How Is Sleep Apnea Diagnosed in Malaysia?
Sleep apnea is usually diagnosed by combining a patient’s symptoms, physical examination, airway assessment and a sleep study. In Malaysia, patients with loud snoring, witnessed breathing pauses during sleep, choking or gasping at night, morning headache, daytime sleepiness or poor sleep quality may be advised to undergo further assessment for obstructive sleep apnea.
Dr Cheong ENT Clinic provides ENT assessment for snoring and suspected obstructive sleep apnea at KPJ Pasir Gudang Specialist Hospital in Johor. ENT assessment helps check for possible upper airway factors such as blocked nose, deviated nasal septum, turbinate swelling, enlarged tonsils or throat narrowing.
Common symptoms that may suggest sleep apnea
Common symptoms of obstructive sleep apnea include loud snoring, witnessed pauses in breathing during sleep, choking or gasping at night, restless sleep, morning headache, dry mouth, daytime tiredness, poor concentration and waking up unrefreshed.
Some patients may not realise they have breathing pauses during sleep. Often, the concern is first noticed by a spouse or family member.
Clinical assessment and screening
The first step is usually a medical consultation. The doctor will ask about snoring, breathing pauses, daytime sleepiness, sleep quality, weight, nasal blockage, tonsil size, medical conditions and medication history.
Screening questionnaires such as STOP-Bang or Epworth Sleepiness Scale may be used to estimate risk. These tools can support assessment, but they do not replace a sleep study for diagnosis.
ENT airway assessment
For patients with snoring or suspected obstructive sleep apnea, ENT assessment may look for airway factors that contribute to poor airflow during sleep.
This may include examination of the nose, mouth, throat, tonsils, soft palate and neck. Nasal endoscopy may be performed when clinically needed to assess nasal blockage, deviated septum, turbinate swelling, nasal polyps, post-nasal drip or upper airway narrowing.
Sleep study test
A sleep study is the main test used to diagnose obstructive sleep apnea. It records breathing, oxygen level and sleep-related events during sleep.
Depending on the patient’s condition and available facility, the sleep study may be done as a home sleep apnea test or as an overnight polysomnography test in a sleep laboratory.
A polysomnogram is a sleep study used to assess sleep disorders, especially obstructive sleep apnea and snoring-related problems. Malaysian hospital sleep centres describe PSG as an overnight test that monitors sleep and breathing patterns.
Home sleep apnea test vs polysomnography
A home sleep apnea test is usually more convenient and may be suitable for selected adults with suspected obstructive sleep apnea. It is commonly used to measure breathing pattern, oxygen level, pulse rate and snoring-related parameters during sleep.
Polysomnography, also called PSG, is a more detailed overnight sleep study usually performed in a sleep laboratory. It can record more information, including sleep stages, breathing, oxygen level, heart rhythm, body movement and other sleep-related signals.
The choice of test depends on the patient’s symptoms, medical condition, risk level and the doctor’s recommendation.
Understanding AHI and sleep apnea severity
Sleep study results usually include an Apnea-Hypopnea Index, or AHI. AHI estimates how many breathing pauses or shallow breathing events occur per hour of sleep.
The doctor will interpret the sleep study result together with the patient’s symptoms, oxygen level, medical conditions and airway findings before advising treatment.
After diagnosis: what happens next?
Treatment depends on the severity of sleep apnea and the likely contributing factors. Options may include weight management, sleep position advice, treatment of nasal allergy or blocked nose, CPAP therapy, oral appliance discussion, or surgery in selected patients.
ENT assessment is useful when snoring or sleep apnea may be related to nasal blockage, enlarged tonsils, throat narrowing or other upper airway factors.
FAQ section
How is sleep apnea diagnosed in Malaysia?
Sleep apnea is diagnosed using symptoms, clinical assessment, physical examination and a sleep study. The sleep study may be a home sleep apnea test or an overnight polysomnography test, depending on the patient’s condition and the doctor’s recommendation.
Do I need a sleep study to confirm sleep apnea?
Yes. Symptoms and screening questionnaires can suggest the risk of obstructive sleep apnea, but a sleep study is usually needed to confirm the diagnosis and assess severity.
Can an ENT specialist diagnose sleep apnea?
An ENT specialist can assess snoring, nasal blockage, tonsils and upper airway factors that may contribute to obstructive sleep apnea. A sleep study is usually needed to confirm the diagnosis and guide treatment.
What is a home sleep apnea test?
A home sleep apnea test is a sleep test done at home using portable monitoring equipment. It may record breathing pattern, oxygen level, pulse rate and snoring-related parameters during sleep.
What is polysomnography?
Polysomnography, or PSG, is an overnight sleep study usually performed in a sleep laboratory. It records sleep and breathing-related signals to assess sleep apnea and other sleep disorders.
