What is Fibromyalgia?
Chronic widespread body pain is the primary symptom of Fibromyalgia (fi·bro·my·al·gi·a) . Most people with Fibromyalgia also experience moderate to extreme fatigue, sleep disturbances, sensitivity to touch, light, and sound, and cognitive difficulties. Many individuals also experience a number of other symptoms and overlapping conditions, such as irritable bowel syndrome, Migraines, and Interstitial Cystitis.
Symptoms often begin after an event, such as physical trauma, surgery, infection or significant psychological stress. In other cases, symptoms gradually accumulate over time with no single triggering event.
Fibromyalgia (pronounced fy-bro-my-AL-ja) is a complex chronic pain disorder that affects an estimated 5 to 8 million Americans. While it occurs most often in women, it can occur in men and children, and all ethnic backgrounds. For those with severe symptoms, fibromyalgia (FM) can be extremely debilitating and interfere with basic daily activities.
- The FM classification criteria, established by the American College of Rheumatology (ACR) in 1990, includes a history of widespread pain in all four quadrants of the body for a minimum duration of three months, and pain in at least 11 of the 18 designated tender points when a specified amount of pressure is applied.
- New diagnostic criteria were developed by the American College of Rheumatology (ACR) in 2010. These criteria do not use tender points but focus upon pain being widespread and accompanied by allied symptoms such as sleep problems, problems with thinking clearly, and fatigue.
- Since people with FM tend to look healthy and conventional tests are typically normal, a physician knowledgeable about the disorder is necessary to make a diagnosis.
- Physicians should rule out other causes of the symptoms before making a diagnosis of fibromyalgia.
The underlying cause or causes of FM is closer to being understood because of new research findings that continue to bring a better understanding of the basic mechanisms of fibromyalgia. Most researchers agree that FM is a disorder of central processing with neuroendocrine/neurotransmitter dysregulation.
The FM patient experiences pain amplification due to abnormal sensory processing in the central nervous system. An increasing number of scientific studies now show multiple physiological abnormalities in the FM patient, including: increased levels of substance P in the spinal cord, low levels of blood flow to the thalamus region of the brain, HPA axis hypofunction, low levels of serotonin and tryptophan and abnormalities in cytokine function.
Recent studies show that genetic factors may predispose individuals to a genetic susceptibility to FM. For some, the onset of FM is slow; however, in a large percentage of patients the onset is triggered by an illness or injury that causes trauma to the body. These events may act to incite an undetected physiological problem already present.
Exciting new research has also begun in the areas of brain imaging. Ongoing research will test the hypothesis that FM is caused by an interpretative defect in the central nervous system that brings about abnormal pain perception. Medical researchers have just begun to untangle the truths about this life-altering disease.
One of the most important factors in improving the symptoms of Fibro is for the patient to recognize the need for lifestyle adaptation. Most people are resistant to change because it implies adjustment, discomfort and effort. However, in the case of FM, change can bring about recognizable improvement in function and quality of life. Becoming educated about Fibro gives the patient more potential for improvement.
An empathetic physician who is knowledgeable about the diagnosis and treatment of Fibromyalgia and who will listen to and work with the patient is an important component of treatment. It may be a family practitioner, an internist, or a specialist (rheumatologist or neurologist, for example).
Conventional medical intervention may be only part of a potential treatment program. Alternative treatments, nutrition, relaxation techniques, and exercise play an important role in FM treatment as well. Each patient should, with the input of a healthcare practitioner, establish a multifaceted and individualized approach that works for them.
