Question
Why do young children have difficulties with persistent cough?
Answer
Persistent cough in young children can be caused by a variety of factors, including allergic cough and asthma. The clinical characteristics of allergic cough are chronic cough without a cause for less than two months, with paroxysmal, stimulating (irritating) mild coughs, or a very small amount of whitish frothy sputum. It may become more tolerable when exposed to smoke, fumes, or chemical odors like paint. Multiple different antibiotics have been ineffective, and detailed imaging with X-rays or CT scans show no obvious abnormalities. 40% of patients may also experience symptoms of allergic rhinitis such as hiccups and runny nose. The treatment for asthma is similar to the management of asthma attacks, with the principle of removing the cause, preventing recurrence, and taking preventive measures. The causes of asthma are complex, influenced by both genetic factors from previous generations and environmental interference. It is important to avoid contact with allergens, actively treat and thoroughly clear infectious foci, eliminate various triggering factors such as smoking, paint, cold drinks, and dramatic changes in weather. During asthma exacerbations, medication can be used to relax bronchial smooth muscle spasm, reduce mucosal edema and inflammation in the airways, and increase mucus excretion.
