Experiencing breathing difficulties during sleep can be a symptom of a serious health condition known as sleep apnea. Sleep apnea is a common disorder that causes the airways to collapse or become blocked while asleep, resulting in multiple breathing pauses throughout the night. It can lead to severe complications, including high blood pressure, heart disease, and diabetes. If you or someone you know exhibits symptoms of sleep apnea, it is important to consult a healthcare provider for a proper diagnosis and treatment plan.

Sleep apnea: a condition that affects your breathing while you sleep
Sleep apnea is a common condition that affects your breathing while you sleep. It occurs when your breathing stops and restarts multiple times during sleep. This interruption can prevent your body from receiving sufficient oxygen and cause you to wake up briefly. These repeated awakenings disrupt your sleep, leading to daytime tiredness and a higher risk of accidents. Sleep apnea can also increase the likelihood of developing serious health issues, such as high blood pressure, heart disease, and stroke.
There are two primary types of sleep apnea: obstructive sleep apnea (OSA) and central sleep apnea. OSA, the more prevalent type, occurs when the upper airway becomes blocked during sleep due to factors such as obesity, enlarged tonsils, or changes in hormone levels. This blockage can significantly reduce or even stop airflow, requiring your diaphragm and chest muscles to work harder to open your airways.
Central sleep apnea, on the other hand, is caused by issues in the brain's respiratory control center, which fails to send the necessary signals to breathe. This type often affects individuals with neuromuscular diseases, such as amyotrophic lateral sclerosis (ALS), or those who have experienced a stroke. In some cases, opioid use or age-related changes can also contribute to central sleep apnea.
Additionally, there is a less common form called complex sleep apnea syndrome, where an individual experiences a combination of obstructive and central sleep apnea. This occurs when someone with obstructive sleep apnea develops central sleep apnea after receiving treatment for the former condition.
If you or someone you know exhibits symptoms of sleep apnea, it is important to consult a healthcare provider. Diagnosis of sleep apnea typically involves a sleep study, which can be conducted in a specialized lab or at home. Treatment options include breathing devices like continuous positive air pressure (CPAP) machines and, in some cases, surgery to correct the underlying problem.

Orthopnea: difficulty breathing when lying down, usually caused by an underlying condition
Experiencing shortness of breath when lying down to sleep could be a symptom of orthopnea. Orthopnea is a condition where one feels like they are unable to breathe or are short of breath when lying down. This can occur when lying down to sleep or during other activities such as watching TV. The feeling of breathlessness improves when one sits or stands up. Orthopnea is caused by an underlying medical condition affecting the heart or lungs.
If you are experiencing orthopnea, it is important to consult a healthcare provider. A healthcare professional can help identify and treat the underlying condition causing orthopnea, making it easier to breathe while lying down.
Other causes of difficulty breathing during sleep include sleep apnea and restless leg syndrome. Sleep apnea is a condition where an individual stops breathing while asleep due to a blockage in the airway or the brain not controlling breathing as expected. This can cause the individual to wake up gasping for air, disrupting their sleep. Obstructive sleep apnea occurs when the tongue and other tissues in the mouth block the airway when lying down. Central sleep apnea occurs when the brain fails to send signals to keep breathing-related muscles working during sleep.
Restless leg syndrome (RLS) is another possible cause of sleep disruption. RLS causes unpleasant sensations in the legs and an urge to move them, resulting in fragmented sleep.
If you are experiencing difficulty breathing while lying down or any other sleep disruptions, it is recommended to consult a healthcare professional for proper diagnosis and treatment.

Obstructive sleep apnea: when airways collapse or become blocked
Obstructive sleep apnea (OSA) is a condition where sleep is interrupted by abnormal breathing. This occurs when the airway is blocked, causing a reduction in airflow of at least 30% for more than 10 seconds, and happening at least 5 times an hour. When breathing is reduced, it is called hypopnea, and when it completely stops, it is called apnea. OSA can range from mild to severe, with severe OSA classified as having an AHI (apnea-hypopnea index) greater than 30, meaning more than 30 episodes per hour. Moderate OSA has an AHI between 15 and 30, while mild OSA has an AHI between 5 and 15.
OSA is characterised by episodes of complete (apnea) or partial (hypopnea) collapse of the upper airway, leading to decreased oxygen levels or arousal from sleep. These episodes can recur hundreds of times a night, causing fragmented and non-restorative sleep. OSA is often associated with snoring, and as snoring gets louder, the chances of having OSA increase. Bed partners may notice that snoring is interrupted by pauses in breathing, which are apnea episodes.
Risk factors for OSA include a large or thick neck (greater than 16 inches for women and 17 inches for men), and it is more common in middle-aged and older adults, as well as in men compared to women. However, anyone at any age can develop OSA, and many people with OSA may not know they have it.
Treatments for OSA aim to keep breathing consistent and stop or reduce apnea episodes. These include the use of a CPAP (continuous positive airway pressure) machine and mask, which provide a constant flow of air to keep the airway open. Oral appliances, such as custom-fit mouthpieces, can also be used to keep airways open during sleep. In some cases, surgery may be recommended, such as the removal of adenoids and tonsils, particularly in children. Implanting nerve stimulators can also help strengthen muscles and prevent airway collapse during sleep. Lifestyle changes, such as sleeping on the side instead of the back and avoiding alcohol, can also help manage OSA.

Central sleep apnea: when the brain stops sending signals to regulate breathing
There are numerous reasons why someone might struggle to breathe during sleep. One possible explanation is central sleep apnea, a sleep disorder characterised by disrupted breathing during sleep. People with central sleep apnea experience episodes of disrupted breathing at night, where their breathing stops and starts repeatedly. This is because the brain temporarily stops sending signals to the muscles that control breathing.
Central sleep apnea is often a complication of other conditions, such as heart failure, atrial fibrillation, stroke, or brainstem problems. It can also be caused by certain medications, such as opioid painkillers. The condition can be diagnosed through a sleep study, where healthcare professionals monitor brain waves, heartbeats, and breathing patterns.
Those with central sleep apnea may experience symptoms such as daytime sleepiness, severe morning headaches, irritability, and trouble concentrating. They may also wake up abruptly during the night for no apparent reason and feel restless during sleep. If left untreated, central sleep apnea can increase the risk of developing other diseases, including high blood pressure, heart disease, stroke, diabetes, and headache syndromes.
Treatment options for central sleep apnea include the use of positive air pressure (PAP) systems, such as continuous positive air pressure (CPAP) machines, bilevel positive airway pressure (BiPAP) machines, and adaptive servo-ventilation (ASV) machines. In some cases, the FDA-approved remede System device may be implanted in the chest to stimulate the nerve controlling the breathing muscles when a pause in breathing is detected.

Narcolepsy: a disorder causing people to fall asleep suddenly during the day
Experiencing breathing difficulties during sleep can be a symptom of several underlying conditions. One of the most common is sleep apnea, a condition that affects your breathing while you sleep, causing you to stop breathing for 20 to 30 seconds at a time, numerous times throughout the night. Obstructive sleep apnea (OSA), the most common form of this disorder, occurs when the tongue and other tissues in the mouth fall back and block the airway. Central sleep apnea (CSA), on the other hand, is caused by the brain failing to send signals to keep breathing-related muscles working during sleep.
Another condition that can cause breathing difficulties during sleep is orthopnea, which is characterised by shortness of breath while lying down. This can occur when sleeping or during other activities such as watching TV. Orthopnea is often a symptom of an underlying medical condition affecting the heart or lungs.
Other potential causes of breathing difficulties during sleep include restless leg syndrome, which causes unpleasant sensations and an urge to move the legs, and narcolepsy, a disorder that causes people to fall asleep suddenly during the day, regardless of how much sleep they get at night.
If you are experiencing breathing difficulties while sleeping, it is important to consult a healthcare professional for a proper diagnosis and treatment. A sleep study may be recommended to characterise your breathing patterns and identify any underlying conditions.
Narcolepsy: A Disorder Causing Sudden Daytime Sleep
Narcolepsy is a sleep disorder characterised by excessive daytime sleepiness and uncontrollable episodes of falling asleep during the day. People with narcolepsy may fall asleep suddenly, regardless of the activity they are engaged in or the amount of sleep they have had at night. These daytime sleep episodes can last from a few seconds to several minutes.
Narcolepsy is caused by a problem with the brain's ability to regulate sleep and wakefulness. It is often associated with low levels of hypocretin, a neurotransmitter that promotes wakefulness. This can be due to the immune system mistakenly attacking the cells that produce hypocretin or other genetic or environmental factors.
The main symptom of narcolepsy is excessive daytime sleepiness, but other symptoms can include cataplexy (sudden loss of muscle tone), sleep paralysis (temporary inability to move or speak while falling asleep or upon waking), hallucinations, and disrupted nocturnal sleep.
Treatment for narcolepsy aims to control symptoms and improve quality of life. Medications such as stimulants, selective serotonin reuptake inhibitors (SSRIs), and sodium oxybate may be prescribed to promote wakefulness and improve sleep quality. Behavioural treatments, such as maintaining a regular sleep schedule and taking scheduled naps, can also help manage symptoms.
While narcolepsy cannot be cured, proper management can help those affected lead full and productive lives. It is important to work closely with a healthcare professional to find the most effective treatment plan.
