Bronchial asthma, commonly known as asthma, involves chronic airway inflammation of the bronchi with the participation of various chronic inflammatory cells. Patients primarily exhibit symptoms such as episodic wheezing, breathlessness, chest tightness, and coughing. These symptoms usually occur in the early morning and at night, and can improve on their own or with medication. Generally, the occurrence of bronchial asthma is related to genetic factors and contact with allergens, with most patients having some genetic predisposition. Once bronchial asthma develops, it is advisable to avoid allergens, such as pollen, dust mites, pet dander, etc. Generally speaking, the prognosis for bronchial asthma is very good.
