Do Cockroaches Cause Asthma?
WouterAlthough cockroaches themselves do not cause asthma attacks, they may trigger allergic reactions in some people. Allergens from cockroaches are kicked up into the air during routine cleaning and even when you move around. These allergens can trigger an asthma attack, so it’s important to avoid cockroaches if you have a history of asthma.
In a meta-analysis study of research conducted from 2000 to 2013, researchers found a link between indoor cockroach allergen exposure and asthma. Children who were sensitized to cockroach allergens experienced a higher incidence of asthma attacks, especially in inner-city locations. Moreover, children with a positive skin test for cockroach allergens had a 3.4-fold higher risk of hospitalization due to asthma than those who were not exposed to cockroach allergens.
Cockroach allergens and environmental pollutants can cause damage to airway epithelial cells, which release inflammatory factors and cytokines. This is why some researchers believe that environmental pollution can exacerbate allergic sensitization. But the precise molecular mechanism is still unclear.
Cockroach allergies can be very serious and even fatal, and many people are allergic to cockroaches. The most common symptoms of cockroach allergies are watery eyes, runny nose and hives. A doctor will perform a skin test to determine if you’re allergic to cockroach allergens. If your skin test shows positive for cockroach allergens, you may need to take a course of treatment.
