What Causes Sleep Apnea?
Sleep apnea can develop for a wide variety of reasons, and it falls into a couple of different types. Obstructive sleep apnea (OSA) is the most common, occurring when the airway is too narrow, blocked, or otherwise restricted. Central sleep apnea (CSA) is often linked to neurological issues that interfere with normal breathing signals. No matter the type, factors like weight, lifestyle, and family history can all play a contributing role.

With obstructive sleep apnea, the soft tissues in the throat relax and collapse during sleep, physically narrowing or blocking the airway. This is the type most closely associated with loud snoring and choking or gasping during the night. Learn more about obstructive sleep apnea treatment.
Central Sleep Apnea: A Different Root Cause
Central sleep apnea is less common and stems from the brain failing to send the proper signals to the muscles that control breathing, rather than a physical blockage. It’s often linked to underlying neurological or cardiac conditions and may require a different treatment approach than OSA.
Contributing Risk Factors
Regardless of type, several factors can increase your likelihood of developing sleep apnea, including excess weight, smoking or alcohol use, family history, and certain anatomical traits like a narrow airway or enlarged tonsils. If you recognize any of these risk factors alongside symptoms, review our page on common sleep apnea symptoms.
Frequently Asked Questions About What Causes Sleep Apnea
What’s the most common cause of sleep apnea?
The most common cause is obstructive sleep apnea, where the soft tissues of the throat relax and block the airway during sleep.
Can sleep apnea be genetic?
Family history can play a role, since certain anatomical traits that contribute to sleep apnea can be inherited.
Does being overweight cause sleep apnea?
Excess weight, particularly around the neck, is a significant risk factor, though sleep apnea can also occur in people who are not overweight.
Is central sleep apnea treated differently than obstructive sleep apnea?
Yes, since central sleep apnea stems from a different underlying cause, treatment often needs to address the related neurological or cardiac factors involved.
Can lifestyle changes reduce my risk of sleep apnea?
Yes, maintaining a healthy weight, limiting alcohol close to bedtime, and avoiding smoking can all help reduce risk.
