An abnormal immune response to allergens among people with gastroesophageal reflux disease (GERD) might increase their chances of developing asthma, according to WebMD.
For years, researchers have observed an asthma-GERD association, as studies have shown 50 percent to 90 percent of asthma sufferers also have acid reflux, WebMD reports. Research published in the European Journal of Clinical Investigation explains why this relationship might exist.
The study found that when the lungs of laboratory mice were exposed to gastric fluid, their immune response was similar to that of people with asthma. Therefore, the research suggests that GERD, which can move stomach acid into the lungs and esophagus, could lead to asthma.
To control GERD, the WebMD story recommends smaller meals, a healthy weight and limits on the consumption of fatty foods. Digestive enzyme supplements can also be beneficial in reducing or eliminating the symptoms of indigestion, bloating and other digestive disorders.
