Causes of Sleep Apnea
If there is snoring, then the sleep apnea is likely to be related to an obstruction or an anatomical abnormality causing airway blockage. Without snoring, causes related to neurological disorders are more likely, or it may also be idiopathic sleep apnea.
Airway Blockages: Causes of sleep apnea include:
- Enlarged adenoids (adenoiditis)
- Enlarged tonsils
- Enlarged tongue
- Obstructive Sleep Apnea
- Obesity Hypoventilation Syndrome (Pickwickian syndrome)
Nasopharyngeal Abnormality: Various anatomical abnormalities of the oral region may cause sleep apnea:
- Deviated nasal septum (nasal structure abnormality)
- Cleft palate
- Abnormal large tongue (e.g. Down Syndrome)
Neurological Disorders: Disorders of the brain or CNS may affect the body’s breathing controls, causing apnea during sleep (even without any airway obstructions), which is called “central sleep apnea”:
- Brainstem tumor
- Shy-Drager syndrome
