Fatigue Vs. Sleepiness
editFatigue is generally considered a more long term condition than Sleepiness (see Somnolence)[1]. Although sleepiness can be a symptom of medical issues, it usually results from lack of restful sleep, or a lack of stimulation [2]. Fatigue, on the other hand, is a symptom of a greater medical problem in most cases. It manifests in mental or physical weariness and inability to complete tasks at normal performance[3]. Both are often used interchangeably and even categorized under the description of 'being tired.'
