Daytime sleepiness can sometimes be a sign of an underlying condition, like idiopathic hypersomnia (IH). Answer these questions to determine whether you should talk with your doctor about IH.

Sleepiness is a pretty common issue. You may find you’re extra tired for a variety of mundane reasons, such as staying up late preparing a work presentation or helping a young child.

Or maybe you stayed out late partying or watched a series on your favorite streaming service.

If you feel tired after a late night or when you’re stressed, you will probably start to feel better once you get enough sleep. Sometimes, though, excessive daytime sleepiness may be a sign of something more serious.

Idiopathic hypersomnia (IH) is a type of neurological sleep disorder associated with trouble staying alert and awake during the day, among other symptoms.

Answer these questions to check your sleep concerns and determine whether speaking with a healthcare professional about sleepiness may be a good next step.
