What Are The 3 Types Of Sleep Apnea?

Published on: December 16, 2024

Did you know that sleep apnea affects over 22 million Americans, with many cases remaining undiagnosed? This common yet serious condition interrupts breathing during sleep, often leading to daytime fatigue, poor concentration, and health problems like heart disease and diabetes. While most people have heard of sleep apnea, not everyone realizes that there are three distinct types of this disorder.

By understanding what the 3 types of sleep apnea are, we can help you identify symptoms and seek timely treatment.

What Is Sleep Apnea?

Sleep apnea is a sleep disorder usually characterized by repeated pauses in breathing during sleep. These pauses in breathing last from a few seconds to a minute and occur several times a night, disrupting normal sleep patterns.

Common symptoms include:

  • Loud snoring.
  • Gasping for air during sleep.
  • Daytime fatigue or sleepiness.
  • Difficulty concentrating.
  • Morning headaches.

Without treatment, sleep apnea can increase the chances of having heart disease, stroke, high blood pressure, and other health issues.

What Causes Sleep Apnea?

Sleep apnea occurs due to mechanical and structural issues in the airway, leading to interrupted breathing during sleep.

  • Relaxed Throat Muscles: When throat muscles and the tongue relax excessively during sleep, they can partially block the airway, making breathing difficult.
  • Soft Palate and Uvula: Relaxation of the soft palate and uvula can cause sagging, leading to airway obstruction, labored breathing, or even complete cessation of airflow.
  • Excess Tissue in Overweight Individuals: In people who are overweight, additional tissue in the airway can narrow it, restricting airflow.
  • Narrowed Airway: A restricted airway forces the body to work harder to breathe, though air may not flow effectively.
  • Central Sleep Apnea: This form occurs due to a temporary disconnect between the brain and breathing muscles, often linked to underlying brain or heart conditions.

3 Types Of Sleep Apnea

Sleep apnea comes in three main forms: Obstructive Sleep Apnea (OSA), Central Sleep Apnea (CSA), and Complex Sleep Apnea syndrome (CompSA). Each type affects breathing differently and requires tailored approaches for diagnosis and treatment.

  • Obstructive Sleep Apnea (OSA)

The most prevalent type of sleep apnea is called obstructive sleep apnea (OSA). It happens when the back of the throat muscles relax too much while you sleep, narrowing or blocking your airway. This obstruction interrupts airflow and can result in repeated episodes of shallow or paused breathing throughout the night.

Symptoms of OSA:

  • Loud, chronic snoring.
  • Gasping, choking, or pauses in breathing when you sleep.
  • Waking up with a completely dry mouth or sore throat.
  • Fatigue and excessive daytime sleepiness.

Causes of OSA:

  • Obesity increases fatty deposits around the airway.
  • Enlarged tonsils, adenoids, or other anatomical factors.
  • Aging, which naturally weakens throat muscles.
  • Family history of sleep apnea.

Treatment for OSA:

Treatment options include lifestyle changes like sleeping on your side, weight loss, and avoiding alcohol before bed. More advanced cases are often treated with continuous positive airway pressure (CPAP) therapy, which keeps the airway open by delivering constant air pressure. Alternatively, oral appliances that adjust the jaw and tongue position can effectively prevent airway blockage.

  • Central Sleep Apnea (CSA)

Central sleep apnea (CSA), which is less frequent than OSA, is caused by improper signals from the brain to the breathing muscles. Unlike OSA, there is no physical blockage; instead, the issue lies in the communication between the brain and the respiratory system.

Symptoms of CSA:

  • Pauses in breathing without snoring.
  • Difficulty staying asleep.
  • Shortness of breath upon waking.
  • Persistent daytime fatigue.

Causes of CSA:

  • Neurological conditions such as Parkinson's disease.
  • Heart problems like atrial fibrillation or heart failure.
  • Use of certain medications, particularly opioids.
  • High altitudes can disrupt normal breathing patterns.

Treatment for CSA:

Addressing the underlying health condition often alleviates CSA. In some cases, adaptive servo-ventilation (ASV) devices are used to monitor and adjust airflow, helping regulate breathing patterns during sleep. Severe cases may also require CPAP therapy or supplemental oxygen to maintain consistent airflow.

  • Complex Sleep Apnea Syndrome (CompSA)

Complex sleep apnea syndrome (CompSA), or treatment-emergent central sleep apnea, is a mix of obstructive sleep apnea and central sleep apnea. It develops when a patient with OSA begins CPAP therapy and subsequently experiences central sleep apnea symptoms.

Symptoms of CompSA:

  • A mix of symptoms from both OSA and CSA, such as snoring, choking, and pauses in breathing.
  • Persistent fatigue despite treatment with CPAP.
  • Sleep disturbances or trouble maintaining restful sleep.

Causes of CompSA:

  • Long-term untreated OSA.
  • Mismanagement or overuse of CPAP devices.
  • Underlying health conditions contribute to both OSA and CSA.

Treatment for CompSA:

Treatment for CompSA focuses on adjusting CPAP settings to balance airflow and reduce central apnea episodes. In more complex cases, switching to an ASV device can provide better regulation of breathing patterns. Monitoring and managing underlying health issues is also essential to ensure effective treatment.

Why Is Treating Sleep Apnea Important?

Sleep apnea isn't just about poor sleep; it has serious implications for overall health, including:

  • Increased risk of cardiovascular diseases.
  • Higher chances of developing diabetes.
  • Poor mental health due to fatigue and lack of focus.
  • Weakened immune system.

Early diagnosis and correct treatment can improve your health and quality of life.

FAQs

What is the Most Serious Sleep Apnea?

The most serious form of sleep apnea is severe obstructive sleep apnea (OSA), where the Apnea-Hypopnea Index (AHI) is greater than 30. This condition leads to frequent breathing interruptions and increases the risk of having heart disease, stroke, and other serious health complications.

How is Sleep Apnea Confirmed?

Sleep apnea is confirmed through nocturnal polysomnography, a sleep study where various bodily functions, like heart and brain activity, breathing patterns, and oxygen levels, are monitored while you sleep. Home sleep tests may also be used for simpler cases.

Who is at High Risk for Sleep Apnea?

Individuals with obesity, hormonal imbalances (such as low thyroid or high insulin), or a family history of sleep apnea are at higher risk. Genetic traits that affect airway structure, along with lifestyle variables like smoking, can also contribute to an increased risk.
