Fatigue is a term used to to describe the general overall feeling of tiredness and/or a lack of energy. Other words that are sometimes used in place of fatigue include exhaustion, weariness, and lethargy. Feeling fatigued is not the same different from just feeling drowsy or sleepy. When you are fatigued, you have no motivation and no energy. Being sleepy may be a symptom of fatigue, but it is not the same thing.

Scientists state that fatigue is a very common symptom for a number of medical conditions-both serious and non-serious-and also a natural result of some lifestyle choices. If your fatigue has no apparent cause, and it not going away with proper rest and nutrition, you should see your doctor. He or she can help to diagnose what is causing your fatigue and work with you to treat it.
