Fatigue (cont.)

Since fatigue is a symptom of an underlying condition, the treatment depends upon the condition that is causing the fatigue, regardless of whether it is physical, psychological or a combination of the two.

There may be a lag time between when the illness has been treated and the intensity of fatigue symptoms; some symptoms may resolve as soon as the underlying condition is treated. For example, individuals who are anemic feel much better as soon as their red blood cell count increases, while those recovering from infectious mononucleosis may require weeks to have their energy levels return to normal.

Fatigue as a symptom can occur as the result of many causes and therefore, prevention is not an issue. More importantly, the early recognition of fatigue will allow a person to seek medical care and potentially have an earlier diagnosis of the underlying cause made.

Sometimes, symptoms like fatigue arise gradually and it is difficult for the person to realize that there is a problem. It may take an outside perspective from a friend or family member to appreciate a difference in function. Self-awareness of gradual decline in body performance is often difficult as a person makes repeated small accommodations to complete daily activities.
