A study published in Infection and Immunity reports that the risk of developing chronic asthma or allergies can be caused by changes in the microflora of the gastrointestinal tract. Researchers believe that the bacteria and fungi lining the tract prevent the immune system from responding to inhaled allergens. Disruptions of this microflora can reduce tolerance and hence increase sensitization. Thus, changes to microflora may be considered a risk factor for developing asthma and allergies. Many researchers however, believe that the lungs are responsible for developing this tolerance to allergens.
