What Causes Asthma?
Asthma is caused by a combination of genetic and environmental factors that lead to the inflammation and narrowing of the airways. In individuals with a genetic predisposition to asthma, the immune system overreacts to certain triggers such as allergens, pollutants, or respiratory infections. When exposed to these triggers, the body’s immune response causes the airways to become inflamed, resulting in asthma symptoms. Environmental factors such as exposure to tobacco smoke, air pollution, or allergens like dust mites and pet dander can increase the risk of developing asthma or exacerbate existing asthma symptoms.
While asthma is often inherited, it can also develop in individuals who are exposed to certain environmental factors. Early childhood exposure to allergens or respiratory infections is believed to play a role in the development of asthma, particularly in children who are genetically predisposed. Additionally, some individuals develop asthma due to occupational exposures, such as working with chemicals or dust. Understanding the causes of asthma helps with prevention, identification of triggers, and appropriate management strategies.
