Everyone experiences fatigue periodically as a result of hard physical labor or loss of sleep. Fatigue, loss of energy, and lassitude are common symptoms experienced by patients with any one of a large number of diseases. A patient who complains of chronic fatigue presents a difficult problem for the family physician because there are many possible explanations for the fatigue. This difficulty is compounded by the subjective nature of the complaint and the potential seriousness of some of the diseases in the differential diagnosis.
