What is nasal obstruction and do I have it?

Almost everyone experiences some sort of nasal congestion at some time throughout the night while sleeping. Some of the most common causes of nasal obstruction or a “stuffy nose” are chronic or acute sinusitis, allergic rhinitis, and environmental conditions such as seasonal allergies, smoke or atmosphere irritants (dust or dirt). The common cold, flu, alcohol and certain medications such as blood pressure medications, can lead to dryness and congestion also. Some people have anatomical conditions that can also lead to nasal congestion or resistance, such as a deviated septum or nasal polyps. Nasal congestion is important to recognize because it can influence how effective your therapy will be for the treatment of OSA.
