When to Seek Medical Attention
Hypersomnia should be medically assessed when excessive daytime sleepiness persists, interferes with daily functioning, or causes unintended sleep episodes. Seek prompt evaluation when sleepiness is worsening or creates safety problems. Urgent assessment is appropriate when sudden severe sleepiness is accompanied by confusion, neurological symptoms, difficulty staying awake, or other concerning changes.

Symptoms 2
Excessive Sleepiness
Increased Urination
Causes 1
Possible causes include insufficient or disrupted nighttime sleep, sleep apnea and other sleep disorders, depression and other medical conditions, certain medicines or substances, neurological disorders, and disturbances of the body clock. Some people have central disorders of hypersomnolence in which excessive sleepiness persists despite adequate opportunity for sleep.
Chronic Disease
Risk Factors
Risk depends on the underlying cause and may include chronic sleep deprivation, irregular work schedules, sleep disorders, certain medicines, alcohol or other substances, neurological or psychiatric conditions, and family history of sleep-related disorders.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis begins with a detailed sleep history, assessment of daytime sleepiness, medication and substance review, and evaluation for medical or psychological causes. A sleep diary, sleep questionnaires, overnight polysomnography, multiple sleep latency testing, or other specialized investigations may be used when a primary sleep disorder is suspected.
Prevention
Key Prevention Tips
Maintaining a regular sleep schedule, allowing adequate time for nighttime sleep, limiting substances that disrupt sleep, treating sleep apnea and other underlying conditions, and reviewing medicines that cause excessive sleepiness may reduce preventable daytime sleepiness
Persistent or severe sleepiness should be medically evaluated, particularly when it affects driving or other safety-sensitive activities
Prevention Guidance
Maintaining a regular sleep schedule, allowing adequate time for nighttime sleep, limiting substances that disrupt sleep, treating sleep apnea and other underlying conditions, and reviewing medicines that cause excessive sleepiness may reduce preventable daytime sleepiness. Persistent or severe sleepiness should be medically evaluated, particularly when it affects driving or other safety-sensitive activities.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
