What are some possible causes of excessive nasal build up?

* Allergies: Allergies are a common cause of excessive nasal buildup. When you come into contact with an allergen, such as pollen, dust, or pet dander, your body produces histamine. Histamine causes the blood vessels in your nose to swell and produce mucus.

* Colds and flu: Colds and flu can also cause excessive nasal buildup. These viruses can cause the mucous membranes in your nose to become inflamed and swollen, leading to increased mucus production.

* Sinusitis: Sinusitis is an inflammation of the sinuses, which are located around your nose. Sinusitis can cause excessive nasal buildup, as well as other symptoms such as facial pain, headache, and fever.

* Nasal polyps: Nasal polyps are small, non-cancerous growths that can form in the nose. Nasal polyps can block the nasal passages and lead to excessive nasal buildup.

* Deviated septum: A deviated septum is a condition in which the nasal septum, which is the cartilage and bone that separates the two nostrils, is off-center. A deviated septum can cause nasal obstruction and excessive nasal buildup.

* Other medical conditions: Some other medical conditions, such as cystic fibrosis, thyroid problems, and certain medications, can also cause excessive nasal buildup.
