Idiopathic Hypersomnia

Overview

Idiopathic hypersomnia (IH) is a sleep disorder where you have an excessive need to sleep. You wake up very tired even after getting an adequate amount of sleep. “Idiopathic” means the cause is unknown.

If you have idiopathic hypersomnia, you probably won’t feel rested when you wake up, even after more than nine hours of sleep at night. You may need to set several alarms and drag yourself out of bed in the morning. You might take an afternoon nap to help you feel more alert, but you still feel tired when you wake up. Feeling tired during the day can interfere with your ability to function as expected.

A healthcare provider can help you manage the symptoms of this type of hypersomnia.

How rare is idiopathic hypersomnia?

Idiopathic hypersomnia affects an estimated 10 people out of every 100,000 in the United States annually.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.

The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:

High blood pressure.
Diabetes.
Heart failure.
Some types of heart valve disease.

Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:

Control high blood pressure, high cholesterol and diabetes.
Don't smoke or use tobacco.
Eat a diet that's low in salt and saturated fat.
Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
Get good sleep. Adults should aim for 7 to 9 hours daily.
Maintain a healthy weight.
Reduce and manage stress.
