Severe sleep apnea is a dangerous sleep disorder resulting from difficulty breathing because of a stop-and-start breathing pattern during sleep. It may lead a patient to heart disease, stroke, or chronic fatigue if unmasking treatment is not recognized through symptoms such as loud snoring, gasping for air during sleep, and daytime fatigue. The upcoming article by CLM Sleep discusses the causes and symptoms of sleep apnea as well as some effective treatments to help people improve their sleep quality.
What is Severe Sleep Apnea?
Severe sleep apnea is considered the extreme form of obstructive sleep apnea (OSA), which describes a condition in which an individual’s airway becomes blocked repeatedly during sleep. In severe cases, the apnea-hypopnea index (AHI), which tallies the number of apneas (breathing pauses) and hypopneas (shallow breathing) observed per hour, typically exceeds 30, meaning that an affected person will have at least 30 stoppages in breathing per hour of sleep.
There are three severe types of sleep apnea, and they all have distinctly different causes and characteristics:
- Obstructive Sleep Apnea: By far the most common form of sleep apnea, OSA results from over-relaxation of muscles at the back of the throat, causing the airway to become partially or even fully obstructed. In a severe case, the patient’s airway may become blocked thirty or more times an hour, disrupting sleep and the body’s supply of oxygen.
- Central Sleep Apnea: Unlike obstructive sleep apnea, in central sleep apnea, the brain fails to transmit the signals to the muscles that are responsible for controlling breathing— as a result, no physical blockage, and yet the patient suffers from intermittent cessations in breathing. Less prevalent than OSA, this form can also prove itself to be quite severe.
- Complex Sleep Apnea: This is otherwise called treatment-emergent central sleep apnea. It combines both obstructive and central sleep apnea. It may look like an episode of obstructive sleep apnea, but it turns into a mixed form of apnea at the time of treatment, often with CPAP.
Symptoms of Severe Sleep Apnea
Your sleep partner may notice early signs of severe sleep apnea, such as loud snoring and episodes of breathing pauses during sleep. Both of you may observe symptoms like:
- Sudden awakenings with a feeling of choking,
- Decreased sex drive, mood changes,
- Night sweats.
You may also experience some daytime sleepiness, poor concentration, dry mouth, sore throat, and morning headache. If you detect and recognize these signs of severe sleep apnea early, it can be treated effectively.

Risk Factors
You develop a higher chance of suffering from severe sleep apnea if:
- Overweight or obese: The most important risk factor by far is the presence of obesity— more than 20% of affected individuals have OSA compared to something like 3% of people of average weight.
- Male gender: The man is between two to three times more likely than a premenopausal female to have sleep apnea. After menopause, the risks are about equal for males and females.
- Family history: The risk could be higher if one of your family members has sleep apnea too.
- Age: The risk increases with age, especially in your 60s and 70s.
- Smoking: Smokers are more likely to have sleep apnea.
- Coexisting health conditions: High blood pressure, diabetes, or asthma may raise the risk of developing sleep apnea.
- Chronic nasal congestion: People with chronic nasal congestion are twice as likely to have sleep apnea.
- Narrowed airways: Issues that narrow the airways, such as enlarged tonsils or adenoids, also contribute to an increased risk of sleep apnea.
Health Risks
According to the American Sleep Apnea Association (ASAA), undiagnosed and untreated sleep apnea can lead to several serious health impacts, including:
- Heart disease
- High blood pressure
- Stroke
- Depression
- Diabetes
Sleep apnea can also result in indirect consequences, such as an increased risk of traffic accidents due to drowsiness while driving.
Diagnosis of Severe Sleep Apnea
Diagnosis of severe sleep apnea requires a sleep study, during which you will be monitored while sleeping. This process can occur in a specialized facility (in-lab sleep study) or at home (home sleep study).
The doctor will also examine your throat, neck, and mouth, as well as ask about your medical history and sleep symptoms. If you have severe sleep apnea, you may need a blood test to rule out other conditions, such as hypothyroidism.

Severe Sleep Apnea Treatment
Sleep apnea can cause many health complications if left untreated. However, several effective treatment methods are available, tailored to each patient’s needs and severity of the condition. For severe sleep apnea, here are some common treatment options.
Lifestyle changes
A number of measures will be recommended to individuals with severe sleep apnea to improve their health:
- Keeping a healthy weight is important
- Smoking should be stopped
- Regular exercise is essential
- Consume less alcohol
Continuous Positive Airway Pressure (CPAP)
One of the most common treatments for severe sleep apnea is a CPAP machine. This device provides a continuous airflow through a mask, helping to keep the airway open throughout sleep. CPAP machines effectively reduce the frequency of apneas and improve sleep quality. However, adjustments may be needed to find each user’s best mask type and pressure settings.
Bi-level Positive Airway Pressure (BiPAP)
Bi-level Positive Airway Pressure (BiPAP) is a non-invasive ventilation therapy commonly used to treat severe obstructive sleep apnea (OSA). BiPAP is particularly useful for patients who do not find comfort with CPAP machines.
The BiPAP machine delivers two levels of air pressure:
- Higher Inhalation Pressure (IPAP): This assists inhalation and keeps the airway open.
- Lower Exhalation Pressure (EPAP): This makes exhalation easier.
Surgery
Doctors may recommend several surgical options, including:
- Uvulopalatopharyngoplasty (UPPP) to remove excess tissue and create space for the airway.
- Upper airway stimulation to improve airflow.
- Jaw surgery to create additional space for the airway.
- Tracheostomy is typically performed in severe, life-threatening cases of obstructive sleep apnea.
- Implantation of devices to reduce upper airway collapse.
Oral appliances
Dental devices are designed to reposition the jaw and tongue, helping to keep the airway clear. These devices are very useful for individuals with mild to moderate obstructive sleep apnea and may also benefit some severe sleep apnea cases. They are often considered more comfortable than CPAP machines and are easier to travel with and use. However, to ensure effectiveness, it’s important to consult a dentist or orthodontist specializing in sleep apnea.
Prevention
You must make lifestyle changes and adopt proactive measures to prevent severe sleep apnea. Here are some effective strategies:
- Maintain a Healthy Weight: Obesity is a major risk factor for severe sleep apnea. Losing weight can help improve or eliminate symptoms for many individuals.
- Exercise Regularly: Regular physical activity helps maintain a healthy weight and enhances overall health. Aim for at least 150 minutes of moderate exercise each week.
- Avoid Alcohol and Sedatives: Alcohol and sedatives can relax the muscles in the throat, worsening sleep apnea. It’s best to avoid these substances, especially before bedtime.
- Quit Smoking: Smoking increases inflammation and fluid retention in the upper airway, leading to sleep apnea. Quitting smoking not only improves overall health but also reduces the severity of symptoms.
- Sleep on Your Side: Sleeping on your back can exacerbate sleep apnea. Try to sleep on your side to keep the airway open.
- Establish a Regular Sleep Routine: Going to bed and waking up simultaneously daily will improve sleep quality and regulate your body’s internal clock.
- Avoid Heavy Meals Before Bed: Eating large meals close to bedtime can increase the likelihood of sleep apnea. Aim to have dinner at least two to three hours before sleeping.
- Stay Hydrated: Dehydration can thicken mucus in the throat, leading to airway obstruction. Ensure you drink enough water throughout the day.
- Manage Allergies and Nasal Congestion: Allergies and nasal congestion can worsen sleep apnea. Use decongestants or antihistamines as needed and keep your sleeping environment allergen-free.
- Regular Medical Checkups: Regular visits to your healthcare provider help monitor your health and catch any potential issues early, allowing for timely intervention.
