Diagnosis
Diagnosis and identification of postnasal drip syndrome
In particular, intranasal inflammatory secretions in the supine position sleep into the airway unconsciously, and it is very likely that allergic rhinitis develops into an important cause of asthma (especially nocturnal asthma). Changes in breathing patterns are also one of the factors that are closely related to allergic rhinitis and asthma. Due to swelling of the nasal mucosa, hypertrophy of the turbinate and retention of secretions, nasal congestion can be caused, and patients are forced to change from nasal breathing to mouth breathing. Mainly, allergens can bypass the nasal mucosal barrier and directly enter the lower respiratory tract to cause asthma. Postnasal drip syndrome is the most common cause of chronic cough in adults and is the second most common cause of chronic cough in children. Postnasal drip syndrome is clinically easy to miss diagnosis and misdiagnosis. The main reason is that the physician lacks understanding of postnasal drip syndrome, only pay attention to the performance of tonsils, pharynx and lungs, and see the texture of chest radiograph is diagnosed as interstitial pneumonia. While ignoring the patient's medical history and other signs. In fact, postnasal drip syndrome is the most common cause of chronic cough. Patients with chronic cough can be given specific experience in the treatment of postnasal drip syndrome before the cause is determined, and the disease is diagnosed according to the curative effect.
