Why We Perform Sleep Studies
Your doctor may recommend a sleep test if you have difficulty falling asleep, staying asleep, or if you feel excessively tired during the day. Chronic sleep disorders, such as sleep apnea, increase your risk of developing heart disease and other conditions.
You might be a good candidate for a sleep study if you have one or more of these symptoms:
- Trouble falling asleep
- Waking in the middle of the night for prolonged periods or waking earlier than desired
- Crawling or tingling feeling in your legs, particularly when you are relaxing or dozing off
- Jerking leg or arm movements as you sleep
- Chronic snoring or interruptions in breathing as you snore
- Ongoing daytime sleepiness
What to Expect from a Sleep Study
You’ll likely spend a night or day at a sleep center. In some cases, you may be given special monitoring equipment that you can wear at home while you sleep. Before your sleep study, your doctor will ask you to avoid caffeine or alcohol.
Types of sleep studies include:
- Portable home sleep monitor — a type of at-home sleep study
- Maintenance of wakefulness test (MWT) — a test to assess your ability to stay awake during the day
- Polysomnogram (PSG) — a test to diagnose disorders like sleep apnea
- Multiple sleep latency test (MSLT) — a daytime test typically performed after a PSG
During a sleep study, a technician or sleep specialist places sticky electrodes on your body. These record your breathing, movements, and blood oxygen levels.
If your test is performed at a sleep center, you’ll be able to go home as soon as the test is complete. If you have it at home, you’ll need to return the monitoring equipment to your doctor to receive a diagnosis.
What Your Sleep Diagnosis Means
Your provider will let you know your results typically within a few weeks. Your diagnosis will guide your treatment options.
Common conditions diagnosed with a sleep study include:
- Restless legs syndrome — sensations often relieved by moving your legs
- Narcolepsy — sudden and unexpected daytime sleepiness
- Sleep apnea — multiple pauses in breathing
Together with your doctor, you can create a personalized treatment plan that meets your needs. Dignity Health doctors provide thorough sleep study and sleep diagnosis in Southern California.
