Asthma and Obesity: are they linked?

Research has suggested that there is a link between obesity and asthma. A US study indicates that the increase in childhood asthma may be linked to an increase in obesity. The researchers suggest that obesity decreases the capacity of the airway muscles to stretch resulting in narrowing of the airway and difficulty in breathing. This narrowing also makes the airway more sensitive to other asthma triggers.

Still another study done by Harvard Medical School has found that obese people are 3 times more at risk of developing asthma as compared to those with normal weight. Infact, among children who were overweight or obese, the risk of developing asthma was increased by 52% and 60%, respectively. Hence, appropriate strategies for the reduction of body weight in children may contribute to a reduced incidence of asthma in children. However some more studies are being done to support these findings.
