Sleep apnoea is a serious sleep disorder that affects millions of people worldwide, yet many remain undiagnosed. Characterised by repeated pauses in breathing during sleep, it can lead to poor sleep quality, daytime fatigue, and long-term health complications. Research from the https://www.verywell-uk.co.uk/ highlights that around 1 in 5 adults experience some form of obstructive sleep apnoea (OSA), with men being nearly twice as likely to be affected as women. Untreated, it can increase the risk of high blood pressure, heart disease, and even stroke.
The condition arises primarily when the muscles in the throat relax excessively during sleep, blocking the airway. Central sleep apnoea, another type, occurs when the brain fails to signal the muscles to breathe properly. The most common triggers include obesity, large neck circumference, nasal congestion, and smoking. Smoking, in particular, is linked to a 30% increased risk of developing OSA, as it inflames the airways and reduces oxygen levels.
Symptoms often go unnoticed until they manifest during daytime. Common signs include loud snoring, gasping or choking during sleep, morning headaches, and persistent fatigue. Many people dismiss these as normal ageing or stress, delaying treatment. However, early intervention is crucial. Studies show that untreated OSA can shorten lifespan by up to 12 years, underscoring the importance of regular sleep assessments.
A balanced approach to diagnosis involves a combination of sleep studies (polysomnography) and questionnaires assessing breathing patterns. The gold standard is an overnight sleep test at a dedicated clinic, where sensors monitor breathing, heart rate, and oxygen levels. At-home sleep tests are also available, offering a more convenient option for some individuals.
Treatment options vary depending on the severity of the condition. Mild cases may respond well to lifestyle changes, such as weight loss, avoiding alcohol before bed, and using nasal strips to keep airways open. For moderate to severe cases, continuous positive airway pressure (CPAP) therapy is the most effective treatment. CPAP machines deliver a steady stream of air pressure to prevent airway collapse, with studies showing it reduces apnoea events by up to 70% in many patients.
However, adherence remains a challenge. Research indicates that only about 40% of patients with OSA use their CPAP machines consistently. Addressing this issue often requires behavioural support, such as regular check-ins with healthcare providers and customised treatment plans. Alternative therapies, like oral appliances (mandibular advancement devices), can also help by repositioning the jaw to keep airways open.
For those with central sleep apnoea, medications or devices like bilevel positive airway pressure (BiPAP) may be recommended. In rare cases, surgical interventions—such as uvulopalatopharyngoplasty (UPPP)—are considered, though they carry risks and are typically reserved for severe cases that don’t respond to other treatments.
- Approximately 18 million adults in the UK have sleep apnoea, yet only about 1 in 10 are diagnosed.
- Obesity is the leading risk factor, with a body mass index (BMI) above 30 doubling the likelihood of developing OSA.
- Smoking increases the risk by 30%, while quitting can reduce it by up to 50% within a year.
- CPAP therapy reduces apnoea events by an average of 60-70% in treated patients.
- Central sleep apnoea is most common in older adults and those with heart conditions.
Early diagnosis and consistent treatment are key to managing sleep apnoea effectively. By addressing the underlying causes and adopting a personalised approach, individuals can improve sleep quality, reduce health risks, and enhance overall well-being. If you suspect you may have sleep apnoea, consulting a specialist is the first step towards a healthier, more restful night’s sleep.
