Bronchial asthma in children

Bronchial asthma, asthma. It is a reversible, obstructive respiratory disease with recurrent cough, wheezing, and dyspnea, accompanied by airway hyperresponsiveness. It is generally believed to be related to allergies, but numerous studies have shown that not all patients with wheezing have clear immunological changes, and conversely, not all patients with allergic diseases develop asthma. Asthma can develop at any age, but most of them start before the age of 4 to 5. Actively preventing and treating bronchial asthma in children is of great significance in preventing and treating bronchial asthma in adults.
