Patient's question:

Type of allergic reaction: Asthma. What kind of help is needed: What is the cause of the allergic reaction?Doctor's answer:
Allergic bronchial asthma is a type of asthma caused by the immune system's hypersensitivity reaction, leading to severe airway narrowing. We refer to this hypersensitivity reaction as allergy. Inhaled substances such as cold air, pollen, and dust mites are the main allergens that trigger it. Certain allergenic foods and medications can also cause allergic reactions. Allergic bronchial asthma is a chronic airway inflammation involving various cells, particularly mast cells, eosinophils, and T lymphocytes. In susceptible individuals, this inflammation can lead to recurrent symptoms such as wheezing, shortness of breath, chest tightness, or coughing, often occurring at night and early morning. The airways exhibit heightened responsiveness to multiple triggering factors.
