What Is Sleep Apnea?

Sleep apnea is a common but serious disorder where your breathing repeatedly stops and starts while you sleep. These pauses can last for seconds or even minutes and often happen dozens of times per night — without you even realizing it.

The impact is more than restless nights. Untreated sleep apnea can lead to chronic fatigue, weight gain, high blood pressure, heart disease, stroke, and mental health struggles such as depression or anxiety. If you suspect you might have it, getting a proper diagnosis is not just important, it is essential for protecting your health and quality of life.

Types & Causes of Sleep Apnea

Speak with a Sleep Physician

  • Obstructive Sleep Apnea (OSA)

    The most common type, OSA occurs when throat muscles relax and cause a physical blockage of the airway. Risk factors include:

    • Being overweight or obese
    • Neck circumference over 17 inches (men) or 16 inches (women)
    • Chronic medical conditions including but not limited to high blood pressure, diabetes, kidney disease, lung disease including asthma/COPD, and heart disease
    • Age, alcohol or sedative use, smoking, and family history
    • Importantly, menopausal women may not have any of the above risk factors and still have sleep apnea

  • Central Sleep Apnea (CSA)

    Less common, CSA happens when the brain fails to signal the muscles to breathe, often related to other medical conditions such as heart failure or neurological issues.

    Sleep apnea may also be linked to:

    • Diabetes
    • Hypertension
    • Depression, anxiety, and PTSD
    • Medication use and chronic conditions

Common Symptoms of Sleep Apnea

If you’re researching your symptoms, these may sound familiar:

  • Loud or frequent snoring
  • Gasping or choking during sleep
  • Excessive daytime sleepiness or difficulty staying awake
  • Morning headaches
  • Difficulty concentrating or memory issues
  • Mood changes, irritability, or depression
  • Restless sleep or frequent awakenings
  • Dry mouth or sore throat in the morning
  • Chest pain at night
  • Frequent night time bathroom breaks
  • Importantly, menopausal women may not have any of the above risk factors and still have sleep apnea

You don’t need to have all of these symptoms — even one or two may indicate an underlying sleep disorder.

How Is Sleep Apnea Diagnosed?

At The Sleep Institute, all assessments are managed by board-certified Sleep Physicians, not technicians.

We use a combination of:

  • Sleep questionnaires and screening tools
  • Sleep diaries
  • Level 3 home sleep testing using medical-grade portable devices
  • Level 1 and Level 2 sleep studies for more complex cases

Your care is guided by a physician who can accurately diagnose and recommend appropriate treatment, not just sell you a CPAP machine.

Risks of Untreated Sleep Apnea

Sleep apnea is not just a sleep problem — it’s a serious medical issue. If left untreated, it can:

  • Make it harder to lose weight or manage blood pressure
  • Reduce the effectiveness of antidepressants and anxiety medications
  • Increase your risk of heart disease, stroke, and diabetes
  • Lead to motor vehicle accidents and work-related injuries
  • Cause long-term disability, absenteeism, and reduced productivity
  • Cause Impaired cognition (foggy brain), low energy, and low mood
