What Is Sleep Apnea?
Sleep apnea happens when breathing stops and starts repeatedly during sleep. The word "apnea" means "without breath." This condition affects millions of people worldwide, including many in Singapore.
During normal sleep, muscles relax naturally. However, in people with sleep apnea, throat muscles relax too much. This causes the airway to narrow or close completely. As a result, breathing stops for several seconds.
When breathing stops, oxygen levels drop in the blood. The brain notices this and wakes the person briefly to restart breathing. This process repeats many times throughout the night. Most people don't remember these brief awakenings.
Types of Sleep Apnea
There are three main types of sleep apnea:
Obstructive Sleep Apnea (OSA) is the most common type. It occurs when throat muscles relax and block the airway during sleep.
Central Sleep Apnea happens when the brain doesn't send proper signals to breathing muscles. This type is less common than OSA.
Complex Sleep Apnea combines both obstructive and central types. Some people develop this after starting CPAP treatment.
How Common Is Sleep Apnea?
Research studies show sleep apnea affects many people. However, exact numbers vary between different populations and study methods.
Some studies suggest millions of people have undiagnosed sleep apnea. Many don't realize they have this condition because symptoms occur during sleep.
Sleep apnea can affect anyone at any age. However, certain factors increase the risk of developing this condition.
Sleep Apnea in Children
Children can also have sleep apnea, though it often looks different from adult cases.
Signs in Babies and Toddlers
- Noisy breathing during sleep
- Frequent waking at night
- Difficulty feeding or poor weight gain
- Sleeping in unusual positions
- Excessive sweating during sleep
Signs in School-Age Children
- Loud snoring most nights
- Pauses in breathing during sleep
- Restless or fragmented sleep
- Morning headaches
- Difficulty paying attention in school
- Hyperactive behavior during the day
- Bedwetting in older children
Common Causes in Children
Large tonsils and adenoids are the most common cause of childhood sleep apnea. These tissues can block the airway when they become enlarged.
Other causes include:
- Obesity
- Certain genetic conditions
- Muscle weakness
- Jaw or facial structure differences
Why Treatment Matters for Children
Untreated sleep apnea can affect a child's growth and development. It may impact:
- Academic performance
- Behavior and attention
- Physical growth
- Heart health
- Overall quality of life
Sleep Apnea in Adults
Adult sleep apnea often develops gradually. Many people have symptoms for years before getting diagnosed.
Complete Signs and Symptoms of Sleep Apnea
Understanding sleep apnea symptoms helps identify this condition early. Symptoms can vary between individuals and may develop gradually over time.
Nighttime Sleep Apnea Symptoms
Loud Snoring: This is often the first sign family members notice. However, not everyone who snores has sleep apnea.
Breathing Pauses: Partners may observe moments when breathing stops completely during sleep, followed by gasping or choking sounds.
Restless Sleep: Frequent tossing and turning, even when getting adequate sleep hours.
Night Sweats: Excessive sweating during sleep without obvious environmental causes.
Frequent Urination: Waking multiple times to use the bathroom, especially in older adults.
Dry Mouth: Waking with an extremely dry mouth or sore throat.
Daytime Sleep Apnea Symptoms
Excessive Sleepiness: Feeling tired despite spending adequate time in bed. This affects daily activities and work performance.
Morning Headaches: Regular headaches upon waking that improve throughout the day.
Difficulty Concentrating: Problems with focus, memory, and decision-making at work or school.
Mood Changes: Increased irritability, anxiety, or depression symptoms that seem unexplained.
High Blood Pressure: Many people with sleep apnea develop elevated blood pressure.
Physical Signs of Sleep Apnea
Neck Size: A neck circumference over 17 inches in men or 16 inches in women increases risk.
Weight Distribution: Excess weight around the neck and upper body area.
Facial Structure: Small jaw, large tongue, or enlarged tonsils can contribute to airway obstruction.
Nasal Problems: Chronic congestion or structural issues that affect breathing.
Risk Factors for Adults
Several factors increase the likelihood of developing sleep apnea:
Age: Risk increases with age, particularly after 40 years old.
Weight: Excess weight, especially around the neck area, can narrow the airway.
Gender: Men are more likely to develop sleep apnea than women. However, women's risk increases after menopause.
Family History: Sleep apnea sometimes runs in families.
Smoking: Smoking increases inflammation and fluid retention in the airway.
Alcohol Use: Alcohol relaxes throat muscles, which can worsen sleep apnea.
Nasal Congestion: Chronic nasal problems can make breathing during sleep more difficult.
Health Effects of Untreated Sleep Apnea
Sleep apnea affects the entire body, not just sleep quality. The repeated drops in oxygen levels and fragmented sleep can lead to various health problems.
Short-Term Effects
- Daytime fatigue and sleepiness
- Difficulty concentrating
- Memory problems
- Mood changes
- Morning headaches
- Dry mouth upon waking
Long-Term Health Risks
Research links untreated sleep apnea to several serious health conditions:
Heart Problems: Sleep apnea may increase the risk of high blood pressure, heart attack, and stroke.
Diabetes: The condition may affect how the body processes sugar, potentially increasing diabetes risk.
Weight Gain: Poor sleep can affect hormones that control hunger and fullness.
Depression: Sleep disruption may contribute to mood disorders.
Weakened Immune System: Poor sleep quality can affect the body's ability to fight infections.
Getting Diagnosed
Proper diagnosis requires professional medical evaluation. Healthcare providers use several methods to diagnose sleep apnea.
Medical History and Physical Exam
Doctors will ask about symptoms, sleep habits, and medical history. They may examine the throat, neck, and nasal passages.
Sleep Studies
Sleep studies monitor breathing, heart rate, and other body functions during sleep. There are two main types:
In-Lab Sleep Study: This comprehensive test takes place in a sleep center overnight. Technicians monitor multiple body functions while you sleep.
Home Sleep Test: This simplified test allows monitoring at home using portable equipment. It measures breathing, oxygen levels, and effort to breathe.

Jaw Exercises: Open mouth wide, move jaw left and right. Hold each position for 10 seconds.
Types of Sleep Apnea and Their Characteristics
Understanding different types helps identify the most appropriate treatment approach.
Obstructive Sleep Apnea (OSA)
This is the most common type, affecting about 90% of people with sleep apnea.
Causes: Throat muscles relax excessively, causing airway tissues to collapse and block breathing.
Risk Factors: Obesity, large neck circumference, male gender, older age, family history.
Symptoms: Loud snoring, breathing pauses, daytime sleepiness, morning headaches.
Treatment Options: CPAP therapy, weight loss, positional therapy, oral appliances, surgery.
Central Sleep Apnea (CSA)
Less common but potentially more serious, affecting the brain's control of breathing.
Causes: Brain fails to send proper signals to breathing muscles during sleep.
Risk Factors: Heart failure, stroke, high altitude, certain medications.
Symptoms: Less snoring than OSA, but similar daytime fatigue and concentration problems.
Treatment Options: Treating underlying conditions, adaptive servo-ventilation, medication.
Mixed or Complex Sleep Apnea
Combination of both obstructive and central types.
Development: Often emerges when OSA patients begin CPAP therapy and develop central episodes.
Treatment Challenges: Requires specialized equipment and careful monitoring.
Management: BiPAP or adaptive servo-ventilation devices, medication adjustments.
Healthy Sleep Habits for Better Rest
Good sleep hygiene forms the foundation of sleep apnea management and overall health.
Creating the Ideal Sleep Environment
Temperature Control: Keep bedroom between 65-70°F (18-21°C) for optimal sleep.

Regular Exercise: Physical activity supports weight control and improves cardiovascular health.
Stress Management: Chronic stress can worsen sleep quality and overall health.
Social Support: Family understanding and support improve treatment adherence and outcomes.
CPAP Therapy
Continuous Positive Airway Pressure (CPAP) is a common treatment for moderate to severe sleep apnea.
CPAP machines deliver steady air pressure through a mask worn during sleep. This air pressure keeps the airway open, preventing breathing interruptions.
Modern CPAP machines are quieter and more comfortable than older models. They often include features like:
- Heated humidifiers to reduce dryness
- Ramp settings that gradually increase pressure
- Data tracking to monitor usage
Proper mask fitting is crucial for CPAP success. Different mask styles work better for different people. For detailed information about CPAP options, the CPAP machines guide provides comprehensive educational content about available technologies.
Other Treatment Options
Oral Appliances: Custom-made dental devices can help keep the airway open by repositioning the jaw or tongue.
Surgery: Various surgical procedures can remove or reduce tissue that blocks the airway. Surgery is typically considered when other treatments haven't worked.
BiPAP Therapy: Bilevel Positive Airway Pressure provides two different pressure levels - higher when breathing in, lower when breathing out.
Inspire Therapy: This newer treatment uses a small implanted device to stimulate nerves that control airway muscles.
Living with Sleep Apnea Treatment
Successful sleep apnea treatment often requires lifestyle adjustments and ongoing commitment.
CPAP Success Tips
- Use the machine every night, even for naps
- Keep equipment clean and well-maintained
