Hypersomnia – persistent fatigue and excessive drowsiness

Hypersomnia is a condition in which a person experiences a constant desire to sleep or excessive drowsiness during the day, even if the night’s sleep has been sufficient. It’s not just fatigue — hypersomnia has a significant impact on the ability to focus, work and live an active life.

Symptoms

  • Hard to wake up in the morning, even after a long nap
  • Falling asleep frequently during the day, including during conversations or activities
  • Persistent fatigue, apathy, difficulty concentrating
  • Memory degradation and irritability
  • Sometimes headaches and bad mood

Possible causes

Hypersomnia may be caused by:

  • primary sleep disorders: narcolepsy, idiopathic hypersomnia;
  • other neurological diseases – brain damage, stroke effects, etc.;
  • endocrines and metabolic disorders – thyroid diseases, diabetes mellitus, etc.
  • mental conditions – depression, anxiety, etc.;
  • drug effects or alcohol consumption.

Why do I need a sleep disorder diagnosis?

Hypersomnia is not just a lifestyle characteristic – it can be a symptom of a more serious illness. Accurate diagnosis helps determine the cause and opt for effective treatment.
