Sleep apnoea symptoms and risks
Sleep apnoea is a serious sleep disorder that can increase your risk of developing other chronic and life-threatening conditions. The good news is that sleep apnoea is treatable. Finding out if you’re at risk is the first step toward improving your health.
Health risks of untreated sleep apnoea
Clinical studies show that people with untreated sleep apnoea have a higher risk of suffering serious health problems:
- High blood pressure
As many as 1 in 3 people with high blood pressure also have sleep apnoea.
43% of people with mild sleep apnoea & 69% of people with severe sleep apnoea have high blood pressure.1
- Heart disease
Sleep apnoea may place you at higher risk for heart disease and stroke.
Up to 76% of people with stable heart failure also have sleep apnoea.2
- Type 2 diabetes
Nearly 1 in 2 people with Type 2 diabetes also suffer from sleep apnoea.3
Studies show that sleep apnoea may affect the body’s ability to use glucose and insulin.
Sleep apnoea is strongly linked with hypertension, regardless of other risk factors.
83% of people with drug-resistant hypertension also have sleep apnoea.4
Multiple studies have shown that people with sleep apnoea are at a higher risk of having a stroke.
Among people with recent strokes, more than 70% had sleep apnoea.5
Treating sleep apnoea can increase daytime energy levels and give you more energy to exercise, which can lead to weight loss.
77% of obese people also have sleep apnoea.6
Sleep apnoea increases the risk of motor vehicle accidents
Did you know that people with sleep apnoea are up to 5 times more likely than normal sleepers to have traffic accidents?7
A study by the American Academy of Sleep Medicine found that obstructive sleep apnoea is associated with an increased risk of motor vehicle accidents. However, when sleep apnoea is treated with effective CPAP therapy the risk is reduced.
Who is at risk of sleep apnoea?
Sleep apnoea can affect anyone, including children. If you have obstructive sleep apnoea, you’re definitely not alone. According to the latest scientific research8, more than 936 million people around the world are affected. This remarkable figure, which was published in the world’s leading respiratory health journal, is nearly 10 times greater than the World Health Organisation’s 2007 estimate of over 100 million.
It is estimated that around 85% of sufferers are not diagnosed8 and, as a result, are not receiving potentially life-changing treatment. There are also a number of significant gender-related differences in the symptoms, diagnosis, consequences and treatment of OSA.
You’re more likely to develop sleep apnoea if you are:
- Overweight or obese, especially if you have a large neck circumference9
- Of advancing years of age1
- A man or a post-menopausal woman10
- Taking sedatives, such as sleeping tablets or tranquilisers13
- A smoker or you drink alcohol in the evening12
- Closely related to people with a history of sleep apnoea13
- Have nasal congestion or certain physical characteristics, like a narrow airway or large tongue14
