Polysomnograms(PSG) --

or sleep studies are used to diagnose problems of excessive fatigue, sleepiness, snoring, or restless sleep. Patients are monitored while they sleep for brain wave patterns, eye movements, muscle tension, air flow and respiratory effort, oxygen levels and heart beat.

How do I get a sleep study?

A physician referral is needed to obtain a sleep study. Your family physician can provide this for you.

Before you talk to your doctor about a sleep study, it is a good idea to keep a 1-2 week journal of your sleep habits including the time you go to bed, how long it takes to fall asleep, the number of times you awaken during the night, the time you get out of bed in the morning, if you feel refreshed when you wake up and any naps taken or needed throughout the day.

Although you will spend the night, a sleep study is considered an outpatient procedure. Most insurance companies cover sleep studies but it is a good idea to check with your individual carrier.

You can obtain more information on a sleep diary on the National Sleep Foundation website. You can also call the MGHS sleep Lab at 906-225-3565 or 1-800-562-9753, extension 3565 for more information. You can also email us at sleeplab@mgh.org.

Irregular sleep patterns may contribute to overweight. The latest research on sleep deprivation shows a definite link between appetite control and lack of sleep, caused by hormonal changes. To find out more on weight management visit our weight management web site.
