Sleep apnea is a sleep disorder that affects your breathing while you sleep, causing it to stop and start. This can prevent your body from getting enough oxygen and interrupt your sleep cycle. Sleep apnea can be caused by an obstruction of the airway, or because the brain fails to send signals to the muscles needed to breathe. It can lead to serious health issues if left untreated, including heart problems, high blood pressure, and an increased risk of stroke and type 2 diabetes.

What You'll Learn
Obstructive sleep apnea (OSA)
OSA is the most prevalent form of sleep apnea, affecting an estimated one billion people worldwide between the ages of 30 and 69. The condition can manifest in a variety of symptoms, including loud snoring, gasping for air, and excessive daytime sleepiness. It can also lead to more severe problems, such as heart issues, high blood pressure, and an increased risk of stroke and heart attack.
The diagnosis of OSA typically involves a sleep study, which may be conducted at a specialist sleep clinic. During the study, individuals are monitored for breathing and heartbeat irregularities while asleep. The severity of OSA is determined by the apnea/hypopnea index (AHI), which quantifies the average number of apnea and hypopnea events per hour.
Treatment options for OSA aim to alleviate symptoms and prevent complications. Lifestyle changes, such as weight loss, smoking cessation, and reduced alcohol consumption, are often recommended as initial interventions. In more severe cases, continuous positive air pressure (CPAP) machines are utilised to deliver pressurised air through a mask, ensuring the airway remains open during sleep. Additionally, mandibular advancement devices, which resemble gum shields, can be used to hold the airways open. In certain situations, surgery may be recommended to address the underlying causes of OSA.
OSA can have significant implications for overall health and daily functioning. It is important to seek medical advice and adhere to treatment plans to effectively manage OSA and minimise associated risks.

Central sleep apnea (CSA)
Sleep apnea is a condition that affects your breathing while you sleep, preventing you from getting restful sleep. This can have a detrimental impact on your physical and mental health. The most common type is obstructive sleep apnea (OSA), caused by a blockage of the airway when the muscles in your throat relax, causing the surrounding tissue to press on your windpipe.
CSA is often associated with a reduction in blood oxygen saturation. It is usually caused by an instability in the body's feedback mechanisms that control respiration. The condition can be an indicator of other issues, such as Arnold-Chiari malformation. In healthy individuals, breathing during sleep is regular, maintaining fairly constant oxygen and carbon dioxide levels in the bloodstream. After exhalation, oxygen levels decrease, and carbon dioxide levels increase. Fresh air is necessary to replenish oxygen and remove carbon dioxide from the bloodstream. Oxygen and carbon dioxide receptors (chemoreceptors) send nerve impulses to the brain, which then signals the reflexive opening of the larynx.
CSA can be diagnosed through polysomnography, which reveals the correlation between the absence of respiratory efforts and the cessation of airflow. Primary CSA is characterised by symptoms such as excessive daytime sleepiness, frequent arousals, insomnia, awakening short of breath, snoring, and witness apnoeas. CSA is also associated with atrial fibrillation, congestive heart failure, and neurological disorders.
Treatment options for CSA include addressing medication that may be causing the condition (such as opioids) by reducing dosage or withdrawal. The FDA has approved a device called the remedē System for moderate to severe CSA, which stimulates a nerve in the chest to send signals to the diaphragm, helping to restore normal breathing patterns. Lifestyle changes, such as losing weight, quitting smoking, and reducing alcohol consumption, can also help manage CSA.

Sleep apnea symptoms
Sleep apnea is a condition that affects your breathing while you sleep, preventing restful sleep and potentially causing physical and mental health issues. The most common symptoms of sleep apnea are interrupted breathing patterns and excessive daytime sleepiness. Interrupted breathing can manifest as fast breathing that gets deeper, then shallower, until it stops, before the pattern starts again. This can occur hundreds of times a night and may be noticed by a bed partner before the patient themselves.
The condition can cause unusual breathing patterns, such as fast breathing that gets deeper, then shallower, until it stops, and then the pattern starts again. Sleep apnea can also cause central sleep apnea, where the brain doesn't send signals to keep breathing-related muscles working while asleep. This can put stress on the heart, which may be life-threatening if left untreated. Sleep apnea can also lead to excessive daytime sleepiness, which may cause accidents or impair work performance and academic achievement.
Sleep apnea can be difficult to self-diagnose, so it is recommended to ask someone to observe you while you sleep to check for symptoms. If you or someone you know may have sleep apnea, it is important to see a healthcare provider, who can help diagnose and create a treatment plan to manage symptoms and prevent complications. Diagnosis is typically based on sleep history and an overnight sleep study, which measures brain activity, eye movements, muscle activity, heart rate, breathing patterns, air flow, and blood oxygen levels.
There are several treatment options for sleep apnea, including lifestyle changes such as weight loss, smoking cessation, and reducing alcohol intake. Many people also benefit from using a CPAP machine, which gently pumps air into a mask worn over the mouth or nose while sleeping, preventing upper airway tissues from collapsing. Mandibular advancement devices are another option, which are dental appliances that prevent the tongue from blocking the throat or advance the lower jaw forward to keep the airway open. In more severe cases, surgery may be recommended to remove or reduce excess tissue obstructing airflow.

Sleep apnea causes
Sleep apnea is a common sleep disorder that causes repeated pauses in breathing during sleep. The two main types of sleep apnea are obstructive sleep apnea (OSA) and central sleep apnea (CSA). The causes of sleep apnea vary depending on the type.
Obstructive Sleep Apnea (OSA) Causes
OSA occurs when the airway becomes blocked or narrowed during sleep, leading to breathing disruptions. This can be caused by various factors, including:
- Obesity or increased fat deposits in the neck, which can narrow or block the airway.
- Enlarged tonsils or adenoids, which can obstruct airflow.
- Large neck or tongue, which can narrow the airway or cause the tongue to fall back and block the airway.
- Hormone changes or endocrine disorders, which can affect the size and shape of the upper airway.
- Certain medications or surgeries can cause complications with OSA due to their impact on breathing.
- Lifestyle factors such as alcohol consumption and smoking can increase the risk of OSA by relaxing the muscles involved in breathing or causing inflammation in the upper airway.
- Age: The risk of OSA increases as people get older.
- Family history and genetics: OSA can be inherited, and certain genetic conditions can raise the risk.
Central Sleep Apnea (CSA) Causes
CSA arises due to problems with the brain's control of breathing during sleep. Specifically, CSA occurs when the brain fails to send the necessary signals to breathe, often due to issues with how the brain stem recognises carbon dioxide levels in the body. Causes of CSA include:
- Heart or kidney failure: These conditions can lead to fluid buildup in the neck, which can obstruct the upper airway.
- Neurotransmitter disorders: These can affect the brain's control of breathing.
- Opioid use disorder or long-term opioid usage: These can interfere with the brain's control of breathing during sleep.
- Other health conditions: Certain conditions, such as heart failure, stroke, amyotrophic lateral sclerosis, and myasthenia gravis, can affect how the brain controls the airways and chest muscles.
- Lifestyle factors: Similar to OSA, alcohol consumption and smoking can increase the risk of CSA by impacting the brain's control of sleep and breathing.
- Age: As people get older, normal changes in how the brain controls breathing during sleep can raise the risk of CSA.

Sleep apnea treatments
Sleep apnea is a common disorder that causes breathing to stop or become very shallow during sleep. This can happen multiple times a night, with pauses lasting from a few seconds to a few minutes. The most common type is obstructive sleep apnea (OSA), which occurs when the upper airway becomes blocked during sleep. This can reduce or completely stop airflow, and people with OSA often snore loudly.
There are several treatment options available for sleep apnea:
Lifestyle Changes
Healthy lifestyle changes can be very effective in treating sleep apnea. These include getting regular physical activity, maintaining healthy sleeping habits, limiting alcohol and caffeine intake, quitting smoking, and maintaining a healthy weight. Sleeping on your side rather than your back can also help to keep your airway open during sleep.
Mouth Devices
Oral devices, also called oral appliances, are placed in the mouth to prevent blocked airways while sleeping. These can be custom-fitted to your mouth by a dentist or orthodontist, who will also teach you how to use them for the best results.
PAP Machines
Positive airway pressure (PAP) machines are another common treatment for sleep apnea. The most common type is the continuous positive airway pressure (CPAP) machine, which provides constant air pressure through the mouth and/or nose to keep the airways open during sleep. Other types of PAP machines include bilevel PAP (BPAP) and auto-adjusting PAP (APAP) machines, which deliver different pressures based on inhalation and exhalation or automatically adjust the air pressure during sleep, respectively.
Surgery
If other treatments are unsuccessful, surgery may be recommended to correct the problem causing sleep apnea. One example of a surgical option is a device implanted under the skin that delivers gentle stimulation to keep the airway open during sleep.
Orofacial Therapy
Exercises for the mouth and facial muscles, called orofacial therapy, may also be an effective treatment for sleep apnea. This therapy helps to strengthen and reposition the tongue and muscles that control the lips, tongue, upper airway, and face.

Frequently asked questions
Sleep apnea is a sleep disorder that causes your breathing to pause or become shallow while you sleep. This can be due to a blocked airway (obstructive sleep apnea) or because your brain doesn't send the necessary signals to breathe (central sleep apnea).
Sleep apnea can sometimes be treated by making lifestyle changes such as losing weight, giving up smoking, and reducing alcohol consumption. In other cases, a CPAP machine, which pumps air into a mask worn over the mouth or nose, may be required.
Untreated sleep apnea can lead to serious health issues, including heart problems, high blood pressure, and type 2 diabetes. It can also cause daytime tiredness and put you at twice the risk of sudden death compared to those without the condition.
