Can allergies trigger asthma?

ANSWER

Allergies are a common problem: 80% of people with asthma have allergies to airborne substances such as tree, grass, and weed pollens, mold, animal dander, dust mites, and cockroach particles. In one study, children who had high levels of cockroach droppings in their homes were four times more likely to have childhood asthma.
