- Age. CFS affects people in their 40s and 50s, but people of any age can get it

- Mood swings
- Low-grade fever
The symptoms of CFS may look like other medical conditions. Always consult your health care provider for a diagnosis.
How is chronic fatigue syndrome diagnosed?
CFS diagnosis depends on two criteria:
- Severity and duration. The severe and chronic tiredness lasts for more than 6 months and other medical conditions have been ruled out.
- Number of symptoms. Four or more symptoms of CFS are present.
A specific treatment for CFS has yet to be proven effective. Vitamin supplements and medications have some benefit. Many treatments just relieve the symptoms of CFS.
