What is sleep apnoea?

Sleep apnoea is a sleep-related breathing disorder in which airflow repeatedly reduces or stops during sleep. The most common form is obstructive sleep apnoea, where the upper airway narrows or collapses despite ongoing breathing effort.

In simple terms, the sleeper keeps trying to breathe, but the airway becomes too narrow for normal airflow. This can lead to snoring, oxygen desaturation, repeated brain arousals, and fragmented sleep.

A related test metric is the apnoea-hypopnoea index, or AHI, which estimates the number of breathing events per hour of sleep. A doctor uses AHI together with symptoms, oxygen levels, and clinical context rather than relying on one number alone.

If you are learning the basics first, Comooz explains sleep-disordered breathing concepts in its sleep education guides.

Why sleep apnoea matters in Singapore

Sleep apnoea matters because it affects health, safety, and daytime functioning. In Singapore, people often seek help because of loud snoring, unrefreshing sleep, poor concentration, or family members noticing breathing pauses.

Untreated sleep apnoea may be associated with hypertension, atrial fibrillation, and type 2 diabetes risk in some people. It may also worsen daytime sleepiness, which matters for commuters, shift workers, drivers, and people in safety-sensitive jobs.

Singapore patients also commonly ask whether snoring is “just snoring.” The practical answer is no if snoring comes with choking, witnessed pauses, morning headaches, or excessive daytime sleepiness. Those patterns justify medical review rather than guesswork.

In local practice, people also delay testing because they assume they must stay overnight in hospital, or that treatment automatically means surgery. In reality, many adults with suspected obstructive sleep apnoea can start with a home sleep test, and many are managed without surgery after doctor review.

Types of sleep apnoea: obstructive, central and mixed

Sleep apnoea is not one single condition. The three main categories are obstructive sleep apnoea, central sleep apnoea, and mixed sleep apnoea.

Obstructive sleep apnoea

Obstructive sleep apnoea (OSA) is the most common type. In OSA, the upper airway collapses or narrows during sleep while the body still makes breathing effort.

This form is often linked with snoring, obesity, nasal blockage, and airway anatomy. Many people who eventually use CPAP or APAP have obstructive sleep apnoea.

Central sleep apnoea

Central sleep apnoea happens when breathing effort temporarily decreases or stops because the brain’s respiratory control is unstable. The airway may be open, but the signal to breathe is reduced.

This type is less likely to present as classic loud snoring alone. It usually needs careful medical interpretation by a sleep physician.

Mixed sleep apnoea

Mixed sleep apnoea includes both obstructive and central features in the same patient or event pattern. Mixed patterns are one reason self-diagnosis is unreliable.

A proper sleep test and clinician review help determine which type is present and which treatment pathway is appropriate.

What causes sleep apnoea?

Sleep apnoea has several causes, depending on the type.

For obstructive sleep apnoea, the main issue is a physically narrow or unstable upper airway during sleep. Muscle tone falls as you sleep, and in some people the tongue, soft palate, or throat tissues narrow the airway enough to reduce airflow.

Common contributing factors include:

• weight gain or obesity
• a naturally narrow jaw or crowded airway
• large tonsils or soft tissue bulk
• nasal congestion or chronic rhinitis
• alcohol close to bedtime
• sedating medication in some cases
• sleeping flat on the back
• menopause and ageing-related airway changes

For central sleep apnoea, the issue is different. The airway may stay open, but breathing control becomes unstable because the brain’s drive to breathe fluctuates.

That is why treatment should follow proper diagnosis rather than assuming every snorer has the same condition.

Common symptoms and warning signs

The most common symptoms of sleep apnoea are loud habitual snoring, witnessed pauses in breathing, choking or gasping during sleep, and daytime sleepiness. Some people also notice poor memory, irritability, dry mouth, or morning headache.

Not every person with sleep apnoea feels sleepy. Some present mainly with poor sleep quality, reduced work performance, or a partner’s observation that breathing repeatedly stops.

Common warning signs include:

• loud snoring most nights
• witnessed apnoea or pauses in breathing
• waking with choking or gasping
• non-restorative sleep
• daytime sleepiness or unintended dozing
• morning headache
• poor focus or mood changes
• resistant hypertension

If symptoms are persistent, a doctor, ENT, or sleep specialist can advise whether testing is needed.

Who is at higher risk?

Sleep apnoea risk rises when airway anatomy, body habitus, and medical factors make breathing during sleep less stable. Obesity is a common risk factor, but it is not the only one.

People at higher risk often include those with:

• obesity or weight gain
• larger neck size
• loud chronic snoring
• family history of sleep apnoea
• nasal obstruction
• craniofacial or jaw anatomy that narrows the airway
• older age
• hypertension
• type 2 diabetes
• atrial fibrillation

Some slimmer patients also have obstructive sleep apnoea because anatomy matters. That is why risk screening should not be based on body size alone.

Men are often diagnosed more frequently, but women can also have sleep apnoea and may present differently, such as with fatigue, insomnia-like complaints, mood symptoms, or morning headaches rather than obvious witnessed apnoea.

How sleep apnoea affects the body

Sleep apnoea disrupts oxygen levels and repeatedly fragments sleep. Each event can trigger oxygen desaturation, stress responses, and brief arousals that prevent consolidated rest.

Over time, this pattern may affect cardiovascular, metabolic, and cognitive health. Sleep apnoea is associated with high blood pressure, poorer concentration, mood disturbance, and increased accident risk from fatigue.

The mechanism is straightforward: repeated upper airway obstruction causes interrupted airflow, unstable oxygenation, and recurrent sleep disruption. That is why even people who think they “sleep all night” may still wake unrefreshed.

Sleep apnoea complications if it is left untreated

Untreated sleep apnoea does not affect everyone in exactly the same way, but the possible consequences are important enough that persistent symptoms should not be ignored.

Possible complications may include:

• persistent daytime sleepiness
• reduced concentration and memory
• lower work productivity
• mood disturbance and irritability
• increased driving or workplace accident risk
• worsening blood pressure control
• cardiovascular strain
• poorer sleep quality for bed partners and family members

In Singapore, this often has a practical household effect too. Loud snoring in shared HDB flats or condominiums can disturb partners and family, and severe daytime fatigue can affect long commutes, shift work, and safety at work.

How sleep apnoea is diagnosed in Singapore

In Singapore, sleep apnoea diagnosis usually starts with a medical review and a sleep test. A doctor considers symptoms, examination findings, medications, medical history, and the right test format.

A home sleep test is a portable overnight study used outside a sleep lab. A Type 3 home sleep test is commonly used for suspected obstructive sleep apnoea, while Type 2 home testing can be arranged in selected cases with more channels and specialist setup.

A polysomnography study is a more comprehensive overnight sleep study, usually used when the case is more complex or when broader sleep evaluation is needed. A sleep specialist decides whether home testing or in-lab testing is more suitable.

Comooz supports home sleep test arrangements in Singapore, but diagnosis and treatment decisions should be made by a qualified clinician.

Who home sleep tests are for, and not for

A home sleep test is usually for adults with a straightforward suspicion of obstructive sleep apnoea. It is often chosen when the main questions are snoring, witnessed pauses, daytime sleepiness, and likely OSA.

A home sleep test is not a full replacement for every sleep study. If symptoms suggest central sleep apnoea, complex medical disease, unusual movements, narcolepsy, or another broader sleep disorder, a sleep physician may prefer polysomnography or a more supervised pathway.

Home sleep test vs polysomnography in Singapore

Many patients want to know which test is “better.” The more accurate answer is that the best test depends on the clinical question.

A Type 3 home sleep test is often a practical first step when suspected obstructive sleep apnoea is straightforward. It is more convenient, avoids a lab stay, and fits many adults with classic symptoms.

A Type 2 home sleep test gives more channels and may be arranged when more detail is needed at home.

Polysomnography is more comprehensive and is usually considered when:

• the diagnosis is unclear
• central sleep apnoea is a concern
• another sleep disorder may be present
• previous test results are borderline or inconsistent
• the patient has more complex medical issues

In practical terms, a straightforward snorer with witnessed pauses may start with home testing, while a more medically complex patient may be directed to a formal sleep lab pathway.

Sleep apnoea severity: what AHI numbers mean

AHI is the average number of apnoeas and hypopnoeas per hour of sleep. It is one of the main numbers used to describe sleep apnoea severity.

Standard AHI ranges

• 5 to 14.9: mild sleep apnoea
• 15 to 29.9: moderate sleep apnoea
• 30 or more: severe sleep apnoea

AHI is useful, but it is not the whole story. A doctor also reviews oxygen desaturation, event type, symptoms, sleep quality, and whether the test data are reliable enough to guide treatment.

What happens after a sleep apnoea test?

After the test, the next step is usually clinical interpretation rather than simply reading one number yourself.

A doctor or sleep specialist may review:

• AHI or related event index
• oxygen drops during the night
• whether the pattern looks obstructive, central, or mixed
• symptom severity
• whether the recording quality was adequate
• whether treatment or further testing is needed

For some patients, the result leads to conservative measures such as weight management, positional changes, or nasal treatment. For others, especially with moderate to severe obstructive sleep apnoea, CPAP may be discussed.

If the result does not fit the symptoms, further review or a different type of study may be advised.

Comparison table: snoring, home sleep testing, and CPAP options in Singapore

Patients usually want to compare both the condition and the next steps. The tables below summarise the differences in a format that is easier to act on.

Treatment options for sleep apnoea

Treatment depends on the type of sleep apnoea, AHI severity, symptoms, anatomy, and other health conditions. There is no single best treatment for everyone.

Options may include:

• weight management
• positional therapy
• reducing alcohol near bedtime
• nasal treatment if congestion is contributing
• oral appliances
• CPAP or APAP
• specialist ENT review
• selected surgical options

For obstructive sleep apnoea, CPAP is commonly recommended for moderate to severe disease. APAP is a form of positive airway pressure that auto-adjusts within a prescribed range and is commonly used in devices such as the ResMed AutoSet range.

Central or mixed sleep apnoea may need a different pathway and closer physician input.

Can sleep apnoea be cured?

Some people search for a cure, but the more medically accurate answer is that treatment depends on the cause and type.

In some patients, symptoms and severity may improve significantly with weight loss, positional therapy, treatment of nasal blockage, or other targeted interventions. In others, especially with ongoing anatomical airway collapse, long-term management such as CPAP may still be needed.

Because the condition varies so much, it is better to think in terms of assessment and treatment planning rather than assuming one permanent fix applies to everyone. A doctor or sleep specialist should advise what is realistic in your case.

How CPAP therapy works and who it may help

CPAP works by delivering pressurised air through a mask to keep the airway open during sleep. The pressure acts like a pneumatic splint that reduces upper airway collapse.

CPAP may help people with moderate to severe obstructive sleep apnoea and some people with symptomatic mild disease, depending on a doctor’s assessment. APAP devices such as the ResMed AirSense 10 AutoSet and ResMed AirSense 11 AutoSet adjust pressure automatically within settings prescribed during titration or clinical setup.

Comooz offers these machine bundles in Singapore:

CPAP, APAP, bilevel, EPAP, and titration

CPAP is often used as a general term, but the actual mode matters. APAP automatically adjusts pressure within a set range, while fixed-pressure CPAP delivers one prescribed pressure.

Titration is the process of determining effective pressure settings. For a smaller subset of patients who struggle with exhalation or need higher-pressure support, a physician may consider bilevel therapy, where expiratory pressure such as EPAP is managed differently on a platform like the ResMed AirCurve 10 VAuto.

Improving CPAP comfort and long-term adherence

CPAP comfort usually improves when pressure settings, humidification, and mask fit are matched to the patient. The goal is not just to own a machine, but to sleep well with it.

Mask choice matters

Mask comfort often determines whether a patient adapts successfully. The usual categories are nasal pillows, nasal masks, and full face masks.

• Nasal pillows suit people who want minimal facial contact.
• Nasal masks suit people who breathe well through the nose.
• Full face masks help when persistent mouth breathing or nasal blockage is present.

Humidification and pressure comfort

Built-in humidification can reduce dryness and improve tolerance. Both AirSense 10 and AirSense 11 bundles at Comooz include built-in humidification, which matters in real-world comfort more than many first-time users expect.

Pressure-related discomfort may improve with careful setup, follow-up, and, in some cases, pressure titration or bilevel review if exhalation difficulty is significant.

Singapore comfort tips: humidity, air-conditioning, and HDB living

Local conditions can affect comfort more than new users expect.

• In air-conditioned bedrooms, airflow can feel drier, so humidification settings may need adjustment.
• In Singapore’s humid climate, some users need tubing and humidity fine-tuning to reduce condensation or “rainout.”
• In shared bedrooms or HDB flats, quieter mask fit and lower leak rates can matter for partner comfort.
• If you travel between home, work stays, or overseas trips, portable packing and mask familiarity become part of adherence.

Small setup changes often make the difference between struggling with CPAP and using it consistently.

Trial and rental options

Some people with sleep apnoea want to test CPAP before buying. Comooz offers a structured 5-night CPAP trial, but it is not a free trial and requires a deposit, mask cost, and a SGD 98 return fee.

Comooz also offers monthly CPAP rental, with 3-month offset rules toward purchase. This can suit patients who want a practical transition period after diagnosis and initial setup.

How long does it take to get tested and start treatment?

Timing depends on the pathway chosen and whether the case is straightforward.

In a simple suspected OSA case, the flow is often:

• symptom review and suitability check
• home sleep test arrangement
• overnight recording
• clinician interpretation
• discussion of next steps such as CPAP, oral appliance, ENT review, or other measures

If a case is more complex, the timeline can be longer because in-lab polysomnography, specialist consultations, or further review may be needed.

For people who already have a diagnosis and are considering CPAP, machine selection, mask fitting, and adjustment usually matter just as much as speed.

When to see a doctor urgently

Urgent review is appropriate when symptoms suggest significant risk or a more complex problem. Severe daytime sleepiness, dangerous drowsy driving, marked choking episodes, or serious cardiopulmonary symptoms should not be left to online reading alone.

See a doctor promptly if you have:

• severe daytime sleepiness affecting driving or work safety
• witnessed repeated breathing pauses with distress
• chest pain, severe breathlessness, or concerning arrhythmia symptoms
• suspected central sleep apnoea or major medical complexity
• uncontrolled hypertension with strong sleep apnoea symptoms

An ENT or sleep physician may be involved depending on the pattern of symptoms and airway findings.

Frequently asked questions

What is the difference between snoring and sleep apnoea?

Snoring is a sound caused by vibration in the upper airway, while sleep apnoea involves repeated breathing interruptions or reductions during sleep. Some people who snore do not have sleep apnoea, but loud habitual snoring with choking, witnessed pauses, or daytime sleepiness should be assessed by a doctor or sleep specialist.

How is sleep apnoea tested in Singapore?

Assessment typically starts with a medical review of symptoms, risk factors, and sleep history. A doctor may recommend a home sleep test or an overnight polysomnography study, depending on the situation. The results help estimate breathing disturbances such as AHI, but diagnosis and treatment decisions should be made by a qualified clinician.

What AHI number counts as sleep apnoea?

AHI, or apnoea-hypopnoea index, measures the average number of breathing events per hour of sleep. In general, 5 to 14.9 is mild, 15 to 29.9 moderate, and 30 or more severe. A doctor interprets AHI together with symptoms, oxygen levels, medical history, and test quality before advising next steps.

Is sleep apnoea dangerous if left untreated?

It can be. Untreated sleep apnoea may be associated with daytime sleepiness, reduced concentration, poorer quality of life, and higher cardiovascular and metabolic risk in some people. It may also increase the risk of driving or workplace accidents. Anyone with suspected sleep apnoea should seek medical advice rather than self-diagnosing.

Is CPAP the only treatment for sleep apnoea?

No. Treatment depends on the type and severity of sleep apnoea, anatomy, symptoms, and other health conditions. Options may include weight management, positional therapy, oral appliances, nasal treatment, CPAP, and sometimes surgery. CPAP is commonly used for moderate to severe obstructive sleep apnoea, but a doctor should guide the choice.

Can I try CPAP before deciding whether to buy a machine?

Some providers in Singapore offer a structured CPAP trial, but it is usually not free. Comooz offers a 5-night CPAP trial with a deposit, mask fee, and a SGD 98 return fee. Suitability for a trial depends on prior assessment and should follow medical advice, especially if symptoms are severe or complex.

What causes sleep apnoea?

Obstructive sleep apnoea is usually caused by upper airway narrowing or collapse during sleep, often linked to weight gain, airway anatomy, nasal blockage, alcohol near bedtime, or sleeping position. Central sleep apnoea is different and relates to unstable breathing control. A sleep test helps clarify which pattern is present.

Can sleep apnoea go away on its own?

Sometimes severity can improve if a contributing factor changes, such as weight loss, reduced alcohol intake, improved nasal breathing, or positional changes. However, persistent symptoms or significant OSA should not be assumed to resolve without assessment. A doctor or sleep specialist should advise whether follow-up testing is needed.

How long does a sleep apnoea test take?

Most home sleep tests are done over one night. Polysomnography is also usually an overnight study, though scheduling, specialist review, and follow-up discussions can add time to the overall process.

What is the best sleeping position for sleep apnoea?

For some people with obstructive sleep apnoea, sleeping on the side may reduce airway collapse compared with sleeping flat on the back. But position is only one factor, and it is not enough for everyone. If symptoms are persistent, proper assessment is still important.

How much does CPAP cost in Singapore?

At Comooz, the ResMed AirSense 10 AutoSet Bundle is SGD 1,868 nett and the ResMed AirSense 11 AutoSet Bundle is SGD 2,068 nett. A structured 5-night CPAP trial is available, but it is paid and includes a deposit, mask cost, and a SGD 98 return fee.

Do I need to see an ENT or a sleep specialist for sleep apnoea?

That depends on the pattern of symptoms and likely cause. Some patients mainly need sleep testing and treatment planning, while others have prominent nasal blockage, tonsil issues, or airway anatomy concerns that justify ENT review. If symptoms are significant, start with a doctor or sleep specialist who can direct the right pathway.
