Can Inhaled Pollens Cause Intestinal Symptoms?
Allergies to certain foods are more common in individuals with respiratory allergic reactions to airborne pollens. In some cases, gastrointestinal (GI) symptoms do occur. Why and how this happens has been puzzling researchers for some time. But interactions between allergic reactions in the respiratory tract and the GI system are still poorly understood.
The researchers suggest that inhaling pollen allergens led to a systemic reaction involving both the GI tract and the respiratory system, and that there is an immunological interplay between the two. More investigation is warranted.
