What Is Asthma

Asthma is a lung disease that is caused by chronic inflammation of the airways. It is one of the most common diseases of children. Asthma is most common in children but, adults can have asthma, too. Asthma attacks occur when lung airways become swollen and tighten due to airway inflammation. Asthma attacks can be caused by airway infection, allergy particles, chemical irritants, and air pollution.


During an asthma attack, people with asthma experience symptoms such as wheezing, breathlessness, chest tightness, and nighttime or early morning coughing.

How is asthma treated?

Asthma can be treated with medicine. Not everyone takes the same medicine. Some medicines can be inhaled, or breathed in, and some can be taken as a pill. Asthma medicines come in two types, quick relief and long term control. Some medicines have side effects, but most effects are mild and go away quickly.

How is asthma contracted?

Asthma is not a contagious disease. Asthma is a chronic disease and is not spread from person to person. The development of asthma is likely due to a combination of genetic and environmental factors.
