What triggers asthma, leading to difficulty in breathing?

Allergies are a significant trigger for asthma, leading to difficulty in breathing. When an individual with asthma encounters allergens, such as pollen, dust mites, mold, or pet dander, their immune system can overreact. This overreaction causes inflammation in the airways, airway constriction, and increased mucus production, all of which contribute to the characteristic symptoms of asthma, including wheezing, shortness of breath, and coughing.

While exercise, rhinitis, and sinusitis can also influence asthma symptoms or can coexist with asthma, allergies are particularly noted for initiating acute asthma episodes in susceptible individuals. Understanding that allergies can provoke an asthma attack helps patients and healthcare providers to identify and avoid specific triggers, ultimately improving asthma management and control.
