There are several types of sleep apnea, which depend on the cause. In this case:

  • Central sleep apnea (CSA) occurs when your brain temporarily stops sending the correct signals to the rest of your body to regulate your breathing.
  • Obstructive sleep apnea (OSA) is due to a physical obstruction — commonly the tongue — in the mouth or throat that inhibits your ability to breathe correctly.

CSA can have few or no symptoms beyond daytime fatigue. OSA tends to create further symptoms like snoring, headaches, and dry mouth.

OSA is much more common than CSA.

Is obstructive sleep apnea worse than central sleep apnea?

While CSA is much rarer than OSA, some studies have found that it has a higher risk of life threatening complications.

Because central sleep apnea can often present no symptoms, those who have it may be unaware and, therefore, unable to get the treatment that they need.

Both OSA and CSA can cause:

Many sleep disorders have overlapping symptoms and causes that only a medical professional can diagnose.

A CPAP machine can help treat both CSA and OSA.

Treatment for OSA can also involve medications, oral appliances, or surgery. Your primary healthcare professional will have the best information on what treatment plans are best for you.

Bottom line

Obstructive sleep apnea is due to something blocking your breathing pathway, and central sleep apnea is where your brain temporarily stops sending the signal to your body to breathe.

Obstructive sleep apnea is more common, while central sleep apnea is much rarer.

Both conditions can cause trouble sleeping, and treatment involves the use of a CPAP machine. Obstructive sleep apnea tends to have a wider variety of symptoms and more treatment options.
