Chronic fatigue
syndrome (CFS) is a complicated disorder
characterized by profound
fatigue that doesn't improve
with bed rest and may
worsen with physical or mental
activity.
Of all chronic illnesses,
CFS is one of the most mysterious. Unlike
infections, it has no clear
cause.
Unlike
conditions such as diabetes or anemia,
there's
essentially nothing to
measure.
And unlike conditions
such as heart disease,
there are relatively few treatment
options.
CFS may occur
after an infection such as a cold, bronchitis,
mononucleosis, hepatitis
or intestinal illness.
It can start
during or shortly after a period
of high stress or come on
gradually without any clear starting
point and any
obvious
cause.
CFS is a flu-like condition
that can drain your energy and sometimes
last for years.
People
previously
healthy and full of energy may experience
extreme fatigue,
weakness and headaches
as well as painful joints, muscles and
lymph nodes.
Women are diagnosed
with CFS two to four times as often as men are.
However, it's unclear
whether CFS affects women
more frequently or if women report it to their doctors
more often than men do.
An estimated
500,000 people in the United States have a CFS-like condition.
CFS can affect a person of any age or
race.
Signs and symptoms
CFS exhibits
signs and symptoms similar to those
of most common viral infections.
Unlike
flu (influenza) symptoms, which usually subside in a
few days or weeks, the signs and symptoms of
CFS can last for months or years.
They may come and go frequently with no
identifiable pattern.
In addition
to persistent fatigue not caused by
other known medical conditions, CFS
has eight possible
primary symptoms.
These include:
-
Loss of
memory or concentration
-
Sore
throat
-
Painful
and mildly enlarged lymph nodes in your neck or
armpits (axillae)
-
Unexplained
muscle soreness
-
Pain
that moves from one joint to another without swelling
or redness
-
Headache of a new type, pattern or severity
-
Sleep
disturbance
-
Extreme
exhaustion after normal exercise or exertion
Chronic Fatigue
Syndrome Study Group is a group of scientists, researchers
and doctors brought together by the Centers for Disease Control
and Prevention (CDC) to determine a
standard method for defining and diagnosing
CFS
According
to the International Chronic Fatigue
Syndrome Study Group a person meets the diagnostic criteria of CFS when unexplained persistent fatigue
occurs for six months or more, with at least four of the eight
primary symptoms also
present.
In addition,
people with CFS have reported other various signs and
symptoms that aren't part of the official
definition of CFS determined by the
International Chronic Fatigue
Study Group.
These include:
People with CFS
usually experience the most severe
symptoms within the first one to two months of
illness.
After that, a small number of those affected
recover completely
while a small percentage of others become incapacitated
by their symptoms.
However,
for most people a gradual improvement occurs,
although those affected
by CFS often don't regain their normal level of
energy.
Risk factors
Women are diagnosed
with CFS two to four times as often as men are, but sex isn't a proven risk factor
for the condition.
Because the cause of
CFS is unknown, doctors have yet to
determine and confirm definite risk
factors for the disease.
