Possible causes of increased nasal mucus?

The increased nasal mucus occurs once the tissues that line the sinuses or nose are irritated or swollen. Bacterial or viral infections, environmental irritants, allergies and nasal polyps are among the common causes of runny nose which is also called as rhinitis. The treatment measures to alleviate this condition tend to vary, depending on the underlying causes.

In case the increased nasal mucus production is affecting the individual, it is best to consult a doctor as soon as possible for proper assessment as well as provide the appropriate treatment option.


Nasal mucus

Bacterial or viral infections, environmental irritants, allergies and nasal polyps are among the common causes of runny nose which is also called as rhinitis.

It is important to note that a runny nose initiated by an allergy is called as allergic rhinitis. The immune system responds to different types of inhaled particles which results to swelling of the nasal tissues as well as increased nasal mucus. Itchy eyes, sneezing and excessive tear production are also present during an episode of allergic rhinitis.

The usual triggers of allergic rhinitis include plant and tree pollen, mold, pet dander, cigarette smoke, insect droppings, fragrances and dust mites. Take note that allergic rhinitis can occur all year or seasonal depending on the triggers.

Upper respiratory infections

Upper respiratory infections have been the common cause of runny nose among many individuals all over the world. Bacterial or viral sinusitis is also a known cause for the increased nasal mucus. Chickenpox, influenza, measles, whooping cough and rubella usually cause upper respiratory symptoms including runny nose.

Environmental triggers

The inhalation of potential environmental irritants can trigger the inflammation of the nasal tissues, thus leading to increased nasal mucus and a runny nose. This is a condition called as non-allergic rhinitis. Take note that this form of rhinitis usually occurs among adults. Pollution, smoke and strong odors are responsible for instigating non-allergic rhinitis among highly susceptible individuals.

There are also certain medications that can cause non-allergic rhinitis which includes non-steroidal anti-inflammatory drugs, beta-blockers, sedatives, antidepressants and birth control pills. The extended usage of nasal decongestant sprays can also lead to rebound rhinitis once the medication is stopped.

Nasal polyps

Nasal polyps are described as small-size growths on the tissue lining in the sinuses and the nose. These are non-cancerous growths that are capable of causing runny nose, postnasal drip, nasal stuffiness, diminished sense of smell and taste as well as blocked airflow. Even though there is no identifiable cause that can be determined in most cases of nasal polyps, those who have asthma or allergy to aspirin are prone to develop them.
