What Is Chronic Fatigue Syndrome?
Chronic Fatigue Syndrome (CFS) is a medical problem that causes many
people to become so fatigued and tired that they are not able to
adequately function or perform normal daily tasks. This is called
chronic fatigue. The main criteria for making the diagnosis of CFS are
chronic fatigue that causes at least a 50% reduction in activity and
ability to function, lasting for 6 or more months. Typical of CFS is
that physical or mental activity often makes the symptoms worse, and
rest usually doesn't improve symptoms.
CFS is unfortunately a complicated and difficult to diagnose. Some
people have a hard time accepting CFS as a disease. It's important to
remember that this fatigue is real and that they can work with their
doctor to improve their symptoms.
What Other Symptoms Occur With CFS?
Not only do people with CFS experience fatigue that lasts for long
periods of time, but they often experience a number of other symptoms
such as headaches, sore throat, tender or pain involving their neck or
armpits, unexplained muscle soreness, pain that moves from joint to
joint without swelling or redness, loss of memory or concentration,
trouble sleeping and extreme tiredness after exercising often lasting
more than 24 hours. These and other symptoms often either come and go or
won't go away. They often last for 6 months or more.
CFS may occur after an illness such as a cold or it can start during
or shortly after a period of high stress. It often comes on slowly
without any clear starting point or any obvious cause. In some cases,
CFS may last for years then suddenly go away.

What Causes Chronic Fatigue Syndrome?
We do not know what causes CFS. CFS may be caused by an immune system
that isn't working well, it may be caused by a yet unknown virus.
Researchers are still looking for the cause of CFS.
How Is Chronic Fatigue Syndrome Treated?
The first step is to see if there is any other explainable cause for
the fatigue. Your physician will likely want to review your symptoms and
medical history, and perform a comprehensive physical examination.
Diagnostic tests will generally be done to rule in or out conditions
which might be indicated by your symptoms, however, generally lab
testing is not very helpful when the diagnosis is CFS.
Some of the symptoms, such as muscle aches, sleep problems, anxiety
and depression, can be treated with medications. These medications
usually only help to relieve the symptoms and allow you to be more
active, they do not however, cure the fatigue. To date there is no
single medicine that cures the entire syndrome. Fortunately, most
symptoms improve with time.
What Can I Do To Help Myself?
- You can keep a daily diary to identify the times and conditions
when your energy returns. Plan your activities around these times.
- You can keep up some level of activity and exercise, within your
abilities. You can work with your doctor to help you plan an
exercise program to maintain your strength at whatever level is
possible. Exercise can help your body and mind. Becoming sedimentary
and allowing your muscles to atrophy will not help you at all.
- Give yourself all the permission you need to recognize and
express your feelings, especially any sadness, anger or frustration
you are experiencing. You may need to grieve for the energy you have
- Ask for support from your family and friends. Look for support
groups or counseling in your community. Ask your doctor for help in
finding resources. Emotional support is important for coping with a
chronic health problem.
- If your memory and concentration are affected by chronic
fatigue, keep lists and make notes to remind yourself of important
things. Also, give yourself more time for activities that take
concentration. Medicine may also help you sleep better, which might
improve your memory and concentration.
