The symptoms of postnasal drip are chronic inflammation caused by paradoxical or non-paradoxical nasal and sinusitis. The secretions in the inflamed area flow backward from the nasal cavity and enter the throat, causing chronic coughing and a foreign body in the throat due to frequent irritation. There is also the symptom of mucous phlegm feeling in the throat, and this clinical symptom is the main characteristic. These symptoms are related to the following factors.
1. Etiology of postnasal drip. Inflammation of the nasal mucosa leads to a weakened adjustment to temperature and humidity, and a reduced protective effect can occur. The effectiveness of nasal cilia movement and foreign body removal is reduced, resulting in a highly reactive state in the airway. The direction of nasal mucus enters the throat and leads to chronic coughing disorders. Sinusitis and rhinitis, which can lead to inflammatory symptoms, can therefore flow downward from the nasal mucus and cause a cough to appear as a chronic cough disease.
2. Common diseases. The disease of postnasal drip can lead to symptoms often seen in rhinitis, sinusitis, allergic rhinitis, etc.
To treat the symptoms of postnasal drip, it is important to prevent rhinitis, sinusitis, etc. from the root cause. If you have an acute inflammation, you should get treatment in time to prevent it from becoming chronic. The symptoms of postnasal drip need to be taken seriously by parents.
