Fatigue is one of the most common side effects of cancer treatment. It is described as a feeling of exhaustion, being worn out, inability to focus, and difficulty moving—the body may feel “heavy.” Fatigue from cancer treatment likely has multiple causes, but because there are so many, none have been identified specifically.
The two best ways to treat fatigue are exercise and medication for anemia. Anemia is a condition that is indicated by a low red blood cell count. Hemoglobin, an important element of red blood cells, carries oxygen throughout the body, and limited oxygenation can cause fatigue. Treatment depends on the severity and cause of the anemia. Light to moderate exercises, such as walking, jogging, swimming, gardening, or Pilates, have been shown to help with fatigue and quality of life.
