Introduction

Sleep apnea is a sleep disorder characterized by repeated interruptions in breathing during sleep. These pauses in breathing can last for seconds to minutes and can occur multiple times throughout the night, leading to disrupted sleep and low oxygen levels. The most common type is obstructive sleep apnea (OSA), where the throat muscles relax excessively, blocking the airway. Central sleep apnea occurs when the brain fails to signal the muscles to breathe. Sleep apnea can lead to various health problems, including daytime fatigue, cardiovascular issues, and high blood pressure.

Normal sleep cycles

Causes

  • Obstructive Sleep Apnea (OSA):

    • Excess Weight: Obesity increases the likelihood of airway obstruction.
    • Anatomical Factors: Enlarged tonsils, a thick neck, or a narrow airway.
    • Aging: Muscle tone decreases with age, increasing the risk.
    • Gender: Men are more likely to develop OSA, though women are also at risk.
    • Family History: Genetics can play a role.
    • Smoking: Contributes to airway inflammation and obstruction.
    • Alcohol and Sedatives: Relax throat muscles, leading to airway collapse.

  • Central Sleep Apnea:

    • Heart Failure: Associated with central sleep apnea.
    • Stroke: Can affect brain regions that control breathing.
    • Certain Medical Conditions: Such as neurological disorders.

  • Complex Sleep Apnea Syndrome:

    • Combination of obstructive and central sleep apnea, often seen in individuals who have both types.

Symptoms

  • Loud snoring
  • Pauses in breathing during sleep
  • Excessive daytime sleepiness
  • Fatigue or feeling unrefreshed after sleep
  • Morning headaches
  • Difficulty concentrating
  • Irritability or mood changes
  • Dry mouth or sore throat upon waking
  • Frequent nighttime awakenings to urinate

Stages of The Apnea

  1. Mild Sleep Apnea

    • Apnea events occur 5-15 times per hour of sleep.
    • Symptoms may be less noticeable but can include mild daytime sleepiness.

  2. Moderate Sleep Apnea

    • Apnea events occur 15-30 times per hour of sleep.
    • Symptoms are more pronounced, with increased daytime sleepiness and potential impacts on overall health.

  3. Severe Sleep Apnea

    • Apnea events occur more than 30 times per hour of sleep.
    • Significant symptoms such as severe daytime sleepiness, frequent nighttime awakenings, and increased risk of cardiovascular problems.

Treatment

  1. Lifestyle Changes:

    • Weight Loss: Reducing excess weight can decrease symptoms.
    • Positional Therapy: Sleeping on your side instead of your back.
    • Avoiding Alcohol and Sedatives: These can relax throat muscles and worsen symptoms.

  2. Continuous Positive Airway Pressure (CPAP):

    • A machine that uses a hose connected to a CPAP mask to keep the airway open during sleep.

  3. Positive Airway Pressure Therapy:

    • BiPAP: Provides two levels of pressure (inhalation and exhalation) for more comfort.

  4. Oral Appliances:

    • Dental devices that reposition the lower jaw and tongue to keep the airway open.

  5. Surgery:

    • Uvulopalatopharyngoplasty (UPPP): Removal of excess tissue from the throat.
    • Genioglossus Advancement (GA): Repositioning the tongue muscle attachment.
    • Inspire Therapy: A surgically implanted device that stimulates the airway muscles to prevent collapse.

  6. Treatment of Underlying Conditions:

    • Managing conditions like heart failure or neurological disorders that contribute to central sleep apnea.

What Should You Avoid

  • Smoking
  • Excessive alcohol consumption
  • Sedatives or tranquilizers
  • Overweight and obesity
  • Sleeping on your back (if advised by a doctor)
  • Heavy meals close to bedtime
