Sleep Apnea Q & A

What causes sleep apnea?

There are two types of sleep apnea. In both types, you stop repeatedly breathing while you sleep. However, they have different causes.


Obstructive sleep apnea (OSA)

OSA occurs when soft tissues in your mouth and throat relax and fall back or over the airway at the back of your throat. The problem most often occurs when your tongue falls backward, but the airway can also become blocked due to enlarged tonsils and adenoids, and excessive fat tissue around your throat.


Central sleep apnea

Central sleep apnea, which is less common than OSA, develops when your brain doesn’t send the right signals to the muscles that control your breathing. This type of sleep apnea is often caused by an underlying problem like heart failure or a stroke. Opioid medications and being at a very high altitude can also trigger central sleep apnea.

What symptoms develop due to sleep apnea?

If you experience any of these symptoms, it’s important to schedule an evaluation because untreated sleep apnea leads to complications like high blood pressure and heart arrhythmias.

Symptoms of obstructive sleep apnea:

  • Loud snoring is the top symptom of OSA
  • Daytime fatigue
  • Morning headache
  • Difficulty with memory or concentration
  • Frequently going to the bathroom at night

Symptoms of central sleep apnea:

  • Waking with shortness of breath
  • Shortness of breath that improves when you sit up
  • Difficulty falling asleep
  • Excessive daytime sleepiness
  • Chest pain at night
  • Difficulty concentrating
  • Mood changes

Patients with central sleep apnea may also snore, but it’s not a predominant symptom.

How is sleep apnea diagnosed?

The only way to diagnose sleep apnea is with a sleep study. Dr. Shayya offers home sleep studies for patients who may have OSA. During a home sleep study, you wear sensors that record your oxygen levels, breathing, and air flow while you sleep.

If Dr. Shayya suspects central apnea, however, he may recommend that you go to a specialized sleep lab, where more detailed information is collected. Airflow isn’t usually blocked in central apnea, so it’s important to go to the sleep lab so they can monitor your heart rate and rhythm, brain waves, muscle movements, and sleep stages.

How is sleep apnea treated?

Both types of sleep apnea are treated with continuous positive airway pressure (CPAP). While CPAP is the gold standard of treatment for OSA, it’s just one of several possible treatments for central sleep apnea.

When you have central sleep apnea, the underlying condition is treated. Additionally, your apnea episodes may be treated with CPAP, adaptive servo-ventilation, bilevel positive airway pressure, supplemental oxygen, or medications that stimulate breathing while you sleep.
