Why do I snore, and should I be worried?
Snoring is one of the most common complaints heard in ENT clinics, and one of the most frequently dismissed. Around 40% of adults snore regularly, making it one of the most common sleep-related complaints, and while it is often treated as little more than a nuisance, snoring can in some cases be a sign of a more significant underlying condition. Understanding why you snore, and when it warrants medical attention, is the first step towards addressing it. Snoring is common, but it is rarely random. In most cases, it reflects a specific, identifiable problem in how the airway behaves during sleep. Hillser Clinic's snoring and sleep wellness service covers assessment, diagnosis and treatment across the full spectrum of sleep-disordered breathing.
What actually causes snoring?
Snoring occurs when the flow of air through the mouth and nose is partially obstructed during sleep. As you relax into deeper sleep, the muscles of the throat, tongue and soft palate relax too. If the airway narrows sufficiently, the surrounding tissues begin to vibrate as air passes through, and it is that vibration which produces the characteristic sound of snoring.
Snoring is not caused by a single factor, but by a combination of anatomical and behavioural influences that reduce the airway during sleep. The degree of narrowing, and therefore the loudness and frequency of snoring, depends on a combination of anatomical and lifestyle factors. Some of the most common include:
Nasal obstruction: a deviated septum, enlarged turbinates, nasal polyps or chronic congestion can force you to breathe through your mouth, increasing the likelihood of throat vibration during sleep.
Soft palate anatomy: a long or floppy soft palate, enlarged tonsils or adenoids, or a small jaw can reduce the available airway space at the back of the throat.
Muscle tone: alcohol, sedatives and deep sleep stages all cause the throat muscles to relax more than usual, narrowing the airway further.
Body weight: excess weight, particularly around the neck, increases pressure on the airway and is one of the most modifiable risk factors for snoring.
Sleeping position: lying on your back allows the tongue and soft tissues to fall backwards, partially blocking the airway. Many snorers are significantly worse in this position.
Age: as we get older, the tissues of the throat naturally lose some of their tone, making snoring more common with age.
Taken together, these factors explain why snoring often develops gradually, and why it tends to worsen over time rather than appearing suddenly.
Is snoring always harmless?
Most snoring is not dangerous, but it is often dismissed too quickly. For many people, snoring is a straightforward mechanical issue: uncomfortable for those nearby, but not medically significant. However, snoring exists on a spectrum, and at the more serious end lies obstructive sleep apnoea (OSA), a condition in which the airway does not merely narrow but collapses repeatedly during sleep, causing the sleeper to stop breathing momentarily before rousing briefly to restore airflow.
OSA is more common than many people realise, and it is frequently underdiagnosed because the most dramatic symptoms (the pauses in breathing) occur when the patient is asleep and unaware. The consequences of untreated OSA extend well beyond disrupted sleep. It is associated with elevated blood pressure, increased cardiovascular risk, impaired glucose regulation, poor concentration, low mood and excessive daytime sleepiness. In drivers and those operating machinery, it carries real safety implications.
The transition from benign snoring to sleep apnoea is not always clear-cut, which is why any persistent or loud snoring deserves proper assessment rather than simple reassurance.
When should you see a doctor about snoring?
Persistent or loud snoring should not be ignored, particularly when it is accompanied by daytime symptoms or disrupted sleep. It is worth seeking a medical opinion about snoring if any of the following apply:
You have been told you stop breathing during sleep, or you wake yourself with a gasp or choking sensation.
You feel unrefreshed after a full night's sleep, or find yourself drowsy during the day without obvious explanation.
Your snoring is loud enough to disturb your partner or others in the household.
You wake frequently during the night, or notice your sleep is restless and broken.
You experience morning headaches, dry mouth on waking, or difficulty concentrating during the day.
Your snoring has worsened significantly, or you have recently gained weight.
These symptoms, taken together, may suggest that snoring is part of a broader sleep-disordered breathing picture. In many cases, problematic snoring is the first visible sign of obstructive sleep apnoea, a condition that often remains undiagnosed for years. A specialist assessment will determine whether further investigation, such as a home sleep study or drug-induced sleep endoscopy, is warranted.
What does assessment involve?
At Hillser Clinic, the assessment of snoring begins with a thorough consultation to understand your sleep patterns, symptoms and medical history. This is followed by a clinical examination that includes flexible nasendoscopy (FNE), a straightforward outpatient procedure in which a thin, flexible camera is used to examine the nasal passages and throat in detail.
Where sleep apnoea is suspected, a home sleep study may be recommended. This involves wearing a small, comfortable monitoring device overnight that records oxygen levels, breathing patterns and sleep stages. If the results suggest more complex obstruction, a drug-induced sleep endoscopy (DISE) may be arranged, a procedure in which mild sedation is used to reproduce the sleep state, allowing direct visualisation of precisely where the airway is collapsing.
This step-by-step diagnostic approach ensures that any treatment recommended is targeted to the actual cause of the problem, rather than generic.
What treatments are available?
Snoring is not a single condition but a symptom, and understanding its cause is the key to treating it effectively. Treatment depends on the underlying cause and severity, which is why assessment always precedes any recommendation.
For many patients, simple lifestyle adjustments produce meaningful improvement. These include weight loss, changes to sleeping position, reducing alcohol intake and addressing nasal congestion. Where structural anatomy is contributing, minimally invasive procedures such as coblation turbinate reduction or radio frequency treatment of the soft palate may be appropriate. In more complex cases, particularly where obstructive sleep apnoea has been confirmed, targeted surgical intervention or CPAP therapy may be considered.
The most important thing is not to dismiss persistent snoring as merely a social inconvenience. No two patients present identically, and the right approach is always specific to the individual. With the correct diagnosis in place, a clear and effective treatment pathway can almost always be established.
Frequently asked questions about snoring
Is snoring always a sign of sleep apnoea?
Not always. Most people who snore do not have obstructive sleep apnoea, though snoring is one of its most common early signs. The key distinction is whether the airway is narrowing during sleep, as in simple snoring, or collapsing repeatedly and causing breathing to pause, as occurs in OSA. A specialist assessment is the most reliable way to tell the difference.
What is the most common cause of snoring in adults?
The most common causes include nasal obstruction, soft palate anatomy and excess weight around the neck. In the majority of cases more than one factor is contributing, which is why a thorough clinical examination tends to be more informative than attempting to identify a single cause in isolation.
Can lifestyle changes stop snoring?
For some patients, yes. Weight loss, reducing alcohol intake, sleeping on your side and treating nasal congestion can all produce meaningful improvement. However, where structural factors such as a deviated septum, enlarged tonsils or poor soft palate tone are involved, lifestyle changes alone are unlikely to resolve the problem fully.
How do I know if my snoring is serious?
Snoring that is accompanied by witnessed pauses in breathing, excessive daytime sleepiness, morning headaches or consistently unrefreshing sleep warrants prompt assessment. These symptoms can indicate obstructive sleep apnoea, which carries real cardiovascular and metabolic risks when left untreated.
What happens at a snoring consultation at Hillser Clinic?
Assessment begins with a detailed consultation covering your sleep patterns, symptoms and medical history, followed by an ENT examination. A home sleep study or drug-induced sleep endoscopy may also be recommended, ensuring any treatment is precisely targeted to the cause.
Are there surgical options for snoring?
Yes, where anatomy is the primary contributor. Minimally invasive procedures including coblation turbinate reduction and radio frequency soft palate treatment can be performed as outpatient procedures. More targeted airway surgery is available for complex cases. We will recommend a surgical approach only where clinical findings clearly support it.
