A sleep related breathing disorders definition describes conditions where respiration becomes abnormal or difficult during rest, including sleep apnea and chronic snoring.
Understanding Sleep Related Breathing Disorders
These conditions involve irregular breathing patterns ranging from harmless snoring to severe disruptions that alter blood oxygen and carbon dioxide levels. Because symptoms and causes vary, some patients may be diagnosed with multiple types of these disorders.
Obstructive Sleep Apnea (OSA)
In OSA, the airway collapses during sleep, causing breathing pauses that lower oxygen levels and disrupt sleep.
- Adults: This condition affects up to 30% of adults and is more frequent in men. Obesity is a primary risk factor.
- Children: This occurs in 1% to 5% of children. Unlike adults, pediatric cases are often caused by enlarged adenoids and tonsils.
Central Sleep Apnea (CSA)
CSA occurs when the brain fails to trigger the respiratory muscles or the muscles do not respond to those signals. It is less common than OSA, affecting fewer than 1% of people over 40, and is more frequent in men or those over 65.
Other Breathing Disruptions
- Sleep-related hypoventilation: Insufficient air movement leads to high carbon dioxide levels in the blood. This is often linked to COPD or obesity hypoventilation syndrome.
- Sleep-related hypoxemia: This condition is characterized by low blood oxygen levels without the high carbon dioxide levels seen in sleep-related hypoventilation.
- RERAs: Respiratory effort-related arousals are brief awakenings following at least 10 seconds of reduced nasal airflow. Unlike apneas, they do not cause blood oxygen to drop.
- Catathrenia: Also known as sleep groaning, this involves long inhalations followed by a monotone groan during exhalation.
Common Symptoms and Breathing Treatment
Treatment approaches depend on the specific diagnosis. For children with OSA, removing the tonsils and adenoids is common. For CSA and hypoventilation, doctors treat the underlying medical cause.
Chronic snoring happens when air vibrates floppy throat tissue. While occasional snoring is normal, it is considered a disorder if it happens more than three nights a week. Risk factors include alcohol use, nasal congestion, and sleeping on the back.
FAQ
What type of disorder is sleep apnea?
Sleep apnea is a serious breathing disorder where breathing repeatedly stops and starts. It can be obstructive, where the airway is blocked, or central, where the brain does not signal the muscles to breathe.
What causes breathing problems during sleep?
Causes vary by condition. OSA is often linked to obesity or enlarged throat tissues in children. CSA can be caused by heart problems, narcotic use, or high altitudes. Hypoventilation is frequently tied to lung diseases like COPD.
What Is a Respiratory Effort-Related Arousal (RERA)?
A RERA is a short awakening from sleep that occurs after nasal breathing decreases for 10 seconds or more. These are often detected during clinical sleep studies.
Who Gets Sleep-Related Eating Disorders?
These disorders, including night eating syndrome and nocturnal sleep-related eating disorder, affect both genders but are more common in women. They are more prevalent in people who also have other eating disorders.
When to See a Doctor
Consult a healthcare provider if you experience these warning signs:
- Excessive sleepiness during the day.
- Gasping or choking sounds while asleep.
- Morning headaches.
- Recent weight gain combined with chronic snoring.
- Teeth grinding during the night.
