Fatigue leads to physical disease if left untreated!
Chronic fatigue (syndrome) is a subjective symptom with a very imprecise definition, making it difficult to determine whether the condition is present or not. All other potential medical causes of fatigue must be excluded, and the accompanying symptoms must be specific. If fatigue lasts longer than a month, it is referred to as 'persistent fatigue,' and if it lasts longer than six months, it is referred to as 'chronic fatigue.' The majority of normal fatigue symptoms that anyone may experience are transient and disappear with rest; however, chronic fatigue that lasts for more than six months does not improve with rest and leaves the patient severely impaired. In general, chronic fatigue is four times more prevalent in women than in men, and it occurs most frequently in young adults between the ages of 25 and 45, though it can also affect children and the middle-aged. Therefore, self-diagnosis is required to monitor and manage one's condition continuously.
