Chronic Fatigue Syndrome

Chronic fatigue syndrome is a complicated disorder characterized by extreme fatigue (tiredness) that can't be explained by any underlying medical condition. The fatigue may worsen with physical or mental activity, but doesn't improve with rest.
The cause of chronic fatigue syndrome is unknown, although there are many theories - ranging from viral infections to psychological stress. Some experts believe chronic fatigue syndrome might be triggered by a combination of factors.
Symptoms
Chronic fatigue syndrome has eight official signs and symptoms, plus the central symptom that gives the condition its name:
  • Fatigue
  • Loss of memory or concentration
  • Sore throat
  • Enlarged lymph nodes in your neck or armpits
  • Unexplained muscle pain
  • Pain that moves from one joint to another without swelling or redness
  • Headache of a new type, pattern or severity
  • Unrefreshing sleep
  • Extreme exhaustion lasting more than 24 hours after physical or mental exercise
Causes
Scientists don't know exactly what causes chronic fatigue syndrome. It may be a combination of factors that affect people who were born with a predisposition for the disorder.
Some of the factors that have been studied include:
  • Viral infections. Because some people develop chronic fatigue syndrome after having a viral infection, researchers question whether some viruses might trigger the disorder.Suspicious viruses include Epstein-Barr virus, human herpes virus 6 and mouse leukemia viruses. No conclusive link has yet been found.
  • Immune system problems. The immune systems of people who have chronic fatigue syndrome appear to be impaired slightly, but it's unclear if this impairment is enough to actually cause the disorder.
  • Hormonal imbalances. People who have chronic fatigue syndrome also sometimes experience abnormal blood levels of hormones produced in the hypothalamus, pituitary glands or adrenal glands. But the significance of these abnormalities is still unknown.
Risk factors
  • Age. Chronic fatigue syndrome can occur at any age, but it most commonly affects people in their 40s and 50s.
  • Sex. Women are diagnosed with chronic fatigue syndrome much more often than men, but it may be that women are simply more likely to report their symptoms to a doctor.
  • Stress.
Complications
Possible complications of chronic fatigue syndrome include:
  • Depression
  • Social isolation
  • Lifestyle restrictions
  • Increased work absence
Tests and diagnosis
There's no single test to confirm a diagnosis of chronic fatigue syndrome. Because the symptoms of chronic fatigue syndrome can mimic so many other health problems, you may need patience while waiting for a diagnosis.
To meet the diagnostic criteria of chronic fatigue syndrome, you must have unexplained, persistent fatigue for six months or more, along with at least four of the following signs and symptoms:
  • Loss of memory or concentration
  • Sore throat
  • Enlarged lymph nodes in your neck or armpits
  • Unexplained muscle pain
  • Pain that moves from one joint to another without swelling or redness
  • Headache of a new type, pattern or severity
  • Unrefreshing sleep
  • Extreme exhaustion lasting more than 24 hours after physical or mental excersice
Treatments and drugs
Treatment for chronic fatigue syndrome focuses on symptom relief.
  • Antidepressants. Many people who have chronic fatigue syndrome are also depressed. Treating your depression can make it easier for you to cope with the problems associated with chronic fatigue syndrome. Low doses of some antidepressants also can help improve sleep and relieve pain.
  • Sleeping pills. If home measures, such as avoiding caffeine, don't help you get better rest at night, your doctor might suggest trying prescription sleep aids.
Therapy

The most effective treatment for chronic fatigue syndrome appears to be a two-pronged approach that combines psychological counseling with a gentle exercise program.

Graded exercise. A physical therapist can help determine what types of exercise are best for you. Inactive people often begin with range-of-motion and stretching exercises for just a few minutes a day.
If you're exhausted the next day, you're doing too much. Your strength and endurance will improve as you gradually increase the intensity of your exercise over time.

Psychological counseling. Talking with a counselor can help you figure out options to work around some of the limitations that chronic fatigue syndrome imposes on you. Feeling more in control of your life can improve your outlook dramatically.al exercise

Lifestyle changes:-Reduce stress. Develop a plan to avoid or limit overexertion and emotional stress. Allow yourself time each day to relax. That may mean learning how to say no without guilt.

Improve sleep habits. Go to bed and get up at the same time each day. Limit daytime napping and avoid caffeine, alcohol and nicotine.

Pace yourself. Keep your activity on an even level. If you do too much on your good days, you may have more bad days.

Many alternative therapies have been promoted for chronic fatigue syndrome. It's difficult to determine whether these therapies actually work, partly because the symptoms of chronic fatigue syndrome often are linked to mood and can vary from day to day.

Pain associated with chronic fatigue syndrome may be helped by:
Acupuncture
Massage
Yoga or tai chi
Coping and support

The experience of chronic fatigue syndrome varies from person to person. For many people, however, the symptoms are more bothersome early in the course of the illness and then gradually decrease. Emotional support and counseling may help you and your loved ones deal with the uncertainties and restrictions of chronic fatigue syndrome.

You may find it therapeutic to join a support group and meet other people with chronic fatigue syndrome. Support groups aren't for everyone, and you may find that a support group adds to your stress rather than relieves it. Experiment and use your own judgment to determine what's best for you.
