Sleep Apnea Treatment in Singapore
Sleep apnea is a condition in which breathing repeatedly becomes reduced or stops during sleep, disrupting rest and affecting overall health. If you are looking for sleep apnea treatment in Singapore, Dr Leslie Koh is a sleep apnea doctor who provides ENT assessment for obstructive sleep apnea (OSA), including airway evaluation, guidance on sleep apnea testing, and personalised treatment options such as non-surgical therapy and selected surgical management.
Dr Leslie Koh provides ENT assessment for obstructive sleep apnea (OSA), including evaluation of the upper airway, guidance on sleep apnea diagnosis, and discussion of suitable treatment options. Depending on the individual case, treatment may include non-surgical management such as CPAP, oral appliance therapy, and lifestyle measures, or selected surgical treatment where structural narrowing of the airway is involved.
How Common is Sleep Apnea in Singapore?
Sleep apnea is increasingly recognised as a common health condition in Singapore, particularly among adults. Findings from healthcare institution–based studies indicate that obstructive sleep apnea (OSA) is relatively common in Singapore, with an estimated 30.5% of the population affected by moderate to severe OSA.
Despite its prevalence, many individuals remain undiagnosed, as symptoms such as snoring, unrefreshing sleep, or daytime tiredness are often overlooked or attributed to lifestyle factors. Variations in prevalence estimates are influenced by age, body weight, and the diagnostic thresholds used in different studies. These findings highlight that sleep apnea is not uncommon locally and warrants clinical attention when symptoms persist.
What Is Sleep Apnea?
Sleep apnea is a sleep-related breathing disorder where breathing repeatedly stops and starts during sleep. These interruptions can occur due to reduced or blocked airflow. Some may be caused by breathing effort that temporarily decreases. Each episode possibly leads to brief awakenings from sleep, often without the person being aware of them.
Over time, repeated disruptions may affect sleep quality and oxygen levels during the night. Common features include loud snoring, pauses in breathing observed by others, and non-restorative sleep. A structured medical evaluation is required to determine whether symptoms are due to sleep apnea or another sleep or airway-related condition, and to guide appropriate management based on individual findings.
What Are the Types of Sleep Apnea?
Obstructive Sleep Apnea (OSA)
In OSA, the airway becomes blocked during sleep, preventing airflow to the lungs. This is the most common form of sleep apnea. The severity of OSA is measured using the Apnea-Hypopnea Index (AHI), which tracks the frequency of breathing interruptions per hour of sleep.
Central Sleep Apnea (CSA)
CSA occurs when the brain does not send proper signals to the breathing muscles, resulting in pauses in breathing even when the airway remains open.
Mixed (or Complex) Sleep Apnea
Mixed sleep apnea is a combination of OSA and CSA, where both airway obstruction and signalling issues are involved.
What Are the Symptoms of Sleep Apnea?
Symptoms of sleep apnea often occur both during sleep and throughout the day due to poor sleep quality. While there is a significant overlap in symptoms between obstructive sleep apnea (OSA) and central sleep apnea (CSA), some key differences exist.
Common Symptoms
Difficulty concentrating
Reduced oxygen levels and poor sleep quality can make it challenging to focus on daily tasks or recall information.
Daytime sleepiness (hypersomnia)
People may feel exhausted during the day, sometimes dozing off unintentionally at work, while reading, or even driving.
Morning headaches
Waking up with headaches may result from low oxygen and disturbed sleep during the night.
Insomnia
Some individuals struggle to stay asleep due to repeated breathing disruptions, leading to restless nights.
Irritability and mood swings
Poor sleep may affect emotional regulation, contributing to irritability, low mood, or heightened stress.
Symptoms More Specific to Obstructive Sleep Apnea (OSA)
Loud, frequent snoring
A common feature, often noticed more by a bed partner than the person themselves.
Witnessed breathing pauses
Breathing may stop during sleep, followed by a sudden snort, choke, or gasp as normal breathing resumes.
Night sweats
Some individuals experience increased perspiration during sleep as the body struggles with disrupted breathing.
Frequent night urination
Waking up multiple times to urinate is a recognised feature associated with OSA.
Symptoms More Specific to Central Sleep Apnea (CSA)
Abrupt awakenings with shortness of breath
Breathing interruptions may cause sudden awakenings accompanied by a feeling of breathlessness.
Nocturnal chest pain
Some people may notice discomfort or pressure in the chest during the night.
Cheyne–Stokes breathing
This is a distinct pattern of irregular breathing marked by cycles of shallow breaths, deep breaths, and pauses.
Note: Not everyone with sleep apnea snores. If symptoms persist, consider medical evaluation.
What Causes Sleep Apnea and Who is at Risk?
Sleep apnea does not have a single cause. Instead, several factors may increase the likelihood of developing the condition. These vary from person to person and do not always lead to sleep apnea, but they may play a role in increasing the risk.
Excess Weight and Fat Deposition Around the Airway
Obesity is a major risk and may increase soft tissue around the neck and throat. This can narrow the upper airway and make it more prone to collapse during sleep, especially when the throat muscles naturally relax at night. In some patients, even a modest increase in tissue around the airway can increase airflow resistance and worsen snoring or OSA symptoms.
Age-Related Reduction in Muscle Tone
As people age, the muscles that help maintain airway patency during sleep may become less effective. This loss of tone can make the airway more collapsible, especially when other contributing factors such as weight gain, structural crowding, or nasal blockage are also present.
Family history
Having close relatives with sleep apnoea may increase the likelihood of developing the condition, suggesting a genetic component.
Lifestyle: smoking, alcohol, or sedative use:
These may relax the muscles of the airway or irritate the respiratory passages, which can contribute to breathing disruptions during sleep.
Narrow airway structure
Some people naturally have a smaller airway or larger tonsils and adenoids, which may make airflow more difficult.
Sleeping position
Lying on the back may encourage the tongue and soft tissues to fall backwards, potentially obstructing the airway.
How is Sleep Apnea Diagnosed in Singapore
Sleep apnea diagnosis usually begins with a structured consultation. The aim is not just to confirm whether OSA may be present, but also to understand the pattern of symptoms, identify contributing risk factors, and assess whether anatomical narrowing may be involved.
Medical History and Symptom Review
The diagnostic process often starts with a review of:
- Snoring pattern and severity
- Witnessed breathing pauses
- Choking or gasping episodes
- Daytime fatigue or sleepiness
- Morning headaches
- Sleep habits and sleep quality
- Relevant medical history and risk factors
This helps determine how likely sleep apnea may be and whether further testing is needed.
What Complications Can Sleep Apnea Cause?
Sleep apnea may be linked with several health conditions. These associations have been observed in clinical studies, though the extent of risk can vary from person to person.
High blood pressure (hypertension)
Repeated drops in oxygen during sleep may contribute to elevated blood pressure levels.
Heart disease
Sleep apnoea is associated with an increased strain on the heart, which may affect heart rhythm and circulation.
Stroke
Breathing interruptions and reduced oxygen may be related to a higher risk of stroke in some individuals.
Type 2 diabetes
Research has found connections between disrupted sleep and changes in glucose metabolism.
Weight gain
Poor sleep can affect hormone balance and appetite regulation, which may contribute to weight changes.
Sexual dysfunction
Studies have reported links between sleep apnoea and erectile dysfunction.
What Non-Surgical Treatments Are Available for Obstructive Sleep Apnea (OSA)?
Non-surgical approaches are often considered first when managing sleep apnea. These methods focus on keeping the airway open and improving breathing during sleep.
CPAP (Continuous Positive Airway Pressure)
A device that delivers a steady flow of air through a mask to prevent airway collapse.
BiPAP (Bilevel Positive Airway Pressure)
Provides two pressure settings — higher when inhaling and lower when exhaling — which may be more comfortable for some individuals.
Adaptive Servo-Ventilation (ASV)
A type of device that adjusts airflow automatically during sleep, sometimes used in central or complex sleep apnea.
Oral appliances (mandibular advancement devices)
Custom-made devices worn in the mouth to help move the lower jaw forward, allowing better airflow.
Positional therapy
Encourages sleeping in positions that reduce airway obstruction, often avoiding sleeping on the back.
These options form part of the commonly used OSA treatment in Singapore and may be tailored depending on the severity and type of sleep apnea.
What Surgical Treatments Are Available for Sleep Apnea?
When non-surgical methods are not effective, surgery may be considered. Surgical procedures aim to remove or reduce tissue that blocks the airway or to alter airway structure.
Upper airway surgery (tonsillectomy and adenoidectomy)
Removal of enlarged tonsils or adenoids that may obstruct breathing.
Uvulopalatopharyngoplasty (UPPP/UP3)
A procedure that reshapes the soft palate and surrounding tissue to widen the airway.
Inferior turbinate reduction
Reduces the size of the turbinates in the nose to improve airflow.
Septoplasty
Corrects a deviated nasal septum that may contribute to airway blockage.
Tongue base reduction
Removes or reduces tissue at the base of the tongue to prevent it from blocking the airway during sleep.
Soft palate stiffening
Reinforces the palate to lessen collapse and vibration during breathing.
These procedures are part of the range of treatment options for obstructive sleep apnea. In some instances, a sleep apnea surgeon may recommend surgery if other methods are not sufficient. Each approach is considered on an individual basis as part of broader sleep apnea treatment in Singapore.
When to See a Sleep Apnea Doctor in Singapore
You should consider seeing a sleep apnea doctor in Singapore if:
- You snore loudly and regularly
- Someone has noticed pauses in your breathing during sleep
- You wake feeling tired even after a full night’s rest
- You have morning headaches or dry mouth
- You feel sleepy in the day or struggle with concentration
- You suspect nasal blockage or airway narrowing may be affecting sleep
- Snoring or poor sleep is affecting your partner or daily functioning
An ENT assessment may be particularly useful where upper airway structure, nasal blockage, throat anatomy, or snoring are part of the picture.
FAQs about Sleep Apnea in Singapore
What is the difference between snoring and sleep apnea?
Snoring occurs when tissues in the throat vibrate due to partially blocked airflow. Sleep apnea, on the other hand, involves repeated pauses in breathing that can lower oxygen levels and disturb sleep. Learn more about ENT snoring.
When should I see a doctor for sleep apnea?
If you or someone close to you notices loud snoring, pauses in breathing during sleep, or excessive daytime tiredness, it may be time to seek a medical assessment. Persistent morning headaches, mood changes, or difficulty concentrating are also signs that should not be ignored.
Can sleep apnea go away on its own?
In some mild cases, weight reduction or lifestyle adjustments may lessen symptoms, but sleep apnea does not usually resolve without medical attention. A formal diagnosis is often needed to understand the severity and guide treatment.
Is sleep apnea common in children?
Yes. Enlarged tonsils or adenoids are common causes in children and can lead to restless sleep, loud snoring, or mouth breathing. A pediatric ENT specialist can assess whether treatment is required.
Does nasal allergy affect sleep apnea?
Blocked nasal passages due to allergies may make breathing harder at night and worsen existing sleep apnea. Managing allergies, such as a sensitive nose allergy, may help improve airflow during sleep.
Can lifestyle changes help with sleep apnea?
Yes. Avoiding alcohol and sedatives before bedtime, maintaining a healthy weight, and changing sleeping position may reduce symptoms. While these changes can be helpful, they are usually part of a broader management plan.
How is sleep apnea diagnosed?
Doctors use clinical evaluation and sleep studies to confirm the condition. This may include an overnight polysomnography in a sleep lab or a home sleep test to measure breathing and oxygen levels.
What happens if sleep apnea is untreated?
Untreated sleep apnea may be linked with long-term health issues such as high blood pressure, heart disease, diabetes, and an increased risk of stroke. Early diagnosis and management can help reduce these risks.
