What is Sleep Apnea?

Sleep apnea is a prevalent sleep disorder that occurs when a person experiences interruptions in their breathing while sleeping. It is characterized by pauses in breathing or shallow breaths, which can last from a few seconds to minutes and may occur multiple times throughout the night.

Sleep apnea manifests in three main forms: obstructive sleep apnea, central sleep apnea, and complex sleep apnea syndrome.

Obstructive sleep apnea: Occurs when the airway becomes partially or completely blocked during sleep, leading to pauses in breathing and disrupted sleep patterns. It is the most common form of sleep apnea.

Central sleep apnea: Is caused by a failure of the brain to transmit the proper signals to the muscles that control breathing. This results in periods of no breathing during sleep and can be associated with certain medical conditions.

Complex sleep apnea syndrome: Also known as treatment-emergent central sleep apnea, is a combination of obstructive and central sleep apnea. It typically starts as obstructive sleep apnea but then transitions to having central sleep apnea-like features after continuous positive airway pressure (CPAP) therapy is initiated.

Understanding the different types of sleep apnea is crucial for the proper diagnosis and treatment of this sleep disorder.


The symptoms of sleep apnea can often be subtle and are sometimes overlooked. They include:

  • Frequent loud snoring: This is a common symptom of sleep apnea and can often be a clue for diagnosis. Nonetheless, sleep apnea is not a condition that affects every individual who snores.
  • Repeated pauses in breathing during sleep: This may be observed by a partner or family member.
  • Excessive daytime sleepiness (hypersomnia): Individuals with sleep apnea often experience excessive drowsiness during the day, despite having seemingly adequate sleep.
  • Awakening with a dry mouth or sore throat: This can occur due to frequent openings of the mouth to breathe during sleep.
  • Morning headache: Lack of quality sleep can contribute to regular occurrences of morning headaches.
  • Difficulty staying asleep (insomnia): This could be due to repeated interruptions in breathing.
  • Attention problems: Impaired sleep quality can lead to difficulties in concentration and other cognitive functions.

Risk factors

Certain factors may increase the risk of developing sleep apnea, including:

  • Obesity: Being overweight or obese increases the likelihood of having sleep apnea due to excess soft tissue in the throat.
  • Age: Sleep apnea can occur at any age, but it is more common in adults over 40.
  • Sex: Men are more likely to have sleep apnea than women, although the risk increases in women after menopause.
  • Family history: If you have a family member with sleep apnea, you may be at an increased risk of developing it as well.
  • Smoking and alcohol use: Smoking and heavy alcohol consumption can increase the risk of developing sleep apnea due to their effects on the respiratory system.
  • Nasal congestion: Individuals with chronic nasal congestion may be more likely to have sleep apnea due to difficulties in breathing through the nose.

Who is affected by sleep apnea?

Sleep apnea affects a broad spectrum of people, cutting across various demographics. Here are some key points to consider:

  • Adults: Sleep apnea is more prevalent in adults, particularly those above 40 years of age. However, it can occur at any age.
  • Obese individuals: People who are overweight or obese are at a higher risk due to excess soft tissue in the throat that can interfere with breathing during sleep.
  • Men: Men are more likely to develop sleep apnea than women, though post-menopausal women also see a spike in cases.
  • Smokers and heavy drinkers: Lifestyle habits like smoking and heavy alcohol consumption may increase the risk due to their impact on the respiratory system.
  • Family history: Sleep apnea can have a genetic component. With higher incidence rates in individuals who have a family member with the condition.
  • People with chronic nasal congestion: Regular issues with nasal congestion may increase the likelihood of developing sleep apnea due to breathing difficulties.

Sleep apnea in children

While sleep apnea is more commonly associated with adults, it can also affect children. In fact, up to 5% of children may have sleep apnea.

Risk factors for pediatric include:

  • Obesity: Similar to adults, obesity can increase the risk of sleep apnea in children by causing excess tissue in the throat.
  • Enlarged tonsils and adenoids: Children with enlarged tonsils or adenoids have a higher risk of developing sleep apnea.
  • Family history: As with adults, having a family member with sleep apnea can increase the likelihood of a child developing it as well.
  • Neuromuscular disorders: Certain neuromuscular conditions like cerebral palsy or Down syndrome can increase the risk of sleep apnea in children.

These points highlight the variation in risk across different population groups. It’s crucial to understand that while these factors elevate the risk. Sleep apnea can affect anyone, highlighting the importance of awareness and regular check-ups for early detection and treatment.

Diagnosis of Sleep Apnea

If you suspect that you or a loved one may have sleep apnea, it is essential to consult a doctor for a proper diagnosis. The following tests may be used to diagnose sleep apnea:

  • Nocturnal polysomnography: This is an overnight test that records brain activity, eye movements, heart rate and rhythm, blood pressure, and oxygen levels while you sleep.
  • Home sleep apnea test: This is a simplified version of the polysomnography that can be conducted at home.
  • Oximetry: This test measures your blood oxygen levels using a small clip attached to your finger.

Medication and treatment

Treatment for sleep apnea depends on the severity and type of the disorder. Common treatments include:

  • Continuous Positive Airway Pressure (CPAP): This is a machine that delivers a constant flow of air through a mask worn over the nose or mouth to keep the airway open during sleep.
  • Oral appliances: These devices, when worn in the mouth, work to reposition the jaw and tongue, effectively maintaining an open airway.
  • Surgery: In some cases, surgery may be recommended to remove excess tissue from the back of the throat or correct a deviated septum.
  • Lifestyle changes: Losing weight, quitting smoking, and reducing alcohol consumption can help improve sleep apnea symptoms.

If left untreated, sleep apnea can lead to serious health problems such as high blood pressure, heart disease, and stroke. It is important to seek treatment if you suspect that you or a loved one may have sleep apnea to prevent potential complications. Overall, understanding the types of sleep apnea, its symptoms and risk factors allows for early detection and appropriate treatment. If you are experiencing symptoms of sleep apnea, consult a healthcare professional for proper diagnosis and treatment options. So, it is important to prioritize good sleep habits and seek help if necessary to maintain overall health and well-being.


In conclusion, sleep apnea is a common disorder that can have serious implications on one’s health if left untreated. It is essential to be aware of the various risk factors and symptoms associated with sleep apnea to seek timely diagnosis and treatment. With proper management and lifestyle changes, individuals can improve their quality of sleep and overall health. So, take care of your body and prioritize good sleep habits for a healthier, happier life.
