Choking In Sleep: What Are The Risks And Dangers?

what happens when you choke in your sleep

Choking in your sleep can be a frightening experience, and it's important to identify the root cause to address the issue. One of the most common causes of choking during sleep is Obstructive Sleep Apnoea (OSA), a sleep disorder characterised by brief interruptions in breathing due to a partial or complete blockage of the airway. Other causes include acid reflux, post-nasal drip, allergies, sinus problems, tonsillitis, neurological conditions, and anatomical issues in the throat or airway. Treatment options for sleep-related choking vary depending on the underlying condition and can include positional sleep therapy devices, oral appliances, lifestyle modifications, and, in some cases, surgery.

Obstructive Sleep Apnoea (OSA)

Choking in your sleep can be a symptom of a variety of conditions, one of the most common being Obstructive Sleep Apnoea (OSA). OSA is a sleep disorder characterised by brief interruptions in breathing during sleep. It occurs when the walls of the throat relax and narrow or close, blocking the airway and interrupting normal breathing. This can cause breathing to become shallow or stop temporarily, leading to choking. When these pauses in breathing keep happening, they deprive the brain of oxygen, causing a drop in oxygen levels in the blood. This, in turn, triggers a brief awakening, often accompanied by choking, gasping, or snorting as the body responds to the lack of oxygen.

The pattern of repeated awakenings can repeat itself anywhere from 5 to 30 or more times every hour, throughout the night. These disruptions impair the ability to reach deep, restful sleep, resulting in excessive daytime sleepiness. OSA is also associated with long-term risks such as high blood pressure, diabetes, and heart disease. The severity of OSA is determined by the number of breathing pauses per hour of sleep, measured using the apnoea-hypopnoea index (AHI). Mild OSA is classified as 5 to 14 episodes per hour, moderate as 15 to 30, and severe as more than 30.

OSA can be diagnosed through a sleep test, which can be conducted at home or in a sleep clinic. Treatment options are available to manage OSA and reduce its impact on quality of life. These include positional sleep therapy devices, oral appliances, mandibular advancements, and continuous positive airway pressure (CPAP) devices. Lifestyle modifications, such as avoiding sleeping on the back, reducing alcohol intake, and maintaining a healthy diet, can also help. In some cases, surgery may be considered if OSA is caused by a correctable physical problem, such as enlarged tonsillar tissue.

It is important to note that choking in sleep can also be caused by other conditions, such as acid reflux, postnasal drip, allergies, sinus problems, or tonsillitis. If you are experiencing frequent choking in your sleep, it is recommended to seek medical advice for a proper diagnosis and treatment plan.

Gastroesophageal Reflux Disease (GERD)

Choking in your sleep can be a symptom of Gastroesophageal Reflux Disease (GERD). GERD is a chronic digestive disorder where stomach acid flows back into the oesophagus, the tube that connects your throat to your stomach. Normally, a ring of muscles called the Lower Oesophageal Sphincter (LES) acts as a one-way valve, allowing food and liquids to enter the stomach and preventing stomach contents from flowing back into the oesophagus. However, in individuals with GERD, the LES weakens or relaxes abnormally, leading to acid reflux. During sleep, especially when lying flat, the risk of acid reflux and aspiration (inhaling stomach contents into the airway) may increase. This can cause a choking sensation and interrupt sleep.

GERD is characterised by repeated episodes of acid reflux that affect quality of life. It is estimated that up to 20% of the US population has GERD, and it can interfere with everyday life. While occasional acid reflux is normal and typically does not cause health complications, frequent acid reflux can have serious consequences. Chronic acid reflux can cause serious and potentially life-threatening health complications if left untreated.

The symptoms of GERD include heartburn, a burning sensation in the chest or throat, coughing, and choking while sleeping. Not everyone with GERD will experience choking during sleep, and the severity and frequency of symptoms can vary from person to person. However, if you regularly wake up choking, snorting, or gasping, it could be a sign of GERD or another condition such as sleep apnea.

If you suspect you have GERD or are experiencing symptoms, it is important to seek medical advice for a proper diagnosis and treatment plan. Over-the-counter antacids can help alleviate symptoms, but it is recommended to speak to a doctor if symptoms persist. Lifestyle changes, such as avoiding trigger foods, not eating right before bedtime, changing your sleep position, wearing loose-fitting clothing, quitting smoking, and maintaining a healthy weight, can also help reduce the risk of choking on acid reflux while sleeping.

In summary, choking in your sleep can be a symptom of GERD, a chronic condition characterised by repeated episodes of acid reflux. GERD can interfere with sleep and cause various symptoms, including choking. Seeking medical advice, making lifestyle changes, and following a treatment plan can help manage GERD symptoms and improve sleep.

Allergies or sinus problems

Allergies are a leading cause of post-nasal drip. When a person is exposed to allergens like pollen, dust mites, pet dander, or mold, their immune system overreacts, resulting in extra mucus production and issues with drainage due to swelling in the nasal passages. This can lead to a buildup of mucus that drips down the throat, causing choking or coughing.

Sinus problems, such as sinusitis and nasal polyps, can also cause mucus to drip from the nose to the throat during sleep, making choking more likely. In addition, allergies can cause inflammation of the sinuses and nasal passages, leading to blocked noses and throats, which can make it hard to breathe while sleeping and increase the risk of choking or coughing.

Individuals with allergic rhinitis are significantly more likely to suffer from sleep issues. They may experience trouble waking up, daytime fatigue, and morning headaches and sinus pain. There appears to be a correlation between the severity of a person's allergies and the severity of their sleep problems. Allergies can also worsen sleep apnea, a condition characterized by brief interruptions in breathing during sleep, which can lead to choking or gasping for air.

To manage allergies or sinus problems that may be causing choking in your sleep, you can try the following:

  • Use an air purifier to clear your bedroom air of common household allergens like mold, dust mites, pet dander, and pollen.
  • Keep windows and doors closed to keep allergens out of your bedroom.
  • Sleep in a separate room from your pet to reduce exposure to pet hair and dander.
  • Take off your clothes when you come inside after being outdoors, especially during high pollen count days, and put them directly in the laundry.
  • Shower before bed to wash away any pollen or allergens that may be on your skin or hair.
  • Consult your doctor about taking allergy medication at night instead of the morning so that the dose is still strong in your system while you sleep.

Tonsillitis

Choking in your sleep can be a terrifying experience. It occurs when something obstructs your airway, causing you to wake up choking or gasping for air. This can be due to various reasons, one of the most common being Obstructive Sleep Apnoea (OSA). OSA is a sleep disorder characterised by brief interruptions in breathing due to a partial or complete blockage of the airway. This results in choking or gasping for air as the body responds to the lack of oxygen. Other causes of choking in sleep include acid reflux, post-nasal drip, and, in rare cases, tonsillitis.

Now, let's focus on tonsillitis:

The symptoms of tonsillitis include a sore throat, fever, swollen lymph nodes, and swollen tonsils. The tonsils may appear red and swollen, and you may observe white spots or a white, yellow, or grey coating on them. Swallowing may become painful, and you may also experience bad breath. In rare cases, tonsillitis can cause choking during sleep if the tonsils become so swollen that they block the airway.

The treatment for tonsillitis depends on whether the infection is viral or bacterial, and it usually takes about a week to recover. Good hygiene practices, such as frequent hand washing and avoiding sharing food and drinks, can help prevent the spread of tonsillitis. In some cases, surgery to remove the tonsils may be considered if tonsillitis occurs frequently or leads to serious complications.

If you experience choking in your sleep, it is important to seek medical advice to determine the underlying cause and receive appropriate treatment.

Alcohol and sedatives

Alcohol and certain medications are sedatives that can relax the muscles in the throat, increasing the risk of choking during sleep. While sedatives can be helpful for those who struggle to fall asleep, they should be used with caution and under the guidance of a healthcare provider. Sedatives can have a range of side effects, including drowsiness, dizziness, impaired coordination, and memory problems. In some cases, sedatives can also increase the risk of choking during sleep.

For many people, issues with falling asleep or staying asleep can result in an over-reliance on sleep medication. When used as prescribed, these medications can be helpful in the short term. However, when overused or combined with alcohol, serious side effects, physical dependence, or overdose may occur. Several studies have shown that the majority of patients entering treatment for alcohol misuse reported insomnia-related symptoms.

If you are suffering from both alcohol and sleeping pill addiction, you may need additional treatment. Integrating detox and treatment efforts for both substances can facilitate a safer, smoother recovery. In cases of recovery from co-occurring addiction to alcohol and sleeping pills, continued sedative-hypnotic treatment may not be a viable option. Instead, a more behavioral treatment-focused approach may be required.

Alcohol use and taking sedative hypnotics, such as sleep and anti-anxiety medications, can increase the risk of overdose. Like alcohol, these drugs suppress areas in the brain that control vital functions such as breathing. Ingesting alcohol and other drugs together intensifies their individual effects and could produce an overdose with even moderate amounts of alcohol. Alcohol at very high levels can hinder signals in the brain that control automatic responses, such as the gag reflex. With no gag reflex, a person who drinks to the point of passing out is in danger of choking on their vomit and dying from a lack of oxygen (asphyxiation).
