-mortem samples of Lungs donated for research.

five of the ten had no reported asthma, 21 asthma suffered, but died of other causes, and 16 died of the disease.

The Scientists used dyes to carry out detailed analyses of nearly 1,400 Airways from the lung samples under the microscope.

The researchers found out, adipose tissue (fat) tissue in the walls of the respiratory tract, with more in the presence of people with a higher body mass index,

" And you say that the increase in fat is shown to change the normal structure of the respiratory tract and cause inflammation in the Lungs , which could explain the increased risk of asthma in overweight or obese people.

Direct printing

Dr. Peter Noble , associate professor at the University of Western Australia in Perth, worked on the study, said: "overweight or obesity has already been associated with asthma or asthma symptoms worse.

"have suggested to researchers that The Link could be explained by the direct pressure of excess weight on the Lungs or by a General increase in inflammation created by excess weight. "

But he said their study suggested, "a further mechanism is also in the game".

"We have found that the excess fat accumulates in the respiratory tract walls, where it takes place and to increase seems to be inflammation in the Lungs ," Dr. Noble said.

"We think this is causing a thickening of the airway limits the flow of air in and out of the Lungs and this could explain, at least partially, an increase in asthma symptoms. "

'Great importance'

Prof Thierry Troosters, President of the European Respiratory Society, said: "This is an important finding about The Relationship between body weight and disease of the respiratory tract, because it shows how being overweight or obese could be making the symptoms worse for people with asthma.

"this goes beyond the simple observation that patients with obesity, to breathe more, with activity and movement.

"The view points of the true respiratory changes associated with obesity. "

He said more research was needed to determine whether this accumulation of the adipose tissue could be reversed by weight loss, but the asthma patients should be helped to reach a healthy weight.

Dr. Elizabeth Sapey, Chairman of the science Committee of The British Thoracic Society, said this had been shown for the First Time the weight of the body to influence the structure of the Airways in the Lungs .

"in view of the increasing incidence of obesity nationally and across the world, the study could understand helps of great importance in the us, why asthma remains a major health Problem and identify new ways to improve the treatment of asthma," She Said .

"It was only a small study, though, and we need to verify this in larger groups of patients and other lung diseases," Dr. Sapey added.
