Fatigue (definition of)

Fatigue is a state of weakness, exhaustion, weariness, lassitude, and a reduced ability to function physically. "Acute fatigue" is normal after periods of exertion or loss of sleep. However, "chronic fatigue" is an ongoing condition that can interfere with the quality of life.

Cancer victims, including those diagnosed with mesothelioma (like peritoneal mesothelioma or pericardial mesothelioma), often experience chronic fatigue. This is not only due to the disease itself, but to the treatments as well; fatigue is often the result of weight loss, breathing difficulty, insomnia, anemia, hormonal changes and loss of appetite, all of which are associated with cancer as well as radiation treatments and chemotherapy. Fatigue can also result from anxiety and depression that is part of dealing with cancer like asbestos cancer.

Because fatigue has numerous causes that are unique to each individual case, there are no standard approaches for dealing with it. Medications such as antidepressants or stimulants may be helpful; exercise, cognitive behavior therapy and rest are also indicated.
