Fatigue is a term used to describe a feeling of tiredness or lack of energy. It is a normal response to stress or physical exertion, but can also be a symptom of an underlying condition that requires medical attention. Fatigue may reduce the quality of life as affected individuals may be unable to function at work.

Fatigue can be due to certain lifestyle factors such as lack of activity or poor diet which get resolved through making changes in daily routine. However, if it is a symptom of an underlying disease, it should not be ignored for it may lead to serious medical conditions.
