WHAT IS SLEEP APNEA?
Sleep Apnea is a serious medical condition which effects your quality of sleep, health and general wellbeing. An apnea is the interuption of airflow to your lungs, caused buy the relaxed state of the walls and muscels in your airway forming a blockage during sleep. Apneas can occur hundreds of times a night and can last up to a minute during which your body is being deprived of oxygen.

DON'T IGNORE THE SNORE!
NOT EVERONE WHO SNORES HAS SLEEP APNEA, BUT NEARLY EVERYONE WHO HAS SLEEP APNEA SNORES.
Sleep Apnea is not just snoring or feeling tired during the day, it is actually a serious medical condition that if left untreated can have devistating effects on your health and quality of life.
Obstructive Sleep Apnea (OSA) and is the most common form of Sleep Apnea. OSA occurs when the walls and muscles of the upper airway (including the tongue, soft palate etc) relax in such a way that they collapse and block the airway during sleep. The subsequent interruption of air supply to the lungs is called an apnea.
ASSOCIATED HEALTH RISKS OF SLEEP APNEA
People with Sleep Apnea are 3 times more likely to suffer a stroke. Almost 70% of people who have had a stroke have Sleep Apnea.1
People with Sleep Apnea are 3 times more likely to suffer a work-related injury or fatalities.9
77% of people who are obese (Body Mass Index greater than 30) may have Sleep Apnea.6
TYPE 2 DIABETES
58% of patients with Type 2 Diabetes may have Sleep Apnea.5
People with Sleep Apnea may have an increased risk of suffering a heart attack.2
Sleep Apnea doubles the risk of developing depression.7
HIGH BLOOD PRESSURE
50% of people with high blood pressure also may have Sleep Apnea and Sleep Apnea is a common cause of high blood pressure.3 Patients on multiple medications to manage their blood pressure have an 83% chance of having Sleep Apnea.4
MOTOR VEHICLE ACCIDENTS
People with Sleep Apnea are 7 times more likely to have a motor vehicle accident.8

HOW MANY PEOPLE HAVE SLEEP APNEA?
Obstructive Sleep Apnea (OSA) is the most common type of Sleep Apnea.
1 in 4 Australians suffer from this condition.3
The table shows the percentage of Australians who have the condition by age group. As you can see, it affects far more men than women.
Based on a patient base of 78,145 across Australia, the Independent Sleep Physician Cohort (ISPC) shows how instances of Sleep Apnea can increase along with common risk factors. The patients in the sample were assessed for eligibility for a sleep test according to criteria set by the ISPC.
Out of 78,145 patients tested, 86% of patients who were obese had sleep apnea, compared to 60% who were in a healthy weight range (BMI between 18.5 – 24.5).
The chances of having sleep apnea also increased with other common risk factors:
84% of males tested had sleep apnea
88% of males, over 45 tested had sleep apnea
92% of males, over 45, who were overweight and obese had sleep apnea.1
If you treat your Sleep Apnea you may decrease your risk of suffering a cardiovascular event (stroke or heart attack) by 64% if diagnosed and treated early,2 along with improving an array of other health and lifestyle benefits.
45-55 YEARS 11% 2.5%
55 YEARS AND OLDER 24% 6%

ARE YOU AT RISK?
BMI > 30
AGED > 50
The following risk factors indicate whether you could be at risk of developing, or already have, Sleep Apnea.
Being middle-aged and overweight are the most common risk factors – feeling motivated to act can be a challenge for those who feel tired. Don’t delay being tested – it could be the first step in turning your life around.
Other factors include:
Age (the older you get, the more likely you are to have Sleep Apnea)
A large neck circumference (greater than 43cm in men and 40cm in women)
Narrow upper airway (due to comparatively large tongue or uvula)
Large tonsils or adenoids
Consumption of alcohol or use of sedatives (which may relax your throat muscles)
80% of people with Sleep Apnea are undiagnosed and remain at risk3
