How is phlegm cough to return a responsibility?

First: cough with phlegm is caused by a cold attack, which is one of the common causes of chronic cough in patients, especially preschool and school-age patients. The clinical features are as follows: (1) cough lasts for more than 4 weeks, often occurs at night and (or) in the morning, cough aggravates after exercise and cold air, and there is no sign of infection or no response to antibiotic treatment for a long time（ 2) Bronchodilator can relieve cough symptoms（ 3) Pulmonary function test showed airway hyperresponsiveness（ 4) A history of allergic diseases and positive allergen test can assist in the diagnosis. The treatment principle is the same as that of typical bronchial asthma.

Second: a variety of rhinitis, sinusitis, chronic pharyngitis, chronic tonsillitis, nasal polyps, adenoid hypertrophy and other upper airway diseases can cause chronic cough, previously diagnosed as postnasal drip (flow) syndrome, which means cough caused by nasal secretions flowing back to the pharynx through the postnasal orifice. The clinical features are as follows: (1) chronic cough with or without expectoration, especially in the morning or when the body position changes, often accompanied by nasal congestion, runny nose, dry throat, foreign body sensation, repeated throat cleaning, and mucus adhesion on the posterior pharyngeal wall（ 2) There may be tenderness in the paranasal sinus area, yellow and white secretions may flow out at the opening of the paranasal sinus, obvious hyperplasia of posterior pharyngeal wall follicles, cobblestone like, and sometimes mucus like attachment can be seen in the posterior pharyngeal wall. The key point of treatment is to treat upper airway lesions, cough symptoms can disappear.

When there is inflammation in the respiratory tract, increased secretion or foreign body, it is beneficial to the recovery of the body by coughing up the secretion. Blind antitussive is harmful and unhelpful. Patients cough, most of which are caused by respiratory tract infection, the most common are cold and bronchitis.
