Fatigue is a common health complaint. It is, however, one of the hardest terms to define, and a symptom of many different conditions.
Fatigue, also known as weariness, tiredness, exhaustion, or lethargy, is generally defined as a feeling of lack of energy. Fatigue is not the same as drowsiness, but the desire to sleep may accompany fatigue. Apathy is a feeling of indifference that may accompany fatigue or exist independently.
Fatigue is common. Around 20% of Americans claim to have fatigue intense enough to interfere with their having a normal life. Physical causes are estimated at 20-60%, and emotional causes are the other 40-80%. The challenge is how to tell what is causing your fatigue and whether it is serious enough to see your doctor.
