What snoring is
During sleep, the muscles that hold the throat open relax. If the airway narrows, air passes faster and vibrates the soft palate, the uvula and the pharyngeal walls. That vibration is snoring.
A distinction is usually made between simple snoring — noisy but without impact on breathing — and snoring associated with obstructive apnea, where genuine breathing pauses occur. From the outside, the two can sound exactly the same. That is why habitual snoring deserves assessment.
When snoring is a warning sign
Isolated, occasional snoring without other symptoms is rarely concerning. The following signs, however, justify a sleep assessment:
- Someone has noticed you pause your breathing while asleep
- You wake with a choking, gasping or breathless sensation
- Sleepiness or fatigue during the day
- Very loud snoring, almost every night, or audible from another room
- High blood pressure, arrhythmias or diabetes
- Morning headaches or a very dry mouth on waking
Causes and risk factors
- Nasal obstruction: deviated septum, allergic rhinitis, polyps
- Enlarged tonsils and adenoids (especially in children)
- A long soft palate or bulky uvula
- Excess weight, with fat around the neck
- Alcohol or sedatives before bed, which relax the muscles further
- Sleeping on your back
- Smoking, which inflames and narrows the airways
- Age — muscle tone decreases over the years
How it is assessed
Assessment begins with a consultation including examination of the upper airway — nose, mouth and pharynx — to identify points of obstruction.
Whenever warning signs are present, we run a home sleep study. It is the test that distinguishes simple snoring from obstructive apnea, and that distinction completely changes treatment and prognosis.
Treatment options
Treating the nose
When there is nasal obstruction, resolving it is the first step and sometimes enough: treating rhinitis, correcting a deviated septum or removing polyps.
Positional therapy
If you snore mainly on your back, simple devices that keep you on your side can greatly reduce snoring.
Mandibular advancement device
A custom-made oral appliance that slightly advances the lower jaw, increasing pharyngeal space. Effective for snoring and mild to moderate apnea.
CPAP
If snoring is associated with sleep apnea, CPAP is the reference treatment: a small device that keeps the airway open overnight with gentle air pressure, eliminating both breathing pauses and snoring.
Habits
Losing weight, avoiding alcohol in the hours before bed, stopping smoking and keeping regular hours all have a direct, measurable effect on snoring.
Surgery
In selected cases, surgery of the palate, tonsils or nose may be indicated. The decision depends on the exact point of obstruction and on whether apnea is present.
When to seek help
Seek assessment if you snore almost every night, if snoring affects the rest of whoever sleeps next to you, or if you have any of the warning signs above. Treating snoring is often simple — but the first step is finding out whether it is only snoring.
Frequently asked questions
They can help when the cause is purely nasal and mild, but they do not treat the origin and have no effect on sleep apnea. If snoring is habitual, it is worth finding the cause rather than masking the symptom.
Yes, and habitual snoring in a child should never be considered normal. The most common cause is enlarged tonsils and adenoids, and the impact on growth, behaviour and school performance can be significant. It warrants assessment.
