Fatigue is one of the most common side effects of cancer treatment. It can occur during cancer treatment or linger long after treatment has ended. When sleep and rest are not effective, it’s time to talk with your doctor. Your chronic feeling may be linked to anemia, which is when there are not enough red blood cells in your body. Poor nutrition from a loss of appetite, dehydration, abnormal hormone levels and some medications also may be causes of fatigue. Ongoing emotional anxiety, pain, or memory issues are other potential factors for chronic fatigue.

Your cancer care team can check for medical causes and talk with you about several ways to minimize fatigue, such as

  • Physical therapy and exercises that can help you increase your overall health and energy level.
  • Nutrition counseling with a certified dietitian to address any loss of appetite.
  • Blood transfusions to treat anemia.
  • Medications and coping strategies to deal with depression, anxiety, or pain
