Is it hard for you to fall asleep? Do you wake up feeling unrested? Do you snore, or wake up multiple times during the night? We can help you find peace and more restful nights.

Sleep occupies a vital portion a person’s life. Research shows that an adequate amount is essential for good health. While many people fall asleep at night with ease and wake up refreshed for the next day, not everyone is so lucky. Up to 30 percent of the general population suffers from some form of sleep disorder.

The Sleep Diagnostic Center in NorthCrest Medical Center is devoted to diagnosing some of the most common types of sleep disorders, those that are related to disorders of breathing during sleep. Someone experiencing the signs and symptoms of a sleep disorder should speak with their primary care provider (PCP) about the possibility of having a sleep disorder and undergoing a sleep study.

Signs and symptoms:

  • Snoring
  • Excessive daytime sleepiness
  • Choking sensation at night
  • Fatigue
  • Insomnia
  • Fitful sleep (frequent awakenings)
  • Shortness of breath
  • Chest pain
  • Irritability, anxiety, depression
  • High blood pressure
  • Morning headaches
  • Loss of interest (in hobbies, sex, etc.)
  • Trouble concentrating
  • Weight gain

Individuals who may benefit from a sleep study are those who have chronic problems falling asleep, staying asleep at night or staying awake during the day, as well as those who suffer from excessive snoring or breathing disturbances. The sleep lab is capable of monitoring adults, adolescents and children. We offer day-time testing for 3rd-shift workers.

Sleep Apnea and Snoring

Snoring is not always just a normal, annoying occurrence. Snoring may be a symptom of a serious sleep disorder called sleep apnea. People with sleep apnea have pauses in breathing during sleep that end with arousal (waking up), which may interrupt what would otherwise be a good, refreshing night of sleep.

Those with sleep apnea may experience loud snoring, choking, and gasping as they struggle to breathe again. These episodes may occur several times a night. While snoring represents abnormal breathing during sleep and is the result of a partial collapse of the air passage in the throat, sleep apnea is described as a complete or near-complete obstruction to airflow.

Often people with sleep apnea are unaware of any problems while sleeping, but awaken feeling poorly and tired. This excessive sleepiness may affect other aspects of life including poor job performance due to fatigue and falling asleep at inappropriate times like during work or while driving a vehicle.

If untreated, sleep apnea can cause people to experience symptoms such as shortness of breath and chest pain. Also, it may lead to high blood pressure, headaches, and an increased risk for heart attack or stroke. If you experience any of these symptoms, you may want to talk with your primary care provider (PCP) about sleep apnea.


Insomnia is the inability to sleep and/or abnormal wakefulness. Symptoms include:

  • Depression or stress
  • Disturbing thoughts while trying to sleep
  • Waking during the night with difficulty going back to sleep
  • Lying awake for more than half an hour before falling asleep


Narcolepsy is a condition marked by an uncontrollable desire for sleep, or sudden attacks of weakness occurring during moments of strong emotions. Related symptoms and warning signs include:

  • Vivid nightmares or hallucinations when falling asleep or waking up
  • Paralysis when falling asleep or awakening
  • A feeling of ‘going limp’ when angry or surprised
  • Excessive daytime sleepiness
  • Disturbed or fragmented sleep

Testing at the Sleep Diagnostic Center does require a referral from your primary care provider. If you think you could benefit from a sleep study, don’t hesitate to tell your PCP – questions can be referred to the Sleep Diagnostic Center at 615-382-5698.

Many insurance plans cover sleep disorder testing, however, please call your insurance company and verify your benefits, coverage, and the need for any authorizations prior to your date of service. Prior to testing, it is important to know:

  • If NorthCrest is within your insurance network
  • If sleep studies are covered under your insurance
  • All necessary referrals, authorizations, or precertification’s have been received by NorthCrest or your insurance carrier
  • If uninsured: speak to a financial counselor at 615-384-1546 for your financial options

Registration before your test: We recommend our patients preregister prior to the date of study by calling the Outpatient Registration department at NorthCrest Medical Center at 615-384-1546.
