  • Fatigue is generally considered a more long-term condition than sleepiness (somnolence).[18] Although sleepiness can be a symptom of medical issues, it usually results from lack of restful sleep, or a lack of stimulation.[19] Chronic fatigue, on the other hand, is a symptom of a greater medical problem in most cases.
