Although
allergies and asthma produce different symptoms, they are often
triggered by the same substances. James Li, M.D., an allergy
specialist at Mayo Clinic states that “nearly all
children with asthma—and up to half of adults with asthma—also
have allergies.”
An
allergy is an extreme sensitivity to a substance. The major
difference between allergies and asthma is that allergies encompass
a much broader set of sensitivities, while asthma is a chronic
respiratory disease that causes air passages to become narrow or
blocked, making breathing difficult.
Asthma symptoms can be triggered by allergies, exercise, emotional
stress, airborne irritants and odors, animal dander, gastroesophageal
reflux (GERD) the common cold and more. While all cases of asthma
are not due to allergies, a significant percentage is due to allergens,
particularly the airborne allergens.
