“Fatigue” describes an overwhelming sense of exhaustion or extreme tiredness, and a lack of energy or depletion of reserves. Fatigue is inherently subjective; this means that one person may experience fatigue in a different way to the next. Fatigue can be thought of as being on a continuum from normal fatigue, which arises after exertion and remits with rest, to problematic fatigue, which does not necessarily arise from exertion, does not remit with rest, and interferes significantly with functioning. At the extreme end of the continuum is chronic fatigue syndrome (CFS), which is diagnosed in a child or adolescent who has experienced substantial and disabling fatigue for at least 3 months, for which there is no alternative medical explanation (NICE 2007). Fatigue is often associated with chronic diseases. Nevertheless management strategies which regularise activity and sleep can help reduce fatigue and improve quality of life.
