Causes

Common Causes

Fatigue is typically the result of working, mental stress, jet lag or active recreation, depression, and also boredom, disease and lack of sleep. It may also have chemical causes, such as poisoning or mineral or vitamin deficiencies.

Diseases

Temporary fatigue is likely to be e.g. common cold. Chronic fatigue, on the other hand, meaning of six months or more duration, is a symptom of a large number of different diseases on conditions.

Medications

• Beta blocker medication causes fatigue, especially after exertion, inducing exercise intolerance.
