Did you have a gynecologic surgery, such as a hysterectomy, in the few years before you developed fibromyalgia?
It’s a trend some people have noticed, and a study published in 2015 shores up the link between these types of surgeries and fibromyalgia onset. It also provides further evidence for an association between fibromyalgia and common overlapping conditions that are gynecologic, endocrine, or autoimmune.
Findings
In the study, researchers reviewed charts of 219 women with fibromyalgia and 116 women with non-fibromyalgia chronic pain. Specifically, they examined the time between illness onset and gynecologic surgery as well as the number of overlapping conditions in each group.
They also found that each of the three diagnosis types they were looking at was independently associated with fibromyalgia. Thyroid disease and gynecologic surgery were significantly more common in women with fibromyalgia than those with other types of chronic pain.
The timing of the gynecologic surgeries in relation to pain onset was especially interesting. They found more surgeries in the years just before fibromyalgia pain began, or in the year after pain onset. That pattern was unique to the fibromyalgia group.
At first glance, it may seem odd that gynecologic surgeries in the year after pain onset would be considered related to the development of fibromyalgia.
However, an association like that may be due to several pertinent factors.
For example, consider that many women have gynecologic problems well before they opt for surgery as the preferred treatment. It may be that hormonal changes or gynecologic disease are risk factors for fibromyalgia because of some underlying relationship that we don’t yet understand.
According to the study, hysterectomies and oophorectomies (removal of the ovaries) were most likely within the four years before or after the onset of fibromyalgia pain.
This is certainly an area that calls for more research. In the end, it could help us understand why 90 percent of fibromyalgia patients are women. Beyond that, it may reveal physiological changes that can trigger the development of the illness, which could lead to better treatments and possibly even prevention.
For the women who develop fibromyalgia after gynecologic surgery, we also need to know what role, if any, the surgery itself plays, as well as the possible roles of hormonal changes caused by the surgery. Post-surgical hormone replacement therapy deserves a look, too.
Earlier Research
Doctors have long suspected that fibromyalgia has strong hormonal ties and triggers. A 2013 studyfound links between early menopause and increased pain sensitivity in fibromyalgia patients, which may relate to dropping estrogen levels.
