The condition now called "Gulf War Illness" has been studied extensively,(1)(2) however, there remains great debate about its potential causes or whether it exists as a distinct condition.
About 700,000 men and women served in the first Gulf War (Operation Desert Shield, Operation Desert Storm). Nearly a quarter million of those returning were reported to have experienced or continue to experience symptoms and illnesses which led to an investigation as to whether or not they were caused by a specific toxic/hazardous/biological exposures which occurred during these operations.source
Some known and documented symptoms reported by those returning from the area, as well as those who are native to the region:
The signs and symptoms reported by sufferers are similar to Fibromyalgia and Chronic Fatigue Syndrome. All of these are ill-defined clinical entities which consist mainly of non-specific symptoms any of which could have a wide variety of causes. This makes definitive diagnosis of a specific Gulf War Illness very difficult. As it stands now, no single entity has been singled out as the cause:
“It is likely that multisymptom illness results from the interactions between environmental exposures and genes, and genetics may predispose some individuals to illness,” - Institute of Medicine Apr. 2010 report to Department of Veteran's Affairs
Some known and documented exposures (according to the US Dept. of Veteran's Affairs)considered as potential causes for these symptoms were:
- Burn pits
- Chemical and biological warfare agents
- Depleted Uranium
- Oil fires
- Pesticides
- Phyridostigmine Bromide
- Vaccinations
Some have suggested psychological or psychogenic causes for the symptoms (which are no less legitimate medically). However, this is one of the theories that is most widely refuted, arguing that the evidence indicates a physical cause.
The Veteran's Administration assumes that certain illnesses (even if unexplained) are related to qualifying military service. These are called “presumptive illnesses." These include:
- medically inexplained chronic multisymptom illnesses
- Infectious disease
- ALS diagnosed in veterans with 90 days of consecutive service.
However, this isn't proof that Gulf War Illness exists as a distinct clinical entity, it is acknowledged and treated under the presumption that it does exist.
Conspiracy?
There are also many sources who cite theories of denial or cover-up by various governments or organizations.
Estimates place the number of sick soldiers for more than 150,000 and about 10,000 being dead already because of the syndrome. (Estimates may be optimistic). A study of the Gulf War Syndrome clearly shows it to be a virus that is not natural, but that has all the features of one created in the lab. One of the main suspects for the syndrome is an artificial agent called Microplasma fermentans (unknown origins). It contains most of the HIV genes, suspected to have been added through laboratory amendments. Of all the countries involved in Gulf War coalition, only France refused the inoculation. Until recently, there weren’t any reported cases of the syndrome among French soldiers. source
However, some claim non-cooperation from the government mainly inspired a lack of trust in official information, which added a level of complexity to finding the cause. They do not suggest outright conspiracy.
The first example of Pentagon non-cooperation that exacerbated suffering for veterans and their families was the constant denials, until 1996, of any health risks from widespread exposure to low levels of chemical agents. source
Many theories attempt to explain Gulf War Illness...
- Is this a case of common symptoms originating from a wide variety of causes being grouped together after the fact, rather than one specific illness?
- Is there evidence that Gulf War Illness does have a known cause that is being covered up by a conspiracy?
- Although many potential causes have been considered, has any one specific cause or agent been shown to be more likely than the others?
I know that this question is phrased mainly with regard to American personnel, but this is only because most of the information I found had to do with the US military. Answers can obviously include relevant information from other countries.
