Sleep-related breathing disorders are conditions that affect breathing patterns during sleep, leading to disruptions in restful sleep, which could then impact overall health. These disorders can range from mild to severe and may require medical intervention for management. Understanding the different types of sleep-related breathing disorders is crucial for proper diagnosis and treatment.

Obstructive sleep apnea

Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder. It occurs when the muscles at the back of the throat relax excessively during sleep, causing the airway to become blocked or narrowed. This results in pauses in breathing (apneas) or shallow breathing during sleep. Symptoms include loud snoring, daytime sleepiness and morning headaches.

Central sleep apnea

Central sleep apnea (CSA) is less common and occurs when the brain fails to send proper signals to the muscles that control breathing during sleep. Unlike OSA, there may not be a physical obstruction in the airway. CSA often presents with symptoms such as frequent awakenings during the night, shortness of breath and difficulty staying asleep.

Mixed sleep apnea

Mixed sleep apnea, also known as complex sleep apnea, is a combination of both obstructive and central sleep apnea. People struggling with mixed sleep apnea may exhibit symptoms of both types of apnea and often require specialized treatment approaches.

Upper airway resistance syndrome

Upper airway resistance syndrome (UARS) is characterized by increased resistance to airflow in the upper airway during sleep, leading to fragmented sleep and daytime fatigue. While similar to OSA, people with UARS may not experience full-blown apneas but rather frequent arousals from sleep due to increased effort to breathe.

Catathrenia

Catathrenia, also known as nocturnal groaning, is a rare sleep disorder characterized by involuntary groaning sounds during exhalation while asleep. Unlike snoring, it occurs during exhalation and is often not associated with other sleep disturbances. Its exact cause is not fully understood, but it typically does not require medical treatment.
