Gaining weight in later years has a detrimental impact on lung health, a new study suggests.
People’s lungs naturally deteriorate as they age and lose functionality as the years go by. But now new research has linked moderate or significant weight gain to an even sharper decline in lung health.
According to the study of 3,700 individuals in Europe and Australia, who were recruited between the ages of 20 and 44, and were studied for 20 years, people who gained weight throughout the course of the study – regardless of whether they were a healthy weight or overweight/obese to begin with – had accelerated lung function decline.
Furthermore, overweight/obese individuals who lost weight during the study saw their lung functionality decline slow.
Publishing their findings in the journal Thorax, the researchers said large amounts of fat in the abdomen and chest can limit the space lungs have when people inhale. It was also suggested that fat produces inflammatory chemicals that can reduce the diameter of airways and damage lungs.
Speaking about the findings of the research, study leader Judith Garcia Aymerich, head of the non-communicable diseases and environment program at Barcelona Institute for Global Health (ISGlobal), said: “Although previous research has shown that weight gain is linked to lung function decline, ours is the first study to analyze such a varied population sample over a longer period of time.”
