Chronic Fatigue Syndrome (CFS)


This debilitating disorder causes severe exhaustion that doesn't go away after you rest. It makes even the most ordinary daily activities difficult to do.


We don't know how or why CFS develops. Scientists are studying possible links to certain viral infections. They are also looking at immune system problems and hormone imbalances. CFS can affect anyone, but it's mostly seen in women in their 40s and 50s. The syndrome is four times more common in women than in men.


CFS is often misdiagnosed. That's because many other diseases have the same symptoms. The main symptom of CFS is a heavy fatigue that lasts six months or more.

Other Symptoms

You will also have at least four of these other symptoms. You may have unsatisfying sleep. Physical activity may leave you feeling bad for more than a day. You may have poor memory or severe headaches. You may have sore muscles, and pain in multiple joints. You may also have a sore throat or tender lymph nodes.


There is no cure for CFS. Treatment depends on your symptoms. Treatment includes medications, modified sleep routines, stretching and massage therapy.
