Sleep apnea

Signs & symptoms

Obstructive sleep apnea is a serious breathing problem that interrupts your sleep.

The two main symptoms of obstructive sleep apnea are:

  • You’re very sleepy during the day, but you don’t know why.
  • You snore and have pauses in your breathing while sleeping.

Some other signs and symptoms of obstructive sleep apnea:

  • You have high blood pressure 1
  • You’re irritable.
  • You gasp or choke during sleep.
  • You’re very tired (you have fatigue).
  • You’re depressed.
  • You can’t concentrate.
  • You have morning headaches.
  • You have memory problems/ memory loss.
  • For men: you have impotence (difficulty keeping an erection)

If you think you have these signs and symptoms or if you think you have sleep apnea, see your doctor. Your doctor can learn more about your symptoms and give you a test that helps diagnose sleep apnea.

Many people have sleep apnea without knowing it. Sleep apnea can develop slowly, over time. Many people don’t recognize the signs and symptoms.

Often people go to the doctor because they don’t know why they are so tired, or because their bed partner complains that they snore too much. These are clues that a person might have sleep apnea. Family members or bed partners often pick up on the signs of sleep apnea first. Many people with sleep apnea don't know they're snoring and gasping for breath at night.

The main symptom of sleep apnea is “excessive daytime sleepiness” – you are sleepier than expected during the day. Take this interactive quiz to find out your level of daytime sleepiness. You can share your quiz results with your doctor, who can do further tests to see if you have sleep apnea.
