How to diagnose and differentiate postnasal drip syndrome

summary

Postnasal drip syndrome (PNDs) refers to nasal diseases that cause secretion to flow back to the back of the nose and throat, or even into the glottis or trachea. Leading to cough or allergic rhinitis in patients with nasal inflammatory secretions can flow into or inhale into the lungs through the posterior nostril and throat, the main manifestation of the syndrome. If a patient has postnasal drip syndrome, for example, if he accidentally swallows it during a meal, the food will be sucked into the postnasal position. Let's take a look at the following.

How to diagnose and differentiate postnasal drip syndrome

First: when sleeping in supine position, nasal inflammatory secretions unknowingly flow into the airway, which may be an important reason for the development of allergic rhinitis into asthma. The change of breathing pattern is also one of the factors that cause allergic rhinitis and asthma. Because of * swelling of nasal mucosa, hypertrophy of turbinates and retention of secretions, nasal congestion can be caused.

Second: most of the patients have nasal secretions after flow, oral mucus adhesion, throat itching, foreign body feeling or "paste adhesion throat" feeling, and frequent throat cleaning. In short, it is because of nasal reflux caused by pharyngeal discomfort, people will naturally have a reflex cough.

Third: postnasal drip syndrome is easy to be missed and misdiagnosed in clinic. The main reason is that doctors lack the understanding of postnasal drip syndrome. They only pay attention to the performance of tonsil, pharynx and lung. When they see the thick and deep texture of chest film, they can diagnose interstitial pneumonia, but ignore the patient's history and other signs.
