What is Post Nasal Drip ?
- 10 years agoFavorite Answer
If you've ever had a particularly nasty bit of phlegm in the back of your throat, you've experienced post-nasal drip. Think of it like a runny nose in the back of your throat. The nose and throat normally house mucous. Mucous traps bacteria and keeps unwanted debris out, serving an important function in immunity. Excess mucous is swallowed unconsciously most of the time, but when conditions such as a cold or flu arise, the fluidity of mucous can change and cause build up or excessively thin secretions. Here are some conditions that can affect post-nasal drip:
* eating spicy foods
* birth control and high blood pressure medications
* structural abnormalities, such as deviated septum or enlarged turbines
* dry air
* eating a lot of dairy productsSource(s): http://ent.about.com/
