Doctors might not detect sleep problems during routine office visits because patients are awake. Thus, you should let your doctor know if you think you might have a sleep problem.
For example, talk with your doctor if you often feel sleepy during the day, don't wake up feeling refreshed and alert, or are having trouble adapting to shift work.
To get a better sense of your sleep problem, your doctor will ask you about your sleep habits. Before you see the doctor, think about how to describe your problems, including:
Your doctor also may ask questions about your personal routine and habits. For example, he or she may ask about your work and exercise routines. Your doctor also may ask whether you use caffeine, tobacco, alcohol, or any medicines (including over-the-counter medicines).
To help your doctor, consider keeping a sleep diary for a couple of weeks. Write down when you go to sleep, wake up, and take naps. (For example, you might note: Went to bed at 10 a.m.; woke up at 3 a.m. and couldn't fall back asleep; napped after work for 2 hours.)
Also write down how much you sleep each night, how alert and rested you feel in the morning, as well as how sleepy you feel at various times during the day. Share the information in your sleep diary with your doctor. You can find a sample sleep diary in the National Heart, Lung, and Blood Institute's "Your Guide to Healthy Sleep."
Doctors can diagnose some sleep disorders by asking questions about sleep schedules and habits and by getting information from sleep partners or parents. To diagnose other sleep disorders, doctors also use the results from sleep studies and other medical tests.
Sleep studies allow your doctor to measure how much and how well you sleep. They also help show whether you have sleep problems and how severe they are. For more information, go to the Health Topics Sleep Studies article.
Your doctor will do a physical exam to rule out other medical problems that might interfere with sleep. You may need blood tests to check for thyroid problems or other conditions that can cause sleep problems.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Sleep Deprivation and Deficiency, visit www.clinicaltrials.gov.
