If your oversleeping pattern extends up to six weeks and beyond, it may be an indication of an underlying medical issue that may make such changes in your sleeping pattern. It is vital that you get yourself thoroughly examined to establish the actual cause of oversleeping. Your doctor may recommend some tests and may even ask you to go in for a sleep study. If there are no evident medical issues associated with oversleeping, your doctor may suggest the following diagnosis techniques:

1. Polysomnogram Test

You will be required to stay in the clinic or sleep centre, and various instruments will monitor your heart rate, brain activity, leg movements, eye movements etc.

2. Epworth Sleepiness Scale

Your doctor may measure your sleepiness on this scale to establish how your sleep could be affecting your day to day functioning.

3. Multiple Sleep Latency Tests

In addition to or after your polysomnogram test, your doctor may recommend multiple sleep latency tests to have a more comprehensive view of your sleep pattern and how you nap during the day.

4. Maintain a Dairy

Your doctor may even ask you to maintain a diary of your sleeping pattern, that is when you sleep when you get up, how many naps in a day you take, etc.
