Managing Fatigue
What is fatigue?
Fatigue is one of the most common side effects of cancer treatment. It can be caused by surgery, chemotherapy, radiation therapy, or other medications used to treat your cancer. It is a feeling of exhaustion, feeling completely worn out, feeling that your body is "heavy" and hard to move, or being unable to focus. Fatigue can cause physical, emotional, and mental exhaustion.
Cancer-related fatigue is not caused by too much activity and often does not go away with rest. Healthcare providers do not know exactly what causes cancer-related fatigue. It likely has a few different causes, which makes it hard to treat.
It has been found that treating anemia and exercising can help manage fatigue. There are other ways to manage fatigue as well. Talk to your provider about your fatigue and possible treatments.
Exercise
Exercise has been shown to improve fatigue and quality of life.
- Start slow if needed, maybe with a walk around the block, then add time or distance as you feel more comfortable.
- Having a buddy to exercise with can help motivate you and make it more enjoyable.
- Try to include endurance (walking, jogging, swimming) and resistance (weights, Pilates) exercises.
- A cancer rehabilitation program or physical therapist can help you make a plan that works for you.
Treatment of Anemia
Anemia happens when the level of red blood cells (hemoglobin) in your body is too low. Hemoglobin helps carry oxygen throughout the body. This oxygen is the fuel for muscles, and low levels of it can lead to fatigue.
- Treatment for anemia depends on the cause and your symptoms. Possible treatments are iron pills, red blood cell transfusion, or growth factors to help make red blood cells.
- Your healthcare provider can talk with you about which treatment, if any, is right for you.
Other Tips for Managing Fatigue
- Allow yourself to rest and create a sleep schedule. Too much rest can make fatigue worse, so keep your rest times to 45-60 minutes. Try to keep a normal sleep schedule (go to bed and wake up at the same time), limit naps to 45-60 minutes, avoid caffeine, and talk to your provider about a sleep aid if you are having trouble.
- Save up energy for when you need or want it most. If there is something you want to do in the afternoon, make sure you take time to rest in the morning and evening. Avoid tasks that you do not have to do.
- Ask for help! People want to help, they just don't always know what to do. Ask a friend to clean, prepare a meal, run an errand, or just sit and talk. Think about the person's personality and strengths when asking for help and accept that they may do it differently than you.
- Keep track of your bad days. If you know the day after treatment is a bad day, don't make plans for that day. If you work every day, schedule treatment on Friday afternoon to give you the weekend to rest.
- Let friends and family know that even if you make plans, there will be some days when you just can't do it and may have to cancel or change plans.
- Be sure to eat a balanced diet with carbohydrates and proteins for energy, avoid heavy fatty meals, and try 4 or 5 smaller meals as opposed to 3 larger ones.
- Make time for activities that energize you like visiting with friends, having a meal out, listening to music, or doing a hobby you enjoy.
- You may be able to change your work schedule while you are receiving treatment. Talk to human resources about the Americans with Disabilities or Family Medical Leave Acts, sick time, and healthcare coverage.
- Complementary therapies such as massage, relaxation techniques, meditation, and yoga can help relieve fatigue.
- If you are having pain, proper pain management can help with fatigue.
- Ask how to manage other side effects of treatment that are affecting your sleep, like nausea, vomiting, diarrhea, mucositis, and skin issues.
Be sure to let your care team know if you are not getting any relief from fatigue or if you begin to feel depressed, feel a loss of interest, or have increased anxiety, as these could be a sign of other issues.
