The constant fatigue syndrome is also called as the fibromyalgia or the FMS disorder which is not a very serious and life threatening disease. The disorder affects the muscles and bones and joints of the individual causing pain and fatigue all over his/her body. The patient with the FMS condition is not at all fresh; he feels stressed out and exhausted even after his/her sleep. The disorder affects in a very peculiar way, the patient has on the particular parts of his body such tender and sensitive places that experience pain as soon as they are pressurized slightly. The diagnostic criteria for this disease has been devised by the American College of Rheumatology and which has laid down certain points for the diagnosis of the disease which are known as the ACR1990. The disease doesn't have any cure and is also not at all life threatening. There are many risk factors for this disease from which one can see for himself if he/she is prone to FMS.

Factors:

The risk factors like gender, age are the most important factors in the FMS disease. It has been claimed that the sex of the patient determines the risk of the FMS and women are the most prone to the fibromyalgia disease than men. The ratio for this is 9:1 which confirms the fact. However men are also at the risk of the FMS and it can hit at any point of time. Among the FMS patients the percentage of women is 80% to 90% and the disease attacks them in their menopause stage. The reason behind this is not known yet. The age factor is also significant in the risk of FMS. Many of the fibromyalgia patients are in the age of 20 to 50 or even 60. Most women who develop fibromyalgia do so during their childbearing years and are middle aged. But it is not to say that elderly men and women cannot develop the FMS disorder.

The individual's genetic predisposition also determines the risk of fibromyalgia and in most of the cases it has been almost confirmed that women whose blood relative has had this FMS syndrome is most prone to the fibromyalgia disease. It seems that the FMS runs in the family of the patients. There are other factors like the sleep disorders of an individual greatly increases the chances of getting the FMS disease. If one has had an injury in accident and if one also lupus then the risk greatly increases for fibromyalgia.
