A new study has revealed that being allergic to dogs or cats may worsen your ragweed allergies.
The study has also suggested that once allergy season is in full swing, those symptom differences subside.
The team, led by Anne Ellis of the Queen`s University, exposed 123 participants to ragweed, and noted that pet allergy sufferers reported symptoms differently than their non-animal allergic counterparts.
Dust mite allergic patients also developed symptoms more quickly after ragweed exposure.
"The study results helped us develop a theory of ``pre-priming``."
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," said Ellis.
Ellis said 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.
