Sleep Apnea Simplified

Written By VIKTORIA SCHULER

What Is Sleep Apnea Anyway?

Sleep apnea is a common disorder characterized by pauses in breathing or shallow breaths during sleep. These breathing interruptions can last from a few seconds to minutes and may occur 30 times or more per hour. There are three main types:

Obstructive Sleep Apnea (OSA)

What happens: The most common form, where throat muscles relax and block the airway during sleep.

The mechanics: Think of your airway as a straw. When you're awake, muscles keep it open. During sleep, these muscles relax, and in some people, this causes partial or complete blockage – like pinching that straw closed.

Central Sleep Apnea (CSA)

What happens: The brain fails to send proper signals to the breathing muscles.

The mechanics: Unlike OSA, the airway remains open, but the brain doesn't consistently trigger breathing – like forgetting to sip through an open straw.

Complex/Mixed Sleep Apnea

What happens: A combination of both obstructive and central sleep apnea.

Did You Know? While snoring is a common symptom of sleep apnea, not all snorers have sleep apnea, and not everyone with sleep apnea snores loudly. Some people with severe sleep apnea, particularly women and those with a normal BMI, may not snore significantly.

Why Should You Care About Sleep Apnea?

Beyond just feeling tired, untreated sleep apnea is associated with serious health consequences:

Cardiovascular Impact

  • Increased risk of high blood pressure

  • Higher chances of heart attack and stroke

  • Irregular heartbeats (arrhythmias)

  • Heart failure exacerbation

Metabolic Effects

  • Poor blood sugar control in diabetics

  • Insulin resistance

  • Weight gain and difficulty losing weight

  • Liver problems

Neurological Consequences

  • Morning headaches

  • Cognitive impairment and brain fog

  • Increased risk of accidents

  • Mood disorders including depression and anxiety

The Sneaky Symptoms: How to Recognize Sleep Apnea

Nighttime Signs

  • Loud, persistent snoring

  • Witnessed breathing pauses

  • Gasping or choking during sleep

  • Restless sleep

  • Night sweats

  • Frequent bathroom trips

  • Teeth grinding (bruxism)

Daytime Symptoms

  • Excessive daytime sleepiness

  • Morning headaches

  • Difficulty concentrating

  • Irritability or mood changes

  • Dry mouth or sore throat upon waking

  • Decreased libido

  • Falling asleep during routine activities

Risk Factors: Are You More Likely to Have Sleep Apnea?

Physical Characteristics

  • Excess weight (BMI >25)

  • Large neck circumference (>17 inches for men, >16 inches for women)

  • Nasal obstruction or congestion

  • Enlarged tonsils or adenoids (especially in children)

  • Recessed chin or large overbite

  • Family history of sleep apnea

Lifestyle Factors

  • Alcohol consumption (especially before bedtime)

  • Sedative use

  • Smoking

  • Irregular sleep schedule

Medical Conditions

  • Hypothyroidism

  • Acromegaly

  • Down syndrome

  • Neuromuscular disorders

  • Chronic nasal congestion

Risk reality check: While obesity is a significant risk factor, approximately 20-30% of people with sleep apnea are at a normal weight. Facial structure, age, and hormonal factors play important roles too.

Getting Diagnosed: The Sleep Study Decoded

Types of Sleep Studies

  • Polysomnography (PSG): The gold standard, conducted in a sleep lab

  • Home sleep apnea test (HSAT): More convenient but less comprehensive

  • Split-night study: Combines diagnostic testing and CPAP titration

  • Multiple sleep latency test (MSLT): Helps distinguish sleep apnea from narcolepsy

What They Measure

  • Airflow: Through nose and mouth

  • Respiratory effort: Chest and abdominal movement

  • Blood oxygen levels: How much oxygen saturation drops

  • Heart rate and rhythm: How the heart responds to apneas

  • Brain waves: Sleep stages and arousals

  • Limb movements: Detect restless leg syndrome

  • Body position: How sleeping position affects breathing

The AHI: Your Sleep Apnea "Score"

The Apnea-Hypopnea Index (AHI) measures sleep apnea severity:

  • Mild: 5-15 events per hour

  • Moderate: 15-30 events per hour

  • Severe: More than 30 events per hour

But there's more to the story: Some patients with "mild" AHI scores can have severe symptoms if their oxygen levels drop significantly during events. Others with "severe" scores may have minimal symptoms. Treatment decisions should consider both the number and impact of breathing events.

Treatment Options: Beyond Just CPAP

Positive Airway Pressure Therapies

  • CPAP (Continuous Positive Airway Pressure): The most common treatment, delivers constant air pressure

  • BiPAP (Bi-level Positive Airway Pressure): Provides higher pressure during inhalation and lower during exhalation

  • APAP (Automatic Positive Airway Pressure): Automatically adjusts pressure throughout the night

  • ASV (Adaptive Servo-Ventilation): For complex sleep apnea and certain heart conditions

Oral Appliances

  • Custom-fitted devices that reposition the jaw and tongue

  • Best for mild to moderate OSA, especially for those who can't tolerate CPAP

  • Requires fitting and adjustment by a dentist specializing in sleep medicine

Positional Therapy

  • Devices that prevent back-sleeping

  • Helpful for those whose apnea occurs primarily in certain sleep positions

  • Options range from simple tennis ball techniques to sophisticated vibrating devices

Surgical Options

  • Uvulopalatopharyngoplasty (UPPP): Removes excess tissue in the throat

  • Maxillomandibular advancement: Moves the jaw forward

  • Hypoglossal nerve stimulation: Implanted device that stimulates the tongue to maintain muscle tone during sleep

  • Weight loss surgery: Can dramatically improve OSA in appropriate candidates

Lifestyle Changes

  • Weight loss (even 10% can significantly improve symptoms)

  • Alcohol reduction, especially before bedtime

  • Regular exercise

  • Establishing consistent sleep schedules

  • Treatment of nasal congestion

CPAP Success: Making Friends with Your Machine

For those prescribed CPAP, these tips can help improve adherence:

Mask Matters

  • Try different styles (nasal pillows, nasal mask, full face)

  • Ensure proper fit – not too tight, not too loose

  • Consider mask liners for sensitive skin

  • Clean regularly according to manufacturer instructions

Comfort Enhancements

  • Use the ramp feature to gradually increase pressure

  • Try the heated humidifier to prevent dryness

  • Experiment with different tubing options (standard, heated, flexible)

  • Consider a CPAP pillow designed to accommodate masks

Psychological Adaptation

  • Practice wearing the mask while awake for short periods

  • Use relaxation techniques when putting on the mask

  • Focus on the benefits you notice rather than the inconvenience

  • Join a support group for tips and encouragement

Special Populations and Sleep Apnea

Women and Sleep Apnea

  • Often present with different symptoms (insomnia, fatigue without obvious daytime sleepiness)

  • May be misdiagnosed with depression, anxiety, or insomnia

  • Hormonal changes affect risk (menopause increases risk significantly)

Children and Sleep Apnea

  • Often related to enlarged tonsils and adenoids

  • Symptoms may include bedwetting, night terrors, ADHD-like behavior

  • Can affect growth and development

  • Frequently resolves after tonsillectomy and adenoidectomy

Elderly and Sleep Apnea

  • Higher prevalence but often overlooked as "normal aging"

  • May contribute to cognitive decline

  • Can complicate management of other health conditions

  • May present differently than in younger adults

The Connection to Other Conditions

Sleep apnea has significant relationships with:

Cardiovascular Disease

  • Treating sleep apnea can help control blood pressure

  • May reduce risk of heart failure progression

  • Improves outcomes after cardiac events

Diabetes

  • Sleep apnea treatment may improve insulin sensitivity

  • Better sleep can help with weight management

  • Reduces inflammation that affects glucose control

Respiratory Conditions

  • Can worsen COPD (overlap syndrome)

  • Increases risk of respiratory failures

  • May complicate asthma management

Traveling with Sleep Apnea

Tips for taking your therapy on the road:

  • Consider a travel-specific CPAP device

  • Bring a copy of your prescription

  • Research power adapter needs for international travel

  • Carry your CPAP as a medical device (doesn't count toward carry-on limits)

  • Use distilled water or CPAP wipes instead of the humidifier for short trips

Beyond the Machine: Complementary Approaches

While not replacements for primary treatment, these approaches can support sleep apnea management:

  • Myofunctional therapy: Exercises to strengthen tongue and throat muscles

  • Didgeridoo playing: Research shows it may strengthen airway muscles

  • Singing exercises: Similar benefits to didgeridoo but potentially more accessible

  • Yoga and breathing practices: Improve respiratory strength and control

  • Anti-inflammatory diet: May reduce airway inflammation
