What causes the medical condition, fibromyalgia syndrome is still very much unknown to those within the medical community, but many medical experts are still researching the relationship between the female condition menopause and fibromyalgia.

Most women suffering from FM are diagnosed with this medical disorder between the ages of 40 to 55. This is usually when menopause frequently occurs, and approximately 85%-90% of all the reported fibromyalgia symptoms to doctors are women. Furthermore, hormonal changes, such as decreased estrogen levels in the female body, may also play a role in the developement of FMS symptoms like anxiety, depression, and wakefulness.

Medical research also shows, however, that estrogen and progesterone replacement therapy is not that beneficial to fibromyalgia sufferers. There are mild benefits reported when using the estrogen patches rather than the estrogen pills. Some studies also indicate that the low thyroid function and decreased levels of thyroid hormones, as well as estrogen and progesterone hormones, may also contribute to chronic muscular pain, fatigue, mood changes, depression and anxiety. At the present time the correlation between menopause and fibromyalgia is uncertain, due to the lack of research on the subject.

Fortunately, more tests are being conducted to find out how the declining estrogen levels affect the attack of fibromyalgia. Continuing research is being conducted that may suggest really low levels of the hormone Cortisol, which is the hormone produced by the adrenal gland, may also contribute to the cause of fibromyalgia syndrome.
