What causes chronic fatigue syndrome?
The cause of CFS isn’t known. It may be from a viral infection in some people. But the exact cause is almost always unclear. Other possible causes being studied are genetics and immune system problems.

Gender. CFS happens up to 2 to 4 times more often in women than in men.
Age. CFS often affects middle-aged people. But people of any age can get it.

Fatigue and weakness
Muscle and joint pain
Inability to focus
Feelings of exhaustion after putting out physical or mental energy
Many of these symptoms may be caused by other health problems. Always talk with your healthcare provider for a diagnosis.
How is chronic fatigue syndrome diagnosed?
A CFS diagnosis must rule out other possible conditions. According to the Institute of Medicine, a CFS diagnosis requires all 3 of these symptoms:
Having to cut back greatly on activities you did before the illness. Severe and chronic tiredness must have lasted for more than 6 months, and other health conditions have been ruled out. Rest does not ease these symptoms.
Severe tiredness after physical activity. The fatigue gets worsen after physical or mental stress that you could handle before the illness started.
Sleep that doesn’t refresh you.
In addition, you must have 1 of these symptoms:
Trouble thinking that gets worse under pressure.
Orthostatic intolerance. This means standing upright makes symptoms worse. Lying back down or raising (elevating) your feet may ease the symptoms. But it doesn’t fully get rid of them.
How is chronic fatigue syndrome treated?
There is no cure for CFS. Treatment is aimed at easing symptoms.
Treatment may include:
Medicine, including corticosteroids and antidepressants
Activity management, including a careful balancing of rest and activity to prevent flare-ups
Light-intensity aerobic exercise, but not moderate to vigorously intense physical activity
Dietary supplements and herbal products
Psychotherapy and supportive counseling
