What is Chronic Fatigue Syndrome?
Chronic fatigue syndrome is a complex disorder characterized by extreme fatigue that cannot be explained by any underlying medical condition. The fatigue may worsen with physical or mental activity, but does not 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 the disorder might be triggered by a combination of factors. There is no single test to confirm a diagnosis of chronic fatigue syndrome. You may need a variety of medical tests to rule out other health problems that have similar symptoms. Treatment for the disorder focuses on symptom relief. Symptoms affect several body systems and may include weakness, muscle pain, impaired memory and/or mental concentration, and insomnia, which can result in reduced participation in daily activities.
