The sensation of nasal congestion may be due to a variety of conditions. A deviated septum is the most common cause of nasal obstruction. Enlarged turbinates is the second most common cause of breathing difficulty, and usually associated with a deviated septum. Other structural problems with the nose, such as small nostrils, weak nostrils, scarring, and a narrow or collapsed nasal valve, may also contribute to nasal obstruction. Many other conditions, such as medication side effects, allergies, irritants, chronic sinusitis, and systemic illnesses, can contribute to nasal breathing problems.
