How to Cope with Fatigue

During and after cancer treatment, many feel fatigued. The most common side-effect of cancer treatment, fatigue often causes feelings of being tired, weak and lacking energy.

Much different than the tiredness a healthy person can experience, cancer-related fatigue does not improve with rest alone and can significantly reduce quality of life. Fatigue usually lessens when cancer treatment ends, but symptoms can still persist for a long time.

What is fatigue?

  • Physical or mental exhaustion
  • Having less energy to do things you normally do or want to do
  • Feeling heaviness in arms and legs
  • Unable to sleep or sleep too much
  • A common symptom with cancer or cancer treatment
  • Lasts for long periods of time, affecting daily activities
  • Not relieved by sleep or rest
  • Can vary in unpleasantness and intensity
Common causes of cancer-related fatigue include side effects of medications, anxiety, poor nutrition, lack of exercise, trouble sleeping, pain, anemia, difficulty of breathing, emotional distress and other illnesses in addition to cancer.

Do I need help? Ask yourself:

  • Am I too tired to do my normal activities?
  • Do I not have the energy to eat properly?
  • Do I have trouble thinking or concentrating?
  • Am I feeling isolated and depressed?
  • Do I have trouble following my treatment plan?
If you answered “yes” to any of these questions, talk to your doctor about how you’ve been feeling. Keep a diary or a log, including:
  • When did the fatigue start?
  • What makes the fatigue better or worse?
  • How has fatigue affected your daily routine or activities?  


There are several things you can do to manage fatigue including:
  • Sort out important activities from those that can wait
  • Perform activities during the times of day you tend to have more energy
  • Place items where you can easily reach them
  • Take breaks between tasks before becoming too tired
  • Set a regular bedtime for yourself
  • Whenever possible, perform tasks sitting rather than standing
  • Ask for help by asking friends and family to do things for you

Additionally, a daily workout routine can help by strengthening your muscles, keeping bones healthy and restoring joint flexibility. Ask your doctor or physical therapist about an exercise program.

  • Keep in mind that you might feel more tired after you first start exercising because your body is adapting, but don’t get discouraged.
  • Breathe properly while you exercise, inhaling and exhaling between movements.
  • Exercise slowly and completely, and pace yourself — don’t rush.
  • If you have muscle or joint pain lasting more than two hours, talk to your doctor or physical therapist about more gentle exercises.
