Sleep Apnea

Apnea means absence of breath. Sleep apnea occurs when the airway in the throat collapses during sleep reducing airfow or completely blocking the airway. This disrupts sleep and reduces oxygen supply to vital organs.

It is estimated that as many as 26% of adults aged 30-70 years have obstructive sleep apnea. Contrary to popular belief, sleep apnea patients come in all shapes and sizes, not all sleep apnea sufferers snore, many are not obese or even overweight, and not all of them are male. What many people with sleep apnea have in common is the need for better and more affordable access to treatment. Learn more about sleep apnea below.


Sleep Apnea Signs and Symptoms

Things to know about sleep apnea

Obstructive Sleep Apnea 

Obstructive sleep apnea (OSA) occurs when the airway collapses during sleep. Although the person is making an effort to breathe the airway is blocked and breathing is prevented. 

Central Sleep Apnea 

In Central Sleep Apnea (CSA) there is no obstruction in the airway. CSA is rare and results when the signals from the brain to regulate breathing are disrupted.

Oral Appliances 

(also known as Mandibular Advancement Devices) Oral appliances are indicated for those with mild and moderate obstructive sleep apnea (OSA). They may be also used in people with severe OSA who are unable to tolerate a CPAP machine.

Continuous Positive Airway Pressure


 (or CPAP) is used to treat OSA, and may sometimes be effective in CSA. This is a machine that produces air at a high enough pressure to hold the airways open. There are fixed pressure CPAP machines, and automatic machines that adjust the pressure upwards only when you stop breathing. Some models allow completely different pressures for inhaling and exhaling (BiPAP).

Childhood Sleep and Snoring

You don't often think of children snoring or suffering from sleep apnea, but surprisingly a number do. The condition can be serious and may lead to health problems such as failure to thrive, developmental delay or behavioural problems.


Snoring occurs when air does not flow smoothly through the air passages, or when the soft tissues in your throat vibrate during sleep. Snoring can occur in all age groups, but the largest affected group is the middle aged. Snoring may be associated with long term health problems such as an increased risk of heart attack or stroke.

Related Risks

Sleep apnea and sleep deprivation, whether reduced quantity or disturbed quality, may be a contributing factor in other diseases, such as High Blood Pressure, Heart Disease, Diabetes, Obesity and Nocturia.

Things to Avoid

There are things that can make sleep apnea worse, and even if you are on CPAP treatment, they should be avoided. Alcohol relaxes muscles and may worsen apnea, as may sleeping tablets which depress the drive to breathe. A person’s normal CPAP pressure may be insufficient if the person is under the effects of alcohol or sleeping tablets. Other things that disrupt sleep such as caffeine or late night eating should also be avoided.
