Sleep apnea is a serious sleep disorder characterized by repeated interruptions in breathing during sleep. These interruptions, or apneas, can last for seconds to minutes and may occur hundreds of times a night, leading to fragmented sleep and reduced oxygen levels in the blood. This condition can result in excessive daytime drowsiness, difficulty concentrating, and an increased risk of cardiovascular problems. Understanding the signs and symptoms of sleep apnea is crucial for timely diagnosis and treatment. Addressing sleep apnea effectively can significantly improve quality of life and prevent potential health complications associated with untreated sleep disruptions.

Sleep apnea is a sleep disorder where breathing repeatedly stops and starts during sleep. This occurs due to a blockage in the airway (obstructive sleep apnea) or a failure in the brain’s signals to the muscles that control breathing (central sleep apnea). These interruptions can last from a few seconds to minutes and often result in loud snoring or choking sounds. Sleep apnea leads to poor sleep quality and can cause excessive daytime fatigue, making it important to recognize and treat this condition to improve overall health and well-being.
There are three common types of sleep apnea:
Obstructive Sleep Apnea (OSA)
Sleep apnea is a sleep disorder where breathing repeatedly stops and starts during sleep. This occurs due to a blockage in the airway (obstructive sleep apnea) or a failure in the brain’s signals to the muscles that control breathing (central sleep apnea). These interruptions can last from a few seconds to minutes and often result in loud snoring or choking sounds. Sleep apnea leads to poor sleep quality and can cause excessive daytime fatigue, making it important to recognize and treat this condition to improve overall health and well-being.
Central Sleep Apnea (CSA)
Central sleep apnea is less common and occurs when the brain fails to send the appropriate signals to the muscles that control breathing. Unlike OSA, there is no physical blockage of the airway. Instead, CSA is caused by a problem with the brain’s respiratory control center. This type of sleep apnea often affects individuals with underlying medical conditions such as heart failure or stroke. CSA can lead to irregular breathing patterns and periods of no breathing during sleep, causing disrupted sleep and daytime fatigue.
Complex Sleep Apnea (ComSA)
Complex sleep apnea, also known as mixed sleep apnea, is a condition where both OSA and CSA are present. Initially, a person may experience obstructive sleep apnea, characterized by physical blockages in the airway. However, after beginning treatment for OSA, central sleep apnea can sometimes emerge. This occurs when the brain fails to send the correct signals to the muscles responsible for breathing. Effective management of complex sleep apnea requires addressing both types of apneas simultaneously. This often involves adjusting treatment approaches, such as using specialized machines, and regular monitoring to ensure both obstructive and central breathing issues are properly managed.
Symptom | Specific Manifestations |
Loud Snoring | Frequent, loud snoring is a common symptom, especially in obstructive sleep apnea. It may be accompanied by choking or gasping sounds. |
Excessive Daytime Sleepiness | Persistent drowsiness, fatigue, or the need to nap during the day despite having a full night’s sleep can indicate sleep apnea. |
Pauses in Breathing | Observed by a partner, these pauses can last for several seconds and are often followed by choking or gasping sounds. |
Restless Sleep | Frequent awakenings, restless tossing, or thrashing during sleep can be signs of disturbed sleep due to apnea. |
Morning Headaches | Waking up with headaches may be related to the poor sleep quality and oxygen deprivation associated with sleep apnea. |
Difficulty Concentrating | Problems with memory, concentration, and cognitive function can result from interrupted sleep and lack of restful sleep. |
Irritability and Mood Changes | Increased irritability, mood swings, or depression can occur due to chronic sleep disruption. |
Dry Mouth or Sore Throat | Waking up with a dry mouth or sore throat can be due to breathing through the mouth during sleep. |
The causes of different types of sleep apnea vary. Below are the primary causes of the three most common forms of sleep apnea today.
Obstructive Sleep Apnea (OSA)
Excess Weight: Obesity increases fat deposits around the neck and throat, leading to airway obstruction.
Large Tonsils or Adenoids: Enlarged tonsils or adenoids can block the airway, particularly in children.
Anatomical Features: Structural abnormalities such as a deviated septum, a large tongue, or a narrow throat can obstruct airflow.
Relaxed Throat Muscles: During sleep, the throat muscles may relax excessively, causing the airway to collapse.
Central Sleep Apnea (CSA)
Medical Conditions: Conditions such as heart failure, stroke, or neurological disorders can affect the brain’s ability to regulate breathing.
Heart Disorders: Certain heart conditions can influence the brain’s control of breathing patterns.
Stroke or Brain Injury: Damage to brain areas responsible for controlling breathing can lead to CSA.
Complex Sleep Apnea
Combination of Factors: This occurs when a person initially has OSA, and treatment for OSA leads to the emergence of CSA. It involves a combination of both obstructive and central sleep apnea causes.
