It is believed that sleep apnoea affects millions of people every year, but since it occurs at night while you sleep, people are unaware they are suffering and thus it goes undiagnosed. Signs and symptoms include:
- unrefreshed sleep
- daytime sleepiness
- morning headaches
- going to the toilet frequently throughout the night
- gagging or gasping for air at times whilst sleeping
- loud snoring is also common
Sleep Apnoea results from the tongue and soft palate collapsing onto the back of the throat while you sleep. This obstructs the upper airway, causing airflow to be restricted or completely stop; often for more than 10 seconds at a time. Your brain signals the body that there is a lack of oxygen and adrenalin is released and you arouse, this is where you may gasp for breath. Your airway will regain tonus and open, forcing the obstruction in your throat to clear and then your breathing will begin again. This is an obstructive apnoea; the process repeats itself over and over again through the night. In severe cases some people can lose breath for as much as 40 seconds over 60 times an hour.
The combination of low oxygen levels and consistent, disturbed, and interrupted sleep can causes the patient to feel exhausted throughout the day, but in some cases the patient does not even know how bad their sleep really is. Thus it is vital that if you have any symptoms you have a sleep study to assess your risk of sleep disordered breathing; as the ill effects of sleep apnoea can contribute to a host of very serious health concerns like cardiovascular disease, stroke and heart attack.
Types of sleep apnoea
- Obstructive sleep apnoea – Is the most common sleep related breathing disorder, where the upper airway repeatedly collapses during sleep. During an obstructive breathing event, someone with OSA continues to breathe but cannot get enough air into the lungs because the upper airway becomes too narrow or closes completely, this is known as an obstructive apnoea. The soft tissue in the back of your throat or tongue base collapses and then obstructs your airway resulting decreased oxygen intake. The brain detects the oxygen deficiency which then leads to multiple momentary arousals to draw breath – profoundly interrupting your deep sleep.
- Central sleep apnoea – Is another condition where your airway does not become blocked, but instead your brain does not send the signal to your muscles to breathe. In this type we may need to refer you to a specialist.
- Mixed apnoea – Is a combination of both central and obstructive Sleep Apnoea. If you have mixed Sleep Apnoea you may experience snoring, but you may find that treatments designed to help airway obstructions will not fully stop apnoeic episodes. Though your brain briefly arouses you in order for you to resume breathing, your sleep is constantly interrupted. This leaves you feeling fatigued the next day.
Who’s at risk?
Those that suffer an increased risk of suffering from sleep Apnoea are males who are moderately to severely overweight, and those over the age of 40. But almost anyone can suffer; even petite women and children. This potentially life threatening disease is a lot more common than generally expected and should be taken very seriously.
What are the signs and symptoms of sleep apnoea?
- Tiredness/fatigue and irritability in the mornings and during the day
- Daytime sleepiness
- Frequently waking throughout the night to go to toilet or get a drink
- Regular Morning Headaches
- Worn teeth caused by clenching or grinding of teeth
- Poor memory
- Reflux problems
- Dark circles or bags under or around the eyes
Why is it so harmful?
Repetitive airway collapse can lead to large pressure fluctuations in the lungs and oxygen deficiency which places stress on the heart and cardiovascular system. Consequently in people with OSA, the risk of high blood pressure, stroke and sudden cardiovascular death during sleep is increased as is diabetes. Most recently, OSA has been associated with an increased risk of cancer death. Thus it is imperative that once diagnosed with OSA you are adequately treated.
But the strains on the system from arousing over and over due to lack of oxygen, as much as 500 times a night; inhibit your body from getting the refreshing sleep it needs. Not only is OSA a major, often unrecognized, cause of daytime sleepiness, it can also be an associated risk factor for very serious medical conditions:
- Heart Disease (33% increase in cardiovascular disease)
- High Blood Pressure
- Immune compromise
- Memory Impairment / loss
- Poor Motor Skills
How do you get diagnosed?
Because sleep Apnoea occurs at night while you should be sleeping deeply, diagnosis isn’t as easy as a quick visit to your local GP or dentist.
There is a couple of options where to have a sleep study. The gold standard is the in-lab hospital sleep study where your sleep will need to be monitored by a trained professional who will also use a series of highly specialised instruments to monitor your body through a night’s sleep. But for those patients who struggle to sleep in strange surroundings, there is a range of in home sleep study options.
We offer you the ability to get tested in the comfort of your own home, the home sleep study monitors you while you sleep in your natural surroundings. You’ll be monitored through the night with specialised sleep therapy equipment in the comfort of your home and bed.
Why should I have a sleep study?
It is imperative that you have a sleep study prior to being fitted with any sort of treatment for sleep disordered breathing. Even if you think you just snore, it is possible that you have some level OSA and may need to see a specialist. Healthcare funds recognise this and will not give any rebate for any treatment of sleep disordered breathing snoring or OSA unless the patient has had a full sleep study which has been analysed by a sleep physician.
At Clifton Hill Dental we will first need to schedule a professional sleep study to properly and legally diagnose your condition as Snoring or Sleep Apnea. You can choose to perform your study in a hospital situation with all the latest technology. But not everyone is suited to undergo a hospital based sleep evaluation and so may elect to schedule an in-home evaluation.

Sleep disorders, if left untreated, can result in a host of serious negative side effects to your overall health and mental well-being.
