Pet Allergies Worsen Hay Fever Symptoms
Being allergic to dogs or cats may worsen your ragweed allergies, according to a study from Queen's University.
Researchers found that people with pet allergies often develop ragweed allergy symptoms more quickly than others. But the study also suggests that once allergy season is in full swing, those symptom differences subside.
"The study results helped us develop a theory of 'pre-priming'," says Dr. Ellis. "If you have ongoing symptoms from perennial allergies, as soon as you add another allergen into the mix your symptoms develop much faster, and you may have a harder time dealing with it than others."
Dr. Ellis says that ideally patients with animal allergies should find alternative homes for their pets, or at least minimize their exposure by not allowing animals access to the bedroom of the allergic individual. This becomes even more important in the case of children suffering from asthma, and could prevent the development of irreversible lung damage due to ongoing allergic inflammation.
