Deformities of the nose or nasal septum, such as a deviated septum (a deformity of the wall that separates one nostril from the other) can also cause snoring and OSA. Sometimes, snoring only occurs during allergy season or with a cold or sinus infection. This creates an exaggerated vacuum in the throat that pulls together the floppy tissues of the throat. Obstructed nasal airways-A stuffy nose requires extra effort to pull air through it. The excessive length of the soft palate and/or uvula acts as a noisy flutter valve during relaxed breathing. Long soft palate and/or uvula-A long palate narrows the opening from the nose into the throat. Cysts or tumors are rare causes of airway narrowing. Those with very large tongues are especially susceptible to snoring and OSA. Overweight people may have excess soft tissue in the neck that can lead to airway narrowing. Alcohol or drugs that cause sleepiness may worsen muscle relaxation and obstruction.Įxcessive bulkiness of throat tissue-Children with large tonsils and adenoids often snore. Poor muscle tone in the tongue and throat-When muscles are too relaxed, the tongue falls backward into the airway, or the throat muscles draw in from the sides into the airway. What Other Factors Contribute to Snoring and Sleep Apnea? Obstruction in an adult may be due to a combination of factors in different areas, making it more challenging to identify and treat. In adults, the site of obstruction may not be as simple to identify.
In children, snoring may be a sign of problems with the tonsils and adenoids.
Apnea occurs when the obstruction of air flow is more severe, leading to reduced, compromised, or completely blocked air flow while trying to breathe. Snoring occurs when these structures strike each other and vibrate during breathing. This area is the collapsible part of the airway where the tongue and upper throat meet the soft palate and uvula. The noisy sounds of snoring occur when there is a partial obstruction to the flow of air through the passages at the back of the mouth and nose.
