Gulf War Syndrome and Fibromyalgia. What's The Connection

By Adrienne Dellwo | Reviewed by Grant Hughes, MD
The Persian Gulf War began in 1991, but more than 170,000 veterans still are battling Gulf War syndrome. For 17 years, they battled stigma and disbelief, but finally, in late 2008 a congressionally mandated panel concluded that Gulf War syndrome (GWS) is in fact “real” and is not a psychological condition.
Veterans with GWS also are more prone to fibromyalgia (FMS) and chronic fatigue syndrome (CFS or ME/CFS), as well as to a few other conditions.
What Is Gulf War Syndrome?
GWS is a debilitating, multi-symptom illness that, according to researchers, was caused by exposure to toxic chemicals. Many of those chemicals were intended to protect military personnel, such as pesticides against sand flies and other pests and a drug to protect them against nerve gas. Very few of those who developed GWS have gotten better.
For years, GWS was generally considered a result of the stress of combat. However, researchers have discovered that the veterans who developed the condition are more likely to have a genetic mutation that made them less able to tolerate certain chemicals and toxins compared with those who did not develop GWS. The same mutation is linked to some neurological diseases, including ALS (amyotrophic lateral sclerosis, aka Lou Gehrig’s disease). ALS and brain cancer also are more common in people with GWS than in the general population.
Gulf War Syndrome in Fibromyalgia & ME/CFS
The jury is still out on why GWS apparently predisposes people to FMS and ME/CFS. The conditions all have similar symptoms and include neurological involvement.
All three conditions are linked to migraines (as an overlapping condition.) FMS, ME/CFS, and migraine are all considered to be central sensitivity syndromes, meaning that they involve hyper-sensitivity of the central nervous system.
A 2012 study revealed abnormal pain processing in many cases of GWS, especially when it came to exposure to heat. FMS is known to involve a similar reaction to temperature. This could mean the conditions have a common underlying mechanism.
So is GWS a central sensitivity condition? We can’t answer that question yet, but evidence suggests that it could be, or that it’s somehow related to that class of illnesses.
Although we now know an important cause of GWS, the underlying processes involved still aren’t clear. It’s likely that we’ll have to learn more about all these conditions before we truly understand their relationship to each other.
Diagnosing GWS is similar to diagnosing FMS and ME/CFS: self-reported symptoms and tests to exclude other possible causes of those symptoms.
Symptoms of Gulf War Syndrome
Symptoms of Gulf War syndrome include:
Chronic fatigue
Cognitive dysfunction
Joint and muscle pain
Pain or discomfort related to sexual intercourse
Of those symptoms, bronchitis, asthma, and pain related to intercourse are the only ones not shared by FMS and ME/CFS.
GWS also is associated with post-traumatic stress disorder and alcohol abuse.
Treating Gulf War Syndrome
So far, there’s no specific treatment regimen for GWS.
Current treatments focus on symptom relief, i.e. drugs for depression and pain, as well as psychological counseling for problems such as depression, anxiety, post-traumatic stress disorder, and alcoholism.
Some veterans report finding relief from complementary/alternative therapies, including acupuncture, nutrition, supplements, and hypnotherapy.
Gulf War Syndrome Treatment vs. FMS & ME/CFS Treatment
Because treatment for all three of these conditions focuses on symptom relief and the symptoms are all so similar, it’s unlikely that treatment for GWS would conflict or interfere with treatment for FMS or ME/CFS.
Any time you’re being treated for more than one condition, however, it’s important to talk to your doctor and pharmacist about possible drug interactions and to make sure all of your health-care providers are informed about your treatment and management regimen.
Living With GWS
Veterans with GWS are eligible for benefits from the Veterans Administration, which can help provide access to proper healthcare and cover the cost. Learn more about VA assistance:
The fact that GWS is now officially recognized as a physiological illness should help remove the social stigma and end disbelief in the medical community, which can be psychologically damaging.
The congressional panel on GWS recommended 60-million dollars in annual funding for GWS research. If research is funded at that level, it could provide better treatments in the future. Finally, the outlook for veterans with GWS appears to be improving.
