Airway Anatomy
A narrow throat, enlarged tonsils or adenoids, a low soft palate, or a long uvula can reduce the space airflow needs to move freely — causing tissue vibration during sleep.
Snoring happens when airflow through the nose or throat is partially blocked during sleep, causing soft tissue to vibrate. While occasional snoring is common, loud or chronic snoring can be a sign of obstructive sleep apnea or another breathing condition that deserves attention.
A sleep medicine evaluation can determine whether snoring is an isolated issue or part of a broader condition — and point toward the most effective treatment path.
Snoring often has an identifiable cause. Understanding what is driving the obstruction helps determine the most effective treatment.
A narrow throat, enlarged tonsils or adenoids, a low soft palate, or a long uvula can reduce the space airflow needs to move freely — causing tissue vibration during sleep.
Chronic nasal obstruction from allergies, sinus infections, or a deviated septum forces mouth breathing, which is more likely to produce snoring than nasal breathing.
Back sleeping allows the tongue and soft palate to fall backward and partially block the airway. Many people who snore only do so — or snore more loudly — when lying on their back.
Extra tissue around the neck and throat can narrow the airway and increase the likelihood of snoring, particularly when muscle tone decreases further during sleep.
Alcohol and certain sleep aids relax the muscles of the throat more than normal, reducing the tone needed to keep the airway from partially collapsing during sleep.
Snoring that is loud, disruptive, or accompanied by gasping or breathing pauses may indicate obstructive sleep apnea — a condition where the airway closes fully during sleep and requires its own evaluation and treatment.
