Asthma is a single disease state where there is inflammation of the airways and reversible obstruction. However, it is often called different things. Names for types of asthma can describe the triggers that cause an asthma episode or the things that make asthma worse in certain individuals.

Exercise-Induced Asthma
Exercise commonly makes asthma symptoms worse. With treatment and monitoring, people with exercise-induced asthma can continue to participate in physical activities. The more inflamed the airways are, the less exercise it takes to cause symptoms. Learn more about exercise-induced asthma.

Nocturnal Asthma
Worsening of asthma at night is very common and treatment of underlying causes can help greatly. As with exercise, when asthma is a problem at night, it usually means that the inflammation in the airways is worse. Learn more about nocturnal asthma.

Occupational Asthma
Workplace exposure to certain chemicals or dusts can induce asthma. These exposures can cause an allergic type of reaction or be an irritant to the airways. Quick recognition and control of workplace exposures is important. Learn more about occupational asthma.

Steroid-Resistant Asthma (Severe Asthma)
While the majority of patients respond to regular inhaled glucocorticoid (steroid) therapy, some people are steroid resistant. These people do not respond to steroids at normal doses. Speak with your healthcare provider about an action plan for working with this type of asthma.

Allergic Asthma
Allergies can make asthma symptoms worse. So it is best to avoid the things to which you are allergic. Learn more about allergic asthma and how to avoid allergens.
