What is Obstructive Sleep Apnoea (OSA)?

During normal sleep, air travels freely to and from your lungs through your airways. However, in obstructive sleep apnoea, the soft tissues in the airway collapse, stopping the passage of air to your lungs and disturbing your sleep. When this obstruction occurs a person is likely to snore, though it is important to note that not all individuals with OSA show symptoms of snoring.

OSA is associated with :

Nighttime symptoms (usually noted by partner)

  • Loud persistent snoring
  • Witnessed pauses in breathing
  • Choking or gasping for air
  • Restless sleep
  • Frequent visit to the bathroom

Daytime symptoms

  • Early morning headache
  • Daytime sleepiness
  • Poor concentration
  • Irritability
  • Falling asleep during routine activities

If left untreated it may increase the risk of long term consequences, such as

  • High blood pressure
  • Type 2 diabetes
  • Abnormal heart rhythm
  • Heart failure
  • Stroke


The probability that you have OSA can be assessed using simple screening methods. However, an overnight diagnostic test will be necessary to confirm the diagnosis and evaluate the severity. This test can be carried out at home or in the hospital sleep lab. Treatment Continuous Positive Airway Pressure (CPAP) is the recommended treatment for OSA. CPAP acts as an airway splint and prevents the
upper airway collapsing during sleep. The obstruction is prevented by providing a flow of air through your nose/face using a mask. Regular CPAP therapy may reduce the health consequences of OSA.

At Mediclinic City hospital we have the facilities to screen, diagnose and treat OSA. If you feel you have any of the above symptoms you need to see your doctor to discuss the possibility of Obstructive Sleep Apnoea.
