Fighting Fatigue
by Ellen Manzullo MD, FACP
Plan to do your most important activities
during periods of the day when you have the
most energy.
Fatigue is the most common and often most distressing symptom in cancer survivors. Cancer-related fatigue is different from the fatigue we all experience in daily living. Cancer-related fatigue can occur suddenly and can be overwhelming. You may experience weakness over the entire body or lack the energy to perform normal activities of daily living. Some people wake up tired after a normal night of sleep.
Cancer-related fatigue can also be mental, as well as emotional. At times, fatigue may cause you to have trouble concentrating and can make performing daily tasks difficult. A person who is emotionally fatigued might experience difficulty in relationships with family and friends. It is important to note that some people may experience cancer-related fatigue even years after completing cancer treatment.
There are many possible causes for cancer-related fatigue. It can be caused by cancer and by cancer treatments. It can also be a sign of an undiagnosed medical condition, or one that is being inadequately treated. For example, heart disease, hypothyroidism, and anemia can all result in the sensation of fatigue. Individuals with depression, uncontrolled pain, and insomnia can also experience fatigue. Fatigue has many possible causes, and there is often more than one cause in an individual. Although cancer-related fatigue can be overwhelming, several strategies can be used to fight fatigue.
It is important to pace yourself and avoid becoming overtired.
Energy Conservation Measures
If you are experiencing cancer-related
fatigue, there are many things you can
do to conserve your energy. First, prioritize
your most important activities
and plan to do them during periods of
the day when you have the most energy.
Routine tasks can be scheduled throughout
the week. It is important to pace
yourself and avoid becoming overtired.
When possible, delegate chores such
as strenuous housework, shopping, and
laundry to others. In the workplace, try
to arrange your environment to conserve
your energy, and plan your most strenuous
tasks during times of peak energy.
Talking with your employer and coworkers
about cancer-related fatigue can
help them understand this symptom.
Good Sleep Hygiene
Some simple
measures can be taken to help you sleep
at night. During the day, try to limit
naps. If you do nap, try not to sleep
for longer than 30 minutes. In the late
afternoon and evening, avoid caffeine,
chocolate, and alcohol. Also, limit liquid
intake in the evening. Try to go to
bed and wake up at the same time every
day, including weekends. Spouses
should try to go to bed at the same time
as well. Use your bedroom for sleep
and intimacy only. If you cannot fall
asleep within 15 minutes, then it is
fine to get up, go to another room, try
listening to quiet music, and then go
back to bed when you feel sleepy.
Exercise and Nutrition
Although
it might seem difficult, it is important to
remain active. Cancer survivors should
try to exercise on a daily basis if possible.
Before beginning an exercise
regimen, you should discuss an appropriate
program with a healthcare
professional. In some cases, it might
be advisable to be assessed by a physical
therapist. The eventual goal would
be to obtain 30 minutes of exercise per
day if possible.
Occasionally, you may also experience mental fatigue. If this is the case, try working crossword puzzles or engaging in other activities where you are required to focus your concentration. Finally, it is important to eat a well balanced diet that includes foods containing protein, such as meat, eggs, milk, and legumes. You should also remain well hydrated by drinking eight 8-ounce glasses of non-alcoholic, noncaffeinated fluids each day.
Restorative Therapy
It is beneficial
to engage in activities that you enjoy
and that help you feel relaxed. Try to
set aside time at least three times a week
for an activity that you enjoy, such as
listening to music, gardening, walking
through a park, bird watching, or visiting
with friends and family. You might
also want to try relaxation exercises.
These activities can be both mentally
and physically restorative.
Although cancer-related fatigue is the most common and distressing symptom in cancer survivors, there are many measures that can be taken to help manage this symptom. If the fatigue persists and significantly interferes with your daily life, you should discuss this symptom with a healthcare professional.
