Kirk P. Withrow, MD, shares some causes and solutions to snoring.

While the nose generally is not the direct source of the tissue vibration, nasal obstruction – like that from congestion due to cold or allergy – can play a role in snoring. This contributes to snoring due primarily to the change in position of the structures in the throat that occurs with mouth breathing, namely displacement of the tissue toward the back wall of the throat.

“Alleviating nasal obstruction and transitioning away from mouth breathing can improve or eliminate snoring,” Withrow said. “Such treatment can include allergy management or surgery to correct structural defects in the nose.”
