Allergies are a common cause of nasal obstruction—in fact, 1 in 5 Americans suffer from them. Unfortunately, nasal allergies cannot be solved surgically, though they can be treated with medications. Left unmanaged, allergies can cause severe nasal mucosa inflammation and inferior turbinate hypertrophy, both of which can cause nasal obstruction. If Dr. Dugar determines that you don’t have anatomical issues that lead to nasal obstruction, he will provide options for medical allergy management instead.
