Is Snoring Just a Habit? When Loud Snoring Could Be a Sign of Sleep Apnoea Wed , Oct 28

Occasional snoring is common, but loud, frequent snoring may sometimes indicate obstructive sleep apnoea (OSA), a condition in which breathing repeatedly becomes restricted or stops during sleep. If snoring occurs alongside gasping, witnessed breathing pauses or excessive daytime sleepiness, seek medical assessment to determine whether a sleep study is needed.

• Snoring happens when air causes relaxed tissues in the upper airway to vibrate during sleep.
• Loud snoring with pauses in breathing or gasping may indicate sleep apnoea.
• Morning headaches, dry mouth and daytime tiredness can also be warning signs.
• Untreated sleep apnoea is associated with high blood pressure, heart problems and an increased risk of fatigue-related accidents.
• A sleep study can help confirm the diagnosis and assess its severity.

Snoring occurs when airflow through the nose or throat becomes restricted during sleep. As the surrounding tissues relax and narrow the airway, they vibrate and produce the familiar snoring sound.

Common factors that can make snoring worse include:

• Sleeping on your back.
• Drinking alcohol close to bedtime.
• Nasal congestion.
• Excess body weight.
• Smoking or irritation of the upper airway.

Occasional snoring does not necessarily indicate a medical problem. However, persistent, loud snoring deserves attention when other symptoms are present.

Obstructive sleep apnoea occurs when the upper airway repeatedly narrows or closes during sleep, temporarily reducing or stopping airflow. These interruptions can disturb sleep and affect oxygen levels.

Look out for these symptoms:

• Loud, regular snoring.
• Pauses in breathing noticed by a partner or family member.
• Gasping, choking or snorting during sleep.
• Frequent waking during the night.
• Headaches or a dry mouth on waking.
• Excessive daytime sleepiness, poor concentration or irritability.

Snoring alone cannot confirm sleep apnoea. If you regularly snore and someone notices that your breathing stops during sleep, speak to a healthcare professional even if you do not feel particularly tired during the day.

Sleep apnoea can affect anyone, but certain factors increase the likelihood of developing it.

Common risk factors include:

• Being overweight or having obesity.
• A larger neck circumference.
• A family history of sleep apnoea.
• Persistent nasal blockage or certain airway and jaw features.
• Increasing age.
• Smoking and alcohol consumption.
• Hormonal changes, including menopause.

Having one or more risk factors does not mean you definitely have sleep apnoea. A clinical assessment is needed to determine whether testing is appropriate.

Repeated interruptions to breathing can prevent you from getting restorative sleep. Over time, untreated sleep apnoea is associated with several health concerns, including:

• High blood pressure.
• Heart and blood vessel conditions.
• Daytime fatigue and difficulty concentrating.
• Mood changes.
• A greater risk of accidents related to excessive sleepiness.

If you feel dangerously sleepy during the day, avoid driving or operating machinery until you have received appropriate medical advice.

Your doctor may ask about your snoring, sleep patterns, daytime symptoms and medical history. Information from a partner or family member who has observed your sleep can also be useful.

If sleep apnoea is suspected, a sleep study may be recommended. Depending on your circumstances, this may be performed at home or in a sleep clinic. The test records breathing-related information and helps determine whether sleep apnoea is present and how severe it is.

Treatment depends on the severity of the condition, its underlying causes and your individual needs.

Your doctor may recommend:

• Lifestyle changes: Weight management where appropriate, regular physical activity and reducing alcohol intake.
• Sleeping position changes: Side sleeping may help some people whose symptoms worsen when lying on their back.
• CPAP therapy: A machine delivers a steady flow of air through a mask to help keep the airway open during sleep.
• Oral appliances: Selected patients may benefit from a dentist-fitted device that helps maintain airway space.
• Other treatments: Specialist procedures or surgery may be considered in selected cases.

Lifestyle changes may reduce snoring, but they are not a substitute for prescribed sleep apnoea treatment.

If your snoring is occasional and not associated with warning signs, some changes may help:

• Try sleeping on your side.
• Avoid alcohol close to bedtime.
• Maintain a regular sleep schedule.
• Avoid smoking.
• Address persistent nasal congestion with appropriate medical advice.
• Maintain a healthy weight where possible.

If these measures do not help, or your snoring is loud and accompanied by breathing pauses or daytime sleepiness, arrange a medical assessment.

Snoring may seem harmless, but frequent loud snoring accompanied by gasping, breathing pauses or daytime sleepiness can be a sign of sleep apnoea.

If you or someone close to you notices these symptoms, consult a healthcare professional. Early assessment can help identify the problem and guide appropriate treatment for better sleep and long-term health.
