Chronic Fatigue Syndrome / Myalgic Encephalomyelitis (CFS/ME) is a condition of long-term disabling tiredness (fatigue). The cause is not known, but a popular theory is that a virus infection may trigger the condition.

People diagnosed with CFS/ME have some common complaints and symptoms including fatigue, insomnia, nausea, headaches, inability to concentrate, joint pain and muscle aches. CFS/ME can affect anyone, making their everyday life very difficult. Although it is much less common in children than in adults, children can develop the illness, particularly during their teen years.

CFS may last for years. However, most people do recover, or at least adjust their lifestyle to improve their symptoms. Great Ormond Street Hospital has an effective rehabilitation programme to help young people cope with the condition. The CFS/ME team is made up of a nurse consultant, social worker, physiotherapist, doctor and secretary. They also encourage the involvement of family, school teachers and health teams. Each person plays a different part in helping sufferers become better and more able to manage the symptoms of CFS/ME.
