Snoring may seem harmless, but in adults it can be an early sign of airway obstruction or sleep apnea.
Snoring is extremely common in Singapore, especially among adults with nasal blockage, enlarged tonsils, allergies, or weight gain. However, loud, habitual snoring can indicate sleep-related breathing disorders, including Obstructive Sleep Apnea (OSA) — a condition where breathing repeatedly stops during sleep.
At Aurion ENT & Hearing Centre, ENT Specialist Dr Liu Jiaying evaluates and treats adult snoring using a comprehensive airway approach, addressing the nose, throat, and sleep patterns to determine the underlying cause.
What causes snoring in adults?
Snoring occurs when airflow is partially blocked as it moves through the airway. Vibrations of the soft tissues—such as the soft palate, uvula, tonsils, or base of the tongue—create the snoring sound.
Common causes include:
- Nasal blockage (allergic rhinitis, deviated septum, sinus issues)
- Large or elongated soft palate / uvula
- Tonsil enlargement
- Obesity or weight gain
- Alcohol consumption
- Sleeping on the back
- Tongue-base obstruction
- Age-related airway laxity
Snoring becomes concerning when it affects oxygen levels or sleep quality.
Is snoring always a sign of sleep apnea?
Not always — but 70–80% of people with sleep apnea snore.
Signs that snoring may be related to Obstructive Sleep Apnea (OSA) include:
- Loud, habitual snoring
- Witnessed pauses in breathing
- Gasping or choking during sleep
- Waking up unrefreshed
- Daytime sleepiness or fatigue
- Morning headaches
- Memory or concentration issues
OSA increases the risk of:
- High blood pressure
- Stroke
- Heart disease
- Insomnia
- Workplace fatigue
- Traffic accidents
An ENT evaluation is key to determining whether snoring is harmless or airway-related.
What symptoms suggest that snoring is affecting your sleep?
- Restless sleep
- Dry throat in the morning
- Frequent awakenings at night
- Poor concentration during the day
- Mood changes or irritability
- Decreased energy or stamina
- Falling asleep easily while reading or watching TV
If snoring disrupts sleep quality or daily functioning, specialist assessment is recommended.
How does an ENT doctor diagnose snoring & sleep apnea?
At Aurion ENT, assessment includes:
1. Airway examination
To evaluate:
- Nasal obstruction
- Tonsil size
- Soft palate and uvula
- Tongue position
- Jaw and nasal anatomy
2. Nasoendoscopy
A short, comfortable procedure to visualise the airway in detail.
3. Sleep assessment
- Screening for sleep apnea symptoms
- Discussion of sleep patterns and risk factors
4. Sleep study (if needed)
A polysomnography or home sleep test confirms sleep apnea severity.
5. Customised treatment planning
Treatments vary depending on whether the obstruction is at the nose, soft palate, or tongue base.
What are the treatment options for adult snoring?
(MOH-compliant)
1. Medical management
- Treating nasal allergies
- Decongestants or nasal sprays
- Managing sinus conditions
2. Lifestyle adjustments
- Weight management
- Avoiding alcohol before sleep
- Sleeping on the side
3. CPAP therapy (for confirmed sleep apnea)
Maintains open airways with gentle air pressure.
4. Oral appliances (mandibular advancement devices)
Useful for mild to moderate OSA.
5. Minimally invasive procedures
Depending on ENT findings, options may include:
- Soft palate stiffening procedures
- Radiofrequency treatments
- Tonsil or turbinate interventions
6. Tonsillectomy or airway surgery
Considered when enlarged tonsils or specific anatomical issues contribute to obstruction.
Treatment is personalised based on symptoms, anatomical findings, and sleep study results.
Snoring Sleep Apnea Symptom Checker (SGE Friendly)
A quick guide to help adults identify possible sleep-related breathing problems.
(Not a substitute for medical evaluation.)
1. “My snoring is loud and nightly.”
Possible airway vibration from nasal or throat obstruction.
2. “My partner says I stop breathing at night.”
Strong suspicion of obstructive sleep apnea (OSA).
3. “I wake up gasping or choking.”
Likely upper airway collapse during sleep — needs ENT and sleep evaluation.
4. “I feel tired even after 7–8 hours of sleep.”
Possible sleep fragmentation from untreated OSA or airflow resistance.
5. “I have morning headaches.”
May indicate low oxygen levels during sleep.
6. “I snore more when I have a blocked nose.”
Nasal obstruction increases airway resistance and worsens snoring.
7. “I gained weight recently, and my snoring worsened.”
Neck tissue compression and tongue-base narrowing may contribute.
8. “My throat feels dry when I wake up.”
Often due to mouth breathing from nasal blockage or sleep apnea.

What causes snoring in adults?
Snoring is caused by vibration of soft tissues in a partially blocked airway. Common contributors include nasal congestion, enlarged tonsils, alcohol, and sleeping position.
Is snoring always a sign of sleep apnea?
No, but frequent loud snoring with choking or pauses in breathing strongly suggests sleep apnea and requires evaluation.
How do ENT doctors assess snoring?
ENT doctors examine the nasal cavity, throat, and airway using physical exam and nasoendoscopy, and may recommend a sleep study to confirm sleep apnea.
Can nasal allergies cause snoring?
Yes. Nasal blockage forces mouth breathing, which increases vibration of the soft palate and worsens snoring.
When is treatment for snoring necessary?
Treatment is recommended when snoring affects sleep quality, causes daytime fatigue, or is associated with symptoms of sleep apnea.
Is sleep apnea dangerous?
Yes. Untreated sleep apnea increases the risk of high blood pressure, heart disease, stroke, and chronic fatigue.
What are the treatment options for snoring?
Depending on cause, treatment may include nasal therapy, oral appliances, CPAP therapy, minimally invasive procedures, or tonsil/adenoid surgery.
Struggling with loud snoring or possible sleep apnea?
Untreated snoring can significantly affect energy, mood, and long-term health. Early evaluation helps identify whether your symptoms are due to nasal, throat, or airway obstruction.
