Loud Snoring? When Should You Worry About Sleep Apnoea?

Does your partner complain about your loud snoring? Have they noticed that you sometimes stop breathing briefly during sleep? Or do you wake up feeling tired despite what seemed like a full night's sleep? These symptoms deserve attention, particularly when they occur together.

Sleep apnoea is a condition in which breathing repeatedly stops and starts during sleep. The most common form, obstructive sleep apnoea, occurs when the upper airway becomes narrowed or blocked during sleep. Snoring alone does not establish a diagnosis, but a combination of symptoms may warrant assessment.

Five warning signs of sleep apnoea

1. Loud and frequent snoring

Many people snore without having sleep apnoea. However, frequent loud snoring, particularly when interrupted by pauses in breathing, can be a reason to seek assessment.

2. Pauses in breathing during sleep

A partner may notice that your breathing appears to stop briefly and then resume, sometimes followed by a snort, gasp or sudden change in breathing pattern. People may not remember these episodes the next morning, so observations from a family member can be useful.

3. Gasping or choking at night

Some people make choking, snorting or gasping sounds while sleeping. Repeated episodes, especially alongside loud snoring or observed breathing pauses, warrant medical assessment.

4. Daytime sleepiness and poor concentration

Sleep apnoea can fragment sleep and contribute to tiredness, reduced alertness, difficulty concentrating, irritability or waking unrefreshed. These symptoms can also result from insufficient sleep, medication effects and other medical or sleep conditions.

5. Morning headaches

Some people with sleep apnoea report headaches on waking, but morning headaches have many possible causes. If they occur alongside loud snoring, witnessed breathing pauses or excessive daytime sleepiness, discuss the combination with a clinician.

Why does obstructive sleep apnoea happen?

During sleep, muscles supporting the upper airway relax. In some people the airway narrows or temporarily collapses, interrupting airflow. Factors associated with increased likelihood include excess body weight, certain upper-airway characteristics, increasing age and family history. Sleep apnoea can also occur in people who are not overweight.

Can sleep apnoea affect brain health?

Repeated sleep disruption can contribute to daytime sleepiness, impaired concentration and difficulties with memory or decision-making. Untreated sleep apnoea is associated with cardiovascular conditions including high blood pressure and stroke, although not everyone with sleep apnoea will develop these complications.

Sleepiness and driving safety

Excessive daytime sleepiness can impair attention and reaction time. If you feel dangerously sleepy or struggle to stay awake, do not drive. Arrange alternative transport and seek medical assessment.

How is sleep apnoea diagnosed?

A clinician may ask about snoring, witnessed breathing pauses, daytime sleepiness, sleep habits, medical conditions and medicines. Symptoms alone cannot reliably confirm the diagnosis.

What is a sleep study?

A sleep study measures aspects of breathing and other body functions during sleep, which may include airflow, breathing effort, oxygen levels and heart rate. Some people can use a suitable portable device at home; others may need an overnight study in a sleep centre. The appropriate test depends on clinical circumstances.

What treatments are available?

Treatment depends on diagnosis, severity, symptoms and individual circumstances. Depending on the person, lifestyle measures may include weight management when appropriate, regular physical activity, avoiding alcohol close to bedtime, stopping smoking and considering side-sleeping if symptoms worsen on the back. These measures do not replace prescribed treatment when it is needed.

CPAP therapy

Continuous positive airway pressure (CPAP) uses a mask and machine to deliver pressurised air that helps keep the upper airway open during sleep. It is an established treatment option for obstructive sleep apnoea. A clinician can discuss suitability and help address comfort or use problems.

Oral appliances and other treatments

Some patients may benefit from a custom-fitted oral appliance. Selected patients may be considered for other treatments, including surgery, depending on anatomy, clinical findings and response to other approaches. No single treatment is best for everyone.

When should you seek medical advice?

Arrange assessment if you or your partner notice repeated pauses in breathing, gasping or choking at night, frequent loud snoring with other symptoms, persistent daytime sleepiness or regularly waking unrefreshed. If daytime sleepiness makes driving unsafe, do not drive until you have received appropriate advice and can remain alert safely.

Frequently asked questions

Does everyone who snores have sleep apnoea?

No. Snoring is common and does not automatically indicate sleep apnoea. Repeated breathing pauses, gasping during sleep and daytime sleepiness make assessment particularly important.

Can sleep apnoea cause morning headaches?

Morning headaches can occur in people with sleep apnoea, but they have many possible causes. Persistent headaches alongside snoring and daytime sleepiness deserve assessment.

Is a sleep study always required?

Not everyone who snores needs a sleep study. When sleep apnoea is suspected, a clinician can decide whether testing is appropriate and which type of study is suitable.

Can sleep apnoea occur in people who are not overweight?

Yes. Excess weight is one risk factor, but it is not necessary for someone to develop obstructive sleep apnoea.

Can sleep apnoea affect concentration and memory?

Sleep apnoea can disrupt sleep and contribute to problems with concentration, memory and decision-making. These symptoms can also occur with other conditions.

The key takeaway

Loud snoring does not always mean sleep apnoea. However, snoring combined with breathing pauses, gasping or excessive daytime sleepiness should not be ignored. A clinical assessment and, when indicated, a sleep study can help establish the diagnosis and guide treatment.
