What Are the Signs and Symptoms of Sleep Apnea?

Major Signs and Symptoms

One of the most common signs of obstructive sleep apnea is loud and chronic (ongoing) snoring. Pauses may occur in the snoring. Choking or gasping may follow the pauses.

The snoring usually is loudest when you sleep on your back; it might be less noisy when you turn on your side. You might not snore every night. Over time, however, the snoring can happen more often and get louder.

You're asleep when the snoring or gasping happens. You likely won't know that you're having problems breathing or be able to judge how severe the problem is. A family member or bed partner often will notice these problems before you do.

Not everyone who snores has sleep apnea.

Another common sign of sleep apnea is fighting sleepiness during the day, at work, or while driving. You may find yourself rapidly falling asleep during the quiet moments of the day when you're not active. Even if you don't have daytime sleepiness, talk with your doctor if you have problems breathing during sleep.

Other Signs and Symptoms

Others signs and symptoms of sleep apnea include:

  • Morning headaches
  • Memory or learning problems and not being able to concentrate
  • Feeling irritable, depressed, or having mood swings or personality changes
  • Waking up frequently to urinate
  • Dry mouth or sore throat when you wake up

In children, sleep apnea can cause hyperactivity, poor school performance, and angry or hostile behavior. Children who have sleep apnea also may breathe through their mouths instead of their noses during the day.
