Causes of Fibromyalgia
The exact cause of Fibromyalgia is still not known, but medical experts associate it with a number of factors such as:
Abnormal pain impulses (or messages):
The central nervous system comprises the brain, spinal cord, and nerves, and is responsible for the transmission of impulses, or signals of information, to all other parts of the body. Any alteration to the way this system works can explain why Fibromyalgia results in constant extreme feeling of and sensitivity to pain. For example, an increase in substance P (the chemical which increases nerve sensitivity to pain) in the cerebrospinal fluid (CSF) of the spinal cord may result in the wrong pain messages being sent to the brain.
Hormonal imbalance in the brain:
Research has found that Fibromyalgia patients have very low hormones noradrenaline, tryptophan, serotonin, and dopamine in the hypothalamic-pituitary-adrenal axis. This greatly affects how patients respond and cope with stress and pain.
Lack of deep sleep:
It is normally during stage 4 sleep that your muscles recover from the day’s activities. It is also at this time that the body refreshes itself. Getting poor quality sleep, or lighter forms of sleep, or failure to enter stage 4 sleep, is enough to make you develop symptoms of Fibromyalgia.
Some scientists think that a gene or genes might also be involved in Fibromyalgia. These genes are said to make you react strongly to things that other people wouldn’t find painful. If this is the case, a genetic predisposition (tendency) could, therefore, explain why a good number of people develop the condition after some sort of trigger.
Other possible causes of Fibromyalgia include: stressful or traumatic events, such as auto accident, illness, repetitive injuries, certain diseases and associated conditions such as osteoarthritis, lupus, rheumatoid arthritis, and ankylosing spondylitis.
