What is Sleep Apnea?

Sleep apnea is a serious sleep disorder characterized by repeated interruptions in breathing during sleep. These pauses in breathing, known as apneas, can last from a few seconds to over a minute and may occur dozens or even hundreds of times per night. As a result, the brain and the rest of the body may not get enough oxygen, leading to disturbed sleep and various health complications. There are three main types of sleep apnea: obstructive sleep apnea (OSA), central sleep apnea (CSA), and complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea.

Types of Sleep Apnea

  1. Obstructive Sleep Apnea (OSA):
    • Most common form of sleep apnea.
    • It occurs when the muscles in the back of the throat relax excessively during sleep, causing the airway to collapse or become blocked.
    • When the airway is blocked, breathing stops temporarily, which results in reduced oxygen levels. The brain then sends a signal to wake the person up briefly to reopen the airway, though this awakening is often so short that the individual may not remember it.
    • People with OSA may wake up feeling tired, experience poor-quality sleep, and snore loudly.
  2. Central Sleep Apnea (CSA):
    • Less common than OSA.
    • In CSA, the airway is not blocked, but the brain fails to send proper signals to the muscles that control breathing.
    • This type of sleep apnea is typically associated with issues in the brainstem, which controls breathing.
    • CSA can occur in individuals with certain medical conditions, such as heart failure or neurological diseases like Parkinson’s disease, or as a result of opioid use or high-altitude environments.
  3. Complex Sleep Apnea Syndrome (Treatment-emergent central sleep apnea):
    • A combination of both obstructive and central sleep apnea.
    • People with this condition have characteristics of OSA, but when treated (e.g., with continuous positive airway pressure therapy), they also develop central sleep apnea symptoms.

Causes of Sleep Apnea

The causes of sleep apnea vary depending on the type:

  • Obstructive Sleep Apnea is typically caused by the relaxation of throat muscles, which narrows the airway. Contributing factors include:
    • Excess weight: Fat deposits around the neck can obstruct the airway.
    • Anatomy: Physical traits such as a large neck, large tonsils, or a small airway can increase the likelihood of OSA.
    • Aging: Throat muscles may lose tone as a person ages.
    • Family history: A family history of OSA increases the risk.
    • Alcohol or sedative use: These substances relax the throat muscles.
    • Nasal congestion: Blocked nasal passages can make it harder to breathe.
  • Central Sleep Apnea occurs when the brain fails to signal the muscles to breathe properly. This can happen due to:
    • Heart conditions such as congestive heart failure.
    • Stroke or other neurological diseases.
    • Certain medications, including opioids.

Symptoms of Sleep Apnea

Common symptoms of sleep apnea include:

  • Loud snoring (particularly in OSA).
  • Episodes of breathing cessation during sleep, which may be witnessed by a bed partner.
  • Gasping for air during sleep.
  • Waking up with a dry mouth or sore throat.
  • Morning headaches.
  • Insomnia or difficulty staying asleep.
  • Excessive daytime sleepiness (hypersomnia), which leads to trouble staying awake, particularly during sedentary activities.
  • Difficulty concentrating or poor memory.
  • Mood changes, such as irritability, depression, or anxiety.
  • Night sweats.
  • Frequent need to urinate at night (nocturia).

Complications of Sleep Apnea

If left untreated, sleep apnea can lead to significant health risks:

  • Cardiovascular problems: The repeated drops in oxygen levels strain the cardiovascular system, increasing the risk of high blood pressure (hypertension), heart attacks, stroke, and irregular heartbeats (arrhythmias).
  • Type 2 diabetes: Sleep apnea is linked to insulin resistance, which can lead to type 2 diabetes.
  • Liver problems: People with sleep apnea are more likely to show signs of abnormal liver function, and liver scarring (nonalcoholic fatty liver disease) can occur.
  • Daytime fatigue: The repeated awakenings associated with sleep apnea impair restorative sleep, leading to severe daytime sleepiness and increased risk of accidents, especially in activities like driving or operating machinery.
  • Metabolic disorders: Sleep apnea is associated with metabolic syndrome, a cluster of conditions including high blood pressure, high cholesterol, high blood sugar, and excess fat around the waist.
  • Mental health issues: Sleep apnea can contribute to depression, anxiety, and cognitive decline due to the lack of restful sleep and oxygen deprivation.

Risk Factors for Sleep Apnea

Several factors increase the likelihood of developing sleep apnea:

  • Excess weight: Obesity significantly raises the risk of OSA due to fat deposits around the neck.
  • Age: Sleep apnea is more common in adults, particularly older individuals, as muscle tone diminishes with age.
  • Gender: Men are more likely to suffer from sleep apnea than women, though the risk for women increases after menopause.
  • Family history: A genetic predisposition can increase the risk of sleep apnea.
  • Neck circumference: A larger neck can mean narrower airways.
  • Smoking: Smoking increases inflammation and fluid retention in the upper airway, worsening sleep apnea.
  • Alcohol and sedatives: These substances relax the muscles in the throat, increasing the chances of airway collapse.

Diagnosis of Sleep Apnea

Diagnosis typically begins with an evaluation by a healthcare provider, who will inquire about symptoms and may refer the patient for a sleep study. There are two primary types of sleep studies:

  1. Polysomnography (PSG): This is an overnight sleep study conducted in a sleep lab where the patient’s brain waves, oxygen levels, heart rate, breathing patterns, and body movements are monitored.
  2. Home Sleep Apnea Test (HSAT): This is a simplified test that the patient can take home to monitor oxygen levels, airflow, and respiratory effort.

Treatment of Sleep Apnea

The treatment of sleep apnea depends on its severity and type. Common treatments include:

  1. Lifestyle changes:
    • Weight loss: Reducing excess weight can alleviate some symptoms of OSA.
    • Changing sleep positions: Sleeping on the side rather than the back can help reduce airway obstruction.
    • Avoiding alcohol and sedatives before bedtime to keep the airway muscles from relaxing too much.
  2. Continuous Positive Airway Pressure (CPAP):
    • CPAP is the most common and effective treatment for moderate to severe OSA.
    • The CPAP machine delivers a steady stream of air through a mask, keeping the airway open during sleep.
  3. Oral appliances:
    • For milder cases of OSA, a custom-fitted oral device can be used to reposition the jaw or tongue to keep the airway open.
  4. Surgery:
    • In some cases, surgery may be needed to remove tissue that blocks the airway, correct nasal or throat obstructions, or reposition structures within the throat.
    • Uvulopalatopharyngoplasty (UPPP): This procedure removes tissue from the back of the mouth and top of the throat.
    • Genioglossus advancement (GA): This procedure moves the tongue muscle attachment forward to keep the airway open.
    • Tracheostomy: In severe cases, this procedure creates an opening in the neck to allow breathing when other treatments have failed.
  5. Adaptive Servo-Ventilation (ASV):
    • For central sleep apnea, ASV is a device that learns the patient’s normal breathing pattern and adjusts air pressure to prevent pauses in breathing.

Managing Sleep Apnea

Effective management of sleep apnea requires a combination of treatment and lifestyle adjustments. Regular follow-up with healthcare providers ensures that treatments like CPAP or oral appliances are working effectively. Additionally, long-term lifestyle changes such as weight loss, quitting smoking, and managing other health conditions (e.g., hypertension) can significantly improve the condition.

Sleep apnea is a chronic condition that, if untreated, can lead to serious health issues. However, with proper diagnosis and treatment, individuals with sleep apnea can achieve better sleep quality, reduced symptoms, and improved overall health.
