Overview

Fatigue is a feeling of tiredness, exhaustion, or lack of energy. You may feel fatigue because of too much or not enough activity. It can also come from stress, lack of sleep, boredom, and poor diet. Many medical problems, such as viral infections, can cause fatigue. Emotional problems, especially depression, are often the cause of fatigue.

Fatigue is most often a symptom of another problem. Treatment for fatigue depends on the cause. For example, if you have fatigue because you have a certain health problem, treating this problem also treats your fatigue. If depression or anxiety is the cause, treatment may help.
