In order to treat the lack of blood (anaemia), either red blood cells are administered to the body in a transfusion or the body’s own production of red blood cells is stimulated with hormones. Both methods lead to a quick multiplication of oxygen in the blood and, for this reason, to an increase of a person’s energy and productivity.

If the fatigue is caused by muscle weaknesses, a systematic exercise programme can be used for therapy. Endurance sports like jogging, swimming and cycling are effective means of exercise for fatigue patients.

“Fatigue” is the French word for tiredness or exhaustion and is also being called languidness or lassitude. It designates an exhaustion symptom which occurs with chronic diseases. As it is perceived by the patient and not visually noticeable to others it is a symptom opposed to a medical sign and primarily used in connection with cancer. It describes a feeling of sustained tiredness and listlessness that has an impact on the daily life of the concerned persons. In despite of sufficient sleep the patient feels weak, exhausted and overstrained.

Fatigue appears as a symptom of several diseases. It is mostly mentioned in the context of cancer. Other diseases which cause fatigue are autoimmune diseases, chronic infections and mental disorders. Besides the physical impact of these diseases the often long-term and exhausting therapeutic measures are responsible for the genesis of fatigue.

The cause of fatigue is being seen as a combination of multiple facts and therefore develops for different reasons. The treatment of an illness can cause changes of the metabolism, the hormone level and brain functions.
