Chronic fatigue syndrome
One of the most controversial illnesses is the condition commonly known as Chronic Fatigue Syndrome (CFS). As the name suggests, people with this disease feel very tired and exhausted most of the time. Sometimes they may feel perfectly all right when resting, but find that even the smallest amount of exertion or light physical activity makes them quickly exhausted.
As well as this extreme tiredness, a number of other symptoms may be present in CFS. These include having a slightly raised temperature, sore throat, headaches and, quite often, tender aching muscles. The last symptom is the reason for the other name by which CFS is sometimes known — myalgic encephalomyelitis, or ME. Psychological problems such as anxiety and depression may also be seen.
The symptoms of CFS are very variable and can be due to a number of other things. There is no special test to confirm the diagnosis, which is one of the reasons that not everyone thinks that it is a 'real' illness. Usually tests are done to exclude other conditions, such as abnormalities of the thyroid gland, which can produce a similar picture. CFS is not usually diagnosed until the sufferer has been unwell for at least 6 months.
The cause of CFS is not known. It seems to often follow a 'flu-like' illness. Other viruses, such as the one responsible for glandular fever, have been suspected as a possible cause.
There is no specific treatment for CFS. Sometimes it just disappears, but it may last for a long time. Those with it have to adjust their lives and avoid long periods of activity. They will need lots of support and encouragement, particularly in view of the widespread controversy about the disease and its existence.
