Fact Checked

Intus Healthcare’s writers, customer service team, and sleep experts review and ensure this information is accurate.

Although extremely uncommon, it is possible to die from untreated Obstructive Sleep Apnoea. Research has found that OSA increases a person’s risk of sudden death (1). The risk can be higher in older people, those with a critical illness, and people with severe OSA.

Untreated Sleep Apnoea significantly increases the risk of death because it can lead to cardiovascular conditions that can be fatal. One study found that people with severe Sleep Apnoea were up to three times more likely to die prematurely if untreated (2).

There is no doubt that Sleep Apnoea can severely affect your quality of life. Treatment is therefore essential not only to improve your day-to-day existence but to avoid the onset of more serious, life-threatening conditions.

 

Untreated Sleep Apnoea Life Expectancy

Untreated Obstructive Sleep Apnoea can significantly reduce your life span. Those with untreated OSA are at more than three times the risk of premature death, reducing life expectancy by 17% (3). A study found that those with Sleep Apnoea who did not seek treatment had a five times greater chance of heart-related death (2).

 

Why can you die from Sleep Apnoea?

 

Obstructive Sleep Apnoea

Obstructive Sleep Apnoea (OSA) is when your airways become partially or fully blocked during sleep. This blockage causes breathing pauses (Apnoea events) that can happen more than 30 times per hour per night. Choking in your sleep, waking up gasping for air, and snoring are common symptoms of Sleep Apnoea.

The breathing pauses can last at least 10 seconds and cause the body’s oxygen levels to fall, carbon dioxide levels to rise, and blood pressure and heart rate spikes. As the body struggles to breathe, hormones like cortisol (the “stress hormone”) increase. Typically, it is not Sleep Apnoea alone that will kill you but the development of other health conditions when it is left untreated.

 

Health Conditions Caused by Sleep Apnoea

Up to 2.5 million people with Sleep Apnoea are unaware they have it, and the frequent pauses in breathing throughout the night can lead to other health risks (3). Treating OSA is crucial in preventing the development of long-term conditions, such as:

Research shows that it does not matter the age, gender or BMI of those with untreated breathing disorders (OSA) – the mortality risk remains high (4). Repeated cycles of accelerated heart rate and increased blood pressure occur due to the continuous closing of the airway.

This can contribute to plaque build-up in the arteries (called atherosclerosis), which strains the cardiovascular system and increases the risk of heart attack, stroke and heart disease. Heart disease includes atrial fibrillation, heart attack, and heart failure.

Sleep Apnoea can also cause type 2 diabetes as it alters glucose metabolism and promotes insulin resistance. The risk of developing pre-diabetes, known as metabolic syndrome (which includes abnormal cholesterol levels, high blood pressure, elevated blood sugar, and excess body fat), is also increased with OSA.

Star Wars actress Carrie Fisher sadly died from severe Sleep Apnoea and heart disease (5).

 

Cognitive and Mental Health Complications

Sleep Apnoea not only affects one’s physical health but also has significant implications for cognitive and mental well-being. The disruptions in normal sleep patterns caused by Sleep Apnoea can lead to a range of complications, including:

 

Dangers of Driving with Untreated Sleep Apnoea

Sleep Apnoea causes daytime fatigue due to the lack of sleep, increasing fatalities at the wheel. Data from the AA shows that 13% of UK drivers admit to falling asleep at the wheel, and up to 25% of fatal accidents are caused by drivers who have fallen asleep at the wheel (6).

The British Snoring & Sleep Apnoea Association reported around 300 people are killed yearly because a driver has fallen asleep at the wheel. 40% of sleep-related accidents involve commercial vehicles (7). It is estimated that there are 50,000 lorry drivers in the UK, and 15% of them have OSA (7).

If you are diagnosed with OSA, it is vital that the DVLA be informed.

Can Sleep Apnoea Be Cured?

No, Sleep Apnoea cannot be cured; however, it can be treated, and symptoms managed.

 

Treating Sleep Apnoea

The sooner OSA is treated, the less likely other health conditions will develop. Sleep Apnoea is almost always treatable, and combined with good sleep hygiene, you should return to getting quality sleep again.

The most effective treatment option is CPAP therapy, which consists of a CPAP machine providing pressurised air into the airway through a mask. However, you can make some lifestyle changes to minimise the symptoms. These include:
