Fatigue—feeling tired and lacking energy—is a common symptom reported by cancer patients. The exact cause is not always known. It can be due to your disease, chemotherapy, radiation, surgery, low blood counts, lack of sleep, pain, stress, and poor appetite, along with many other factors.
Fatigue from chemotherapy feels different from fatigue of everyday life. Fatigue caused by chemotherapy can appear suddenly. Patients with cancer have described it as a total lack of energy and have used words such as worn out, drained, and wiped out to describe their fatigue. Rest does not always relieve it. Not everyone feels the same kind of fatigue. It can last days, weeks, or even months.
Here are some tips on coping with fatigue:
