What is snoring? Snoring is the sound produced when relaxed tissues in the upper airway vibrate as air passes during sleep. Occasional snoring can happen with a cold, allergy, tiredness or sleeping on the back. Regular loud snoring deserves attention because it may disturb sleep and can be a sign of obstructive sleep apnea.
Common causes Snoring may be related to nasal congestion, allergy, a deviated septum, enlarged turbinates, large tonsils or adenoids, excess soft tissue around the throat, alcohol, sedating medicines, smoking or sleep position. In adults, obstruction may occur at more than one level of the airway.
When is snoring a medical concern? Warning signs include witnessed pauses in breathing, gasping or choking, restless sleep, morning headaches, daytime sleepiness, poor concentration and high blood pressure. In children, regular snoring may be associated with mouth breathing, behavioural problems, bedwetting, poor school performance or growth concerns.
Assessment An ENT examination can assess the nose, mouth, throat, palate and neck. Flexible endoscopy may be used to identify obstruction. A sleep study may be required when sleep apnea is suspected. Recording the snoring or asking a bed partner about breathing pauses can help the clinical history, but it does not replace testing.
Treatment Treatment should target the cause. Measures may include weight management when relevant, reducing alcohol near bedtime, stopping smoking, treating allergy or nasal inflammation, changing sleep position, using a custom oral appliance or treating confirmed sleep apnea with CPAP. Surgery may be considered for selected structural problems, but no single operation is appropriate for every patient.
Anti-snoring products Over-the-counter products may reduce symptoms for some people, but they should not delay evaluation when warning signs of sleep apnea are present. Mouth devices should be properly assessed and fitted because an unsuitable device may cause jaw or dental problems.
When should you see a doctor? Seek assessment for loud habitual snoring, breathing pauses, choking, significant daytime tiredness or snoring in a child on most nights.

Frequently Asked Questions
Is snoring always dangerous?
No. Occasional snoring may be harmless, but regular loud snoring with other symptoms requires assessment.
Can nasal blockage cause snoring?
Yes. Allergy, septal deviation and other nasal problems may contribute.
Does sleeping on the side help?
It can reduce position-related snoring in some people, but it does not treat every cause.
Should a child who snores be checked?
Regular snoring in children should be discussed with a clinician, especially with breathing pauses or behavioural changes.
Can surgery stop all snoring?
No treatment guarantees complete resolution. Surgery is chosen according to the site and cause of obstruction.
