Overweight people more likely to get asthma

Posted by AregM

Obese and overweight people are 50 percent more likely to get asthma than those of normal weight, suggesting that weight loss could help reduce the number of asthma cases, U.S. researchers said Monday. Asthma, an inflammatory disease usually triggered by an allergy, can cause wheezing, coughing and labored breathing that can be life-threatening. It affects about 7 percent of the U.S. adult population. Obesity and being overweight are far more prevalent, affecting about 65 percent of U.S. adults. Both types of ailments are on the rise and a new study suggests the two may be linked. "Overweight and obesity significantly increases the risk of developing asthma," said Dr. E. Rand Sutherland of the National Jewish Medical and Research Center in Denver, Colorado, who wrote the study. "If you can substantially reduce the amount of overweight or obese people, you might also get a reduction in the number of new cases of asthma," Sutherland said in a telephone interview. Sutherland and colleagues, writing in the April issue of the American Journal of Respiratory and Critical Care Medicine, said a significant reduction in the incidence of overweight or obese people could cut the number of new asthma cases in the United States by 250,000 per year. In children, where the incidence of asthma is five times higher than in adults, the researchers suggested that even small weight reductions could have a big impact in reducing the number of new asthma diagnoses. Sutherland said the study gives another reason to develop effective treatments for excess weight, which can cause diabetes, high blood pressure and certain cancers. The researchers looked at seven studies on severe asthma involving 333,102 patients. People in the studies either had a doctor's diagnosis of asthma or were taking asthma medication. ....Continued on
