Checking and Treating Coughing and Wheezing in a 3-Year-9-Month-Old Child

Question

A 3-year-9-month-old child has been suffering from chronic cough accompanied by wheezing, with symptoms including dry cough at night and phlegm sounds in the morning, with varying cough frequency throughout the year. What tests should be done to determine the cause?

Answer

To determine the cause, it is recommended to undergo examinations including chest X-rays, CT scans, bronchoscopy, and bronchial provocation tests. Treatment may require oral antibiotics, corticosteroids, cough suppressants, and expectorants. In daily life, it is advisable to avoid spicy, cold, and other irritating foods and to enhance physical fitness through exercise. If conservative treatment is ineffective, it may be necessary to consider nasal endoscopy or sinus surgery.
