It is a common misunderstanding that nasal congestion is the result of excessive mucus. While this can cause nasal congestion, the most common cause of a dry nose with congestion is inflammation in the lining of the sinus cavity that causes swelling and obstruction with breathing, according to the University of Maryland Medical Center. Inflammation in the sinus cavity can result from various conditions without any mucus being produced, such as nasal polyps, allergies and a deviated septum. Make an appointment with a medical doctor for proper diagnosis. Chronic nasal congestion may be a sign of a serious condition.
Nasal Polyps
Nasal polyps are growths in the nose and along the nasal lining that can cause obstruction, leading to a dry nose and congestion, according to the American Rhinologic Society. No one knows what exactly causes nasal polyps, but doctors do know they are related to chronic sinusitis and allergy conditions. Nasal polyps are commonly treated with nasal sprays containing corticosteroids that reduce and prevent inflammation. If corticosteroids do not reduce the size of the polyps, surgery may be a consideration. Nasal polyps can completely block airflow in the nose, creating permanent dry congestion. If nasal polyps go untreated they can cause facial distortion. Talk with an eye, nose and throat specialist if someone suspects he has nasal polyps.
Allergies
Allergies are another common cause of dry nose and congestion, according to MedlinePlus, a publication of the National Institutes of Health. When someone has allergies, the body produces an excessive amount of histamine that leads to irritation in the sinus cavity. The irritation causes the lining in the nasal passages to become inflamed. The inflammation leads to swelling and results in nasal congestion. Allergies are treated by avoiding allergens and the use of over-the-counter medications. Medications used to treat congestion from allergies are decongestants, antihistamines and saline sprays. Decongestants reduce nasal inflammation, antihistamines alleviate allergy symptoms and saline sprays keep the sinus cavity moistened.
Dry Air
Dry air can cause a dry nose with nasal congestion, according to the University of Maryland Medical Center. Dry air can cause the sinuses to become inflamed, cutting off the ability to breathe normally. Use cool mist humidifiers to sooth and moisten the nasal passages. Keep the air moister in the house around 50 percent for optimum sinus health.
Deviated Septum
A deviated septum is a condition in which the center bone of the nose is severely crooked, according to the American Academy of Otolaryngology. Everyone's nasal bone is minimally crooked. When the septum is crooked enough that one nostril appears smaller than the other and the person's breathing is affected, it is treated as a condition. A deviated septum is corrected through nasal surgery.
