How is chronic fatigue syndrome diagnosed?

CFS is complicated and difficult to diagnose. Some people have a hard time accepting CFS as a disease. It's important to remember that your fatigue is real and that you can work with your doctor to improve your symptoms.

The first step is to see if there is any other explainable cause for your fatigue. Your doctor will probably want to review your symptoms and medical history, and give you a physical exam. Your doctor may also want to do some blood tests, but lab testing is not often helpful in the diagnosis of CFS.
