Sleep Apnea: A Deeper Dive into Its Types and When to be Concerned.

‍Sleep apnea is a sleep disorder that’s more common than you might think. It’s characterized by the cessation of breathing during sleep, leading to numerous health risks if left untreated. This article aims to shed light on the different types of sleep apnea and the potential warning signs to watch out for.

Understanding Sleep Apnea

Sleep apnea, as a term, originates from the Greek word “apnea” meaning “without breath”. It is a sleep-related breathing disorder that causes repeated interruptions in breathing during sleep. It affects both adults and children and is categorized into three types: Obstructive Sleep Apnea (OSA), Central Sleep Apnea (CSA), and mixed or complex sleep apnea, which is a combination of both OSA and CSA.

Obstructive Sleep Apnea (OSA)

OSA, the most common form of sleep apnea, occurs when the muscles in the back of the throat relax excessively during sleep. This relaxation causes the airway to narrow or close as you breathe in, leading to a decrease in blood oxygen levels. The brain then signals you to wake up to reopen your airway – an event that often occurs so briefly that you don’t remember it.

Central Sleep Apnea (CSA)

Contrary to OSA, CSA is not caused by a physical blockage of the airway but by a failure of the brain to signal the muscles to breathe. This occurs due to instability in the respiratory control center. CSA is less common than OSA and is often associated with serious illnesses, especially those affecting the heart and brain.

Recognizing Symptoms of Sleep Apnea

Recognizing the symptoms of sleep apnea is the first step towards diagnosis and treatment. Both OSA and CSA share similar symptoms making it difficult to distinguish between the two without professional help. Some common signs include:

  1. Loud snoring: This is often more prominent in OSA. However, not everyone who snores has sleep apnea.
  2. Breathing cessation during sleep: This is often reported by another person witnessing the individual sleep.
  3. Abrupt awakenings followed by gasping or choking: These are the body’s response to lack of oxygen.
  4. Excessive daytime sleepiness: Sleep apnea can cause frequent awakenings at night leading to insufficient sleep.
  5. Dry mouth or sore throat upon waking up: This is due to breathing through the mouth during sleep.
  6. Headaches in the morning: These can be caused by low oxygen or high carbon dioxide levels during sleep.
  7. Difficulty concentrating during the day: This is attributed to insufficient sleep.
  8. Mood swings: Sleep deprivation can lead to irritability and mood changes.

Diagnosing Sleep Apnea

Diagnosing sleep apnea usually involves an overnight monitoring at a sleep center to record breathing patterns, heart rate, brain activity, and blood oxygen levels while sleeping. This test, known as polysomnography, can help determine whether you have sleep apnea and how severe it is.

For some cases of suspected OSA, home sleep tests may be an option. They involve measuring heart rate, blood oxygen level, airflow, and breathing patterns. However, they don’t monitor sleep stages, making it less accurate than polysomnography.

Living with Sleep Apnea

Living with sleep apnea can be challenging, but with the right sleep apnea treatment plan, the condition can be effectively managed. It’s crucial to follow the treatment plan, maintain a healthy weight, quit smoking, and limit alcohol intake. Sleep position can also affect sleep apnea severity. It’s typically recommended to avoid sleeping on the back as this can cause the tongue and soft tissues to obstruct the airway.

When to Worry

Sleep apnea is a serious sleep disorder that needs medical attention. If left untreated, it can lead to various health problems, including high blood pressure, stroke, heart failure, irregular heartbeats, and diabetes. It can also worsen ADHD and contribute to poor performance in everyday activities. If you or a loved one has symptoms suggestive of sleep apnea, such as loud snoring, long pauses in breathing, gasping or choking during sleep, and excessive daytime sleepiness, it’s time to consult a healthcare professional.


Sleep apnea is not merely a nuisance; it’s a serious sleep disorder that requires attention. Understanding the different types of sleep apnea, recognizing the symptoms, and seeking timely medical intervention can significantly reduce health risks and improve the quality of life for those affected. Remember, sleep is not a luxury; it’s a necessity. Don’t let sleep apnea rob you of this vital health component.
