Sleep Apnoea: Why an ENT Specialist in Singapore Matters for Your Work Performance and Heart Health

You can spend eight hours in bed and still wake up tired. You snore, you feel foggy by mid-afternoon, and you put it down to stress or a busy schedule. For many adults in Singapore, the underlying cause may be sleep apnoea, a breathing disorder that develops unnoticed during sleep.

It is more common than most people realise. The Singapore Health Study found that around 30.5% of adults here have moderate to severe obstructive sleep apnoea (OSA), and up to 91% of them have never been diagnosed. Left untreated, it can quietly affect work performance and raise the risk of heart disease. For individuals experiencing symptoms such as persistent snoring, daytime fatigue, or disrupted sleep, an assessment by an ENT specialist in Singapore is often recommended to clarify the diagnosis and discuss appropriate management options.

What Is Sleep Apnoea, and Why Is It a “Silent” Disorder?

Obstructive sleep apnoea happens when the soft tissues of the upper airway relax and collapse during sleep. This blocks airflow for several seconds at a time, sometimes dozens or hundreds of times a night.

Each pause lowers the oxygen in your blood and prompts your brain to rouse you briefly so breathing can restart. You rarely remember these moments, which is part of why the condition is so easy to miss.

It is often called “silent” because the effects build while you sleep, when you are least aware of them. A bed partner usually notices the snoring and gasping before the person affected suspects anything is wrong.

Common Signs and Symptoms

• Loud, persistent snoring
• Pauses in breathing, gasping, or choking during sleep, often noticed by a partner
• Waking unrefreshed despite a full night in bed
• Excessive daytime sleepiness or fatigue
• Morning headaches and a dry throat
• Poor concentration, memory lapses, or low mood

How Sleep Apnoea Affects Work Performance

Broken sleep robs the brain of the deep rest it needs. The result is daytime sleepiness, slower thinking, and weaker focus, and these show up directly at work.

Researchers describe two costs: absenteeism, meaning missed days, and presenteeism, meaning being at your desk but underperforming. A meta-analysis found that people with OSA are nearly twice as likely to be involved in work-related accidents.

For drivers, machine operators, and anyone making high-stakes decisions, that risk matters. The encouraging point is that treatment can help. Many patients report fewer sick days once their sleep apnoea is properly managed.

The Link Between Sleep Apnoea and Heart Health

Every time breathing stops, oxygen levels fall, and the body releases stress hormones. This repeatedly raises blood pressure and strains the heart, night after night, over the years.

Over time, untreated OSA is associated with:

• High blood pressure (hypertension)
• Heart attack and coronary artery disease
• Stroke
• Irregular heart rhythms, such as atrial fibrillation
• Type 2 diabetes

These are not rare footnotes. They are why doctors treat sleep apnoea as a cardiovascular concern, not simply a sleeping nuisance.

Can an ENT Specialist Help with Sleep Apnoea?

Yes. An ENT specialist, also called an ear, nose, and throat specialist, is often well placed to assess and treat sleep apnoea, because the obstruction usually sits in the upper airway, which is the ENT specialist’s main area of focus.

A blocked nose plays a larger role than many expect. A deviated septum, enlarged turbinates, nasal polyps, or chronic rhinitis can all worsen snoring and OSA, and can make therapies like CPAP harder to tolerate. This is where an ENT specialist with a focus on the nose and sinuses can play a useful role. 

How Sleep Apnoea Is Diagnosed

Diagnosis usually pairs an ENT evaluation with a sleep study. The specialist examines your nose, throat, and airway, often using a thin nasal endoscope. A sleep study, done overnight in a lab or with a home testing kit, then measures how many times your breathing pauses each hour. This score is called the apnoea-hypopnoea index (AHI), and it grades how mild or severe the condition is.

Common treatment options at a glance

“Many patients come in thinking snoring is purely a social problem. In reality, it can be a sign that the airway is collapsing during sleep. Addressing the nose and the rest of the upper airway can be a useful part of the overall treatment plan and may support how well other treatments work.”

— Dr Gan Eng Cern, ENT Specialist, Singapore

It is worth knowing that CPAP works well for many people, but is not always easy to keep up with. In one local study of patients diagnosed with OSA, only about 13.8% were using CPAP regularly a year later, partly because many did not start it or moved to other treatments. That is why a treatment plan tailored to each patient, rather than a one-size-fits-all device, matters so much.

How Much Does It Cost to See an ENT Specialist in Singapore?

Fees vary with the specialist’s experience and the complexity of your visit. At Dr Gan’s clinic, consultation fees start from SGD 196.20 (including GST) for a visit of up to 30 minutes. A sleep study and any procedures are charged separately, based on what your assessment shows.

Financial considerations are also important when planning ENT treatment. Many ENT procedures are Medisave-claimable, and coverage may be available through major health insurance providers. Patients are encouraged to review their benefits and confirm eligibility with their insurer before proceeding with treatment.

How to Choose an ENT Specialist in Singapore

The right choice depends on your condition, so a useful question is who is well suited to your particular needs.

When choosing an ear, nose, and throat specialist in Singapore, it helps to look for:

• Full accreditation and registration as an ENT specialist
• Subspecialty experience that matches your problem; for snoring and OSA, a focus on the nose and airway is useful
• Clear communication and a treatment plan you understand

Dr Gan Eng Cern is a fellowship-trained ENT specialist with a subspecialty interest in nose and sinus conditions, practising at Mount Elizabeth Novena Hospital. His clinical experience includes the evaluation and management of sleep apnoea, snoring, and other disorders affecting the ear, nose, and throat.

The Takeaway

Sleep apnoea rarely announces itself. It hides behind snoring, tiredness, and the feeling that you are simply busy, while quietly taxing your focus and your heart.

If you wake unrefreshed most mornings, the question worth asking is a simple one: is this just a hectic season of life, or is your body signalling something more? An assessment by an ENT specialist in Singapore can help identify the underlying cause and guide an appropriate management plan.
