What is environmentally induced asthma?

Environmental triggers include exercise, hyperventilation, hormonal changes, and emotional upset, airborne pollutants, as well as GERD. Environmental pollutants may affect asthma severity it might act as a trigger leading to an asthma exacerbation. The pollutant can exacerbate a pre-existing airway inflammation.

Is asthma an environmental health issue?

Asthma affects people of all races, sexes, and ages across every region of the U.S. Asthma can be triggered by substances in the environment called allergens. Indoor allergens from dust mites, cockroaches, dogs, cats, rodents and molds are among the most important environmental triggers for asthma.

Asthma is caused by an overreaction from the immune system to certain triggers. This is similar to a class of diseases caused by an immune system response. These are called autoimmune conditions. However, asthma is not considered an autoimmune disease.

What mutations cause asthma?

“In this study we found that a mutation in the YKL-40 gene is associated with YKL-40 levels in the blood, a diagnosis of asthma, and impaired lung function. Ultimately, blocking the effects of YKL-40 may prove to be a novel and effective way to treat asthma.”
