Fibromyalgia Causes

The cause of Fibromyalgia is unknown. Physical or emotional trauma may play a role in development of the syndrome. A number of lines of evidence suggest that fibromyalgia patients have abnormal pain transmission responses.

It has been suggested that sleep disturbances, which are common in fibromyalgia patients, may actually cause the condition. Another hypothesis suggests that the disorder may be associated with changes in skeletal muscle metabolism, possibly caused by decreased blood flow, which could cause chronic fatigue and weakness.
 
 

The causes of fibromyalgia are unknown. There may be a number of factors involved. Fibromyalgia has been linked to:

  • Stressful or traumatic events, such as car accidents
  • Repetitive injuries
  • Illness
  • Certain diseases.

Others have suggested that an infectious microbe, such as a virus, triggers the illness. At this point, no such virus or microbe has been identified.

Pilot studies have shown a possible inherited tendency toward the disease, though evidence is very preliminary.

The disorder has an increased frequency among women 20 to 50 years old. The prevalence of the disease has been estimated between 0.7% and 13% for women, and between 0.2% and 3.9% for men.

Genetics as a cause for fibromyalgia

Some scientists speculate that a person’s genes may regulate the way his or her body processes painful stimuli. According to this theory, people with fibromyalgia may have a gene or genes that cause them to react strongly to stimuli that most people would not perceive as painful. There have already been several genes identified that occur more commonly in fibromyalgia patients, and NIAMS-supported researchers are currently looking at other possibilities.
