Tiredness and Fatigue
General or Other | General Practice | Tiredness and Fatigue (Symptom)
Description
Fatigue in medical terminology, refers to the situation of reduced working capacity or achievement after a period of mental or physical activity. Fatigue is a symptom that defines a particular disease. Rather, fatigue can be a symptom of many diseases and conditions.
Causes
The range of underlying causes of fatigue is lack of sleep or the execution of exercises for medical and surgical treatments. The lack of energy associated with fatigue can sometimes cause difficulty with normal daily activities, leading to problems with attention and concentration.
The potential causes of fatigue are numerous. The majority of diseases known to man often list fatigue or malaise as possible associated symptoms. This is complicated by the fact that fatigue can occur in normal healthy individuals as a normal response to physical and mental exertion. However, normal fatigue may begin to become abnormal if it becomes chronic, extreme or prolonged fatigue; usually this occurs when a person experiences chronic or prolonged physical or mental exertion. For example, unusually hard physical or mental exertion for one day can result in normal fatigue that may last about a day or sometimes more, depending on the exertion level, while daily unusually hard physical or mental exertion may result in prolonged fatigue (usually greater than 24 to 48 hours). This latter situation may develop into abnormal fatigue.
