Chronic fatigue syndrome (CFS) is a debilitating and often misunderstood condition. It is a complex disorder that can affect people of all ages, but is most common in adults over the age of 40. CFS is characterized by extreme fatigue that is not relieved by rest, even after adequate sleep. It can also cause significant problems with concentration, memory, and productivity.

There is no one cause of CFS, but it is believed to be caused by a combination of environmental and genetic factors. Many people with CFS also have a history of viral or bacterial infections, which may have contributed to the development of the condition. There is currently no cure for CFS, but there are treatments that can help improve the symptoms.

If you are experiencing symptoms of CFS, it is important to talk to your doctor. He or she can help you determine if you have the condition and recommend the best treatment options.
