In an abbreviated form, Post Nasal Drip is also called PND. Post Nasal Drip is a condition where the nasal mucosa (mucous lining in the nasal cavity) releases access mucous, which if not expelled accumulates in the back of the nose or throat. The presence of mucus in abundance causes a feeling of dripping down the back of the throat, congestion in the throat, itching of the throat, coughing, and a constant need to clear the throat.
Nasal mucosa releases mucus to keep nasal cavities moist to trap foreign particles like dust, pollen and any other foreign matter. When foreign particles are not filtered through the nose and enters into the respiratory system they can cause severe respiratory problems. Mucus assists in combating such respiratory problems but when excess nasal mucosa is released it is called Post Nasal Drip or Upper Airway Cough Syndrome.
The accumulation of mucus in the back of the throat and nose may also cause swelling and bleeding in the nose (nasal cavity). A person suffering from Post Nasal Drip often feels the need to drain the excess mucus, which feels like they have a cold, but in fact, this is not cold.
Symptoms of Post Nasal Drip may include the following:
- Excessive Coughing
- A constant need to clear one’s throat
- Halitosis (bad breath)
- An excessively sore throat that is not caused by a cold
- Nausea or vomiting
If Post Nasal Drip is left untreated, it could lead to other more serious conditions such as an ear infection or bronchitis.
A Person suffering from Post Nasal Drip may also complain about having Halitosis (bad breath) due to mucus being high in protein. Bad breath can be easily treated if it is caused by Post Nasal Drip. By controlling mucus production, bad breath is eliminated.
