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. It is estimated that around 40 per cent of adults snore regularly, 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.
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.
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.
Is snoring always harmless?
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?
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. 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?
Treatment depends entirely on the underlying cause and severity. For many patients, simple measures — weight loss, sleeping position adjustment, reducing alcohol intake, and addressing nasal congestion — produce meaningful improvement. Where anatomy is contributing significantly, surgical options ranging from minimally invasive nasal procedures (including coblation and radio frequency) to more targeted airway surgery may be appropriate.
The most important thing is not to dismiss persistent snoring as merely a social inconvenience. With the right assessment, the cause can almost always be identified and a tailored treatment plan put in place.
