The most common type of asthma is allergic asthma. This form of asthma is triggered by exposure to allergens, such as pollen, dust mites, pet dander, mold, and certain foods. The immune system mistakenly identifies these harmless substances as threats, leading to an inflammatory response that can cause symptoms like wheezing, coughing, shortness of breath, and chest tightness.

Allergic asthma tends to be more prevalent than other types because it is linked to the high prevalence of allergens in the environment that many people are exposed to. In addition, those with a family history of allergies or allergic conditions are more likely to develop allergic asthma.

Other types of asthma, such as exercise-induced, non-allergic, and occupational asthma, do occur frequently but are not as commonly diagnosed as allergic asthma. Exercise-induced asthma is specifically associated with physical activity, non-allergic asthma is triggered by irritants and not allergens, and occupational asthma results from specific workplace exposures.
