Exhaustion in cancer is defined as a persistent intense feeling of tiredness. This exhaustion cannot be compared with “normal tiredness” and similarly cannot be relieved by more sleep. The exhaustion interferes considerably with daily living.
Exhaustion can be brought on by the disease and the treatments. Anaemia, malnutrition, thyroid disorders, pain, nausea, emotional distress or alcohol and drug use can additionally worsen the exhaustion.
The fatigue should be examined by a doctor to determine the cause and treat it if possible. If no cause is found, measures can be taken to reduce it.
Usually, the fatigue gradually decreases after the therapies are completed. However, persistent fatigue is not a sign of disease progression.
