Sleep apnea: Do you have it?

Obstructive sleep apnea (OSA) is a disorder in which your breathing is repeatedly obstructed or restricted fully or partially for periods of 10 seconds or longer while you sleep. Although millions of people have sleep apnea, most don’t know it because the symptoms happen while they’re sleeping.

Obstructive sleep apnea occurs when the brain sends the signal to the muscles and the muscles make an effort to take a breath, but they are unsuccessful because the airway is blocked and prevents a good flow of air.

Sometimes the bed partner or a family member of a person with sleep apnea will tell them that they snore. While snoring is a good indicator of obstructive sleep apnea, there are other symptoms they should also be aware of.

obstructionSymptoms of obstructive sleep apnea

  • Loud or habitual snoring
  • Gasping for air
  • Pauses in breathing
  • Stoppages in breathing
  • Tossing and turning
  • Tiredness during the day
  • Frequent brief arousals

Why sleep apnea is serious

Sleep apnea deprives people of oxygen. Untreated sleep apnea can lead to:

  • High blood pressure, heart attack, stroke, obesity and diabetes
  • Heart failure
  • Irregular heartbeats (arrhythmias)
  • Extreme fatigue
  • Driving or work-related accidents
  • Headaches
  • Loss of interest in sex
  • Decline in mental functioning

What to do

Sleep apnea is potentially dangerous. The only way to determine if you have sleep apnea is to have a sleep study performed by a qualified sleep medicine physician who specializes in sleep disorders.

The sleep study records your brainwaves, breathing patterns, oxygen levels and other bodily functions as you sleep. The sleep medicine physician will read the results of this test, make a diagnosis and offer recommendations. He or she will also be able to recognize if you have a different medical condition.

Talk with your doctor to obtain a referral.

Treatment options for sleep apnea

If the sleep test results show that you have sleep apnea, your sleep medicine physician will determine which treatment is the best option for you:

At the University of Michigan Sleep Disorders Center, we work with hundreds of patients every year to determine whether they have sleep apnea or one of the other 100 sleep disorders. Sleep studies require two overnight stays in one of our comfortable at three locations. We also offer home sleep apnea studies and train our patients in how to do these effectively.

Sleep apnea doesn’t go away on its own. But the treatments are highly effective.

Alternatives to CPAP

While CPAP is the most common treatment for OSA, some people find that they cannot tolerate CPAP or prefer an alternative treatment. For those people, we have the highly successful Alternative to CPAP Clinic, which offers evaluations for oral appliance therapy and surgical treatments that would be appropriate for particular patients.

Other types of sleep apnea

There are two other types of sleep apnea: central and mixed. Central sleep apnea (CSA) occurs when the brain does not send signals to the muscles to take a breath, and there is no muscular effort to take a breath. This type of sleep apnea usually occurs when there are other serious medical conditions that may warrant further evaluation.

Mixed sleep apnea is when an individual has both obstructed sleep apnea and central sleep apnea.
