Sometimes fatigue is just a consequence of not getting enough sleep, while other times it's a symptom of a problem like sleep apnea. However, there are times when fatigue is an actual disability. Chronic fatigue, also called chronic fatigue syndrome, is considered a disability that can qualify for disability benefits. Because the condition is chronic, it may not go away, but there are ways to relieve the symptoms. With regular cases of fatigue, treatment is very possible.
