What is sleep apnea?

Sleep apnea is a condition that affects a person’s breathing while they sleep. This can affect how much oxygen reaches the brain and other parts of the body.

What are the different types of sleep apnea?

The different types of sleep apnea include:

  • Obstructive sleep apnea (OSA) is the most common. OSA is when the soft tissue in the back of the throat blocks the air going in and out of the throat.
  • Central sleep apnea is less common than OSA. This is when the brain does not tell the muscles that control breathing to work properly.
  • Complex sleep apnea syndrome is when a person has both OSA and central sleep apnea.

What are the risk factors for sleep apnea?

The risk factors for OSA include:

  • Enlarged tonsils and adenoids
  • Being overweight or obese
  • Family history of sleep apnea
  • Low muscle tone caused by medical conditions such as Down syndrome and muscular dystrophy
  • Certain medical conditions that cause changes to the shape of the face, such as Crouzon Syndrome and Pierre-Robin sequence

The risk factors for central sleep apnea include:

  • Neurological (brain and nerve) disorders such as Chiari malformation
  • Heart disorders
  • Using opioids (prescription pain medications)
