Obstructive Sleep Apnoea (OSA)

Looking After Your Health Even When Asleep

Obstructive Sleep Apnoea (OSA) is a common sleep-related breathing condition that causes repeated pauses in breathing during sleep. Because of when it happens, many people with OSA are unaware that it is happening. Often, sleep apnoea symptoms are only first noticed by a partner or family member.

Our team at Fitzwilliam Road Medical Centre may help assess your symptoms, discuss possible risk factors, and guide you on sleep apnoea treatment options.

When To See A Doctor

Consult a healthcare professional if you have, or if your partner notices, the following:

  • Snoring loud enough to disturb your sleep or the sleep of others.
  • Waking up gasping or choking.
  • Pausing in your breathing during sleep.
  • Excessive daytime drowsiness. You may fall asleep while working, watching television, or even driving a vehicle.

What Is Obstructive Sleep Apnoea?

Obstructive sleep apnoea occurs when the muscles at the back of the throat relax too much during sleep, narrowing or blocking the airway. This causes breathing to repeatedly stop and start throughout the night.
Each pause in breathing can last several seconds and may happen many times per hour. These interruptions prevent deep, restorative sleep, even if you are unaware of them.

There are different types of sleep apnoea, including obstructive, central, and complex sleep apnoea. However, obstructive sleep apnoea is the most frequently diagnosed and can affect people of all ages, though it becomes more common as we get older.

How Common Is Sleep Apnoea in Australia?

Obstructive Sleep Apnoea is a recognised health concern in Australia. Although estimates vary depending on how it’s measured, research from Sleep Help Foundation mentioned that around 8.3% of Australian adults have been diagnosed with OSA.

This figure highlights both the prevalence of OSA and the importance of seeking assessment for symptoms, especially if they interfere with sleep quality or daytime function.

How Obstructive Sleep Apnoea Can Affect Your Health and Daily Life

OSA not only disrupts sleep but may also place ongoing strain on the body and affect how you feel and function during the day.
Over time, OSA may be associated with an increased risk of:

  • High blood pressure
  • Heart disease and stroke
  • Type 2 diabetes
  • Difficulty concentrating and memory problems
  • Mood changes, including irritability
  • Ongoing daytime tiredness and fatigue


Excessive sleepiness during the day can also increase the risk of workplace incidents or driving accidents, particularly when alertness is reduced.

Risk Factor of OSA

Several factors may increase the likelihood of developing OSA, including:

General factors

  • Male gender
  • Post-menopausal women
  • Age over 50 years


Metabolic and lifestyle factors

  • Overweight or obesity
  • Insulin resistance or type 2 diabetes
  • Excess alcohol consumption
  • Use of sedative medications or opioids
  • Smoking

Sleep and anatomical factors

  • Sleeping on the back (supine position)
  • Enlarged tonsils
  • Nasal obstruction
  • Jaw or facial structure differences (such as a smaller or recessed jaw)
  • Genetic factors affecting jaw shape


Medical conditions

  • Thyroid disease
  • Neuromuscular conditions


Having one or more risk factors does not mean you have sleep apnoea, but it may increase the need for assessment if symptoms are present.

Take the Next Step Toward Better Sleep

Living with ongoing tiredness, loud snoring, or disrupted sleep can quietly affect your health, focus, and quality of life. Obstructive Sleep Apnoea is a common condition, and support is available.

If you have noticed symptoms in yourself, or if someone close to you has raised concerns about your sleep, a conversation with your GP is a practical first step to clarify what may be contributing to your symptoms and whether assessment or sleep apnoea treatment options should be considered.
