Causes Of Post Nasal Drip

Our nose helps us not only to smell the food we eat but also helps to enhance our eating experience. It also warms, cleanses and humidifies the air we suck into our lungs so we can breathe easier. Our nose normally produces around 2 liters of mucus which helps in cleaning the respiratory tract and keeping it moist. Post-nasal drip is the accumulation of mucus in the back of the nose and throat which gives way to the sensation of dripping mucus. Such condition may lead to chronic cough or chronic sore throat. One of the causes of post nasal drip is excessive mucus secretions. It can also be caused the failure of the mucus to be cleared from our nose and throat.
Excessive thin mucus secretions can be caused by cold temperatures, viruses, and allergies. Certain foods, changes in the hormone levels, and certain drugs can also cause the nose to produce too much mucus. On the other hand, excessive thick secretions can be caused by low a sinus or nasal infection, tobacco smoke, and low humidity among others.
Some conditions that can cause the failure of the mucus secretions to be cleared from the nose and the throat are swallowing problems which can be aggravated by stress, gastroesophageal reflux (GERD), advancing age, and muscle or nerve disorders.
Since post-nasal drip is caused by an underlying condition, treatment usually involves identifying the underlying condition and correcting it accordingly. If it is caused by allergies for example, you must identify and avoid your known allergens such as pollen, animal dander, house dust, pollen, some foods, and dust mites. It can be very difficult to identify and avoid which particular allergen is affecting you. You can prevent allergies by using a pollen mask when you are cleaning your house or mowing your garden, changing the air filter in your air conditioner or heater, installing an air purifier unit and keeping your windows closed during known high pollen periods.
