Obstructive Sleep Apnoea: More Than Just a Bad Night's Sleep

Sleep apnoea is not just snoring and disrupted sleep, it is a serious medical condition.
People who have obstructive sleep apnoea (OSA) will experience continuous episodes of partial or complete obstruction of the throat while sleeping (Sleep Health Foundation n.d.a).
This obstruction occurs when the walls of the upper airway, including the tongue, relax and block or restrict the airway (Healthy Sleep Solutions n.d.)
A person with OSA will stop breathing for a short period of time. Typically this will last between 10 seconds to one minute (Better Health Channel 2019).
This cycle repeats multiple times during the night. The effect of this is fragmented sleep, causing a person to feel unrefreshed upon waking; daytime tiredness; poor concentration; and general fatigue (Better Health Channel 2019).
Someone with sleep apnoea will:

An estimated five per cent of Australians experience sleep apnoea. Around one in four men over the age of 30 years are affected (Better Health Channel 2019).
OSA interrupts sleep and causes stress on the body (Sleep Health Foundation n.d.a). This stress presents in tachycardia; hypertension; changes in metabolism; reduced liver function; nerve dysfunction; and severe fatigue (Healthy Sleep Solutions n.d.).
Evidence indicates that people who have moderate to severe OSA will have other health problems. This includes higher risk of heart attack; stroke, depression; fatty liver disease; hypertension; and diabetes (Sleep Health Foundation n.d.a; Healthy Sleep Solutions n.d.).
Research suggests that people who have OSA are roughly two and a half times more prone to motor vehicle accidents than those without it (Sleep Health Foundation n.d.a).

Obesity is seen as being the leading cause of sleep apnoea. Other factors include:
(Better Health Channel 2019)
It is necessary to know the cause of sleep apnoea, as no single treatment is applicable for everyone (Sleep Health Foundation n.d.b)
Lifestyle changes are considered to be the first line of treatment for sleep apnoea. Specifically losing weight and reducing alcohol consumption (Better Health Channel 2019).
In addition to lifestyle changes, it is often recommended that patients wear a mask at night that prevents their throat from collapsing. The mask gently transmits increased air pressure to the throat. The term for this is nasal continuous positive airway pressure or CPAP. A person with OSA should work with a health professional to find the mask and machine that works for them (Better Health Channel 2019). CPAP is typically very successful at managing the symptoms and effects of OPA (Sleep Health Foundation n.d.a).
For people with mild to moderate sleep apnoea, a mouthguard or similar apparatus may be useful (Better Health Channel 2019).
In severe cases where other therapies have been unsuccessful, surgery to the palate and base of the tongue might be recommended. This surgery is best undertaken by otolaryngologists, who are specifically trained in sleep-related surgery (Better Health Channel 2019).
If the symptoms of OSA are present: snoring, breathing pauses and sleepiness during the day, a person may want to be checked for OSA. The way this condition is typically diagnosed is by an overnight sleep study (Sleep Health Foundation n.d.a).
