Gulf War Illness — also called Chronic Multisymptom Illness or Undiagnosed Illness — is a group of unexplained chronic health problems that many veterans developed after serving in the Gulf War region. The VA automatically covers it for qualifying veterans, meaning you don't need to prove your service caused it — you just need to show you have the symptoms and served in the right locations.
**Who qualifies:** Veterans who served in the Southwest Asia theater from August 2, 1990 to the present — including Operations Desert Shield, Desert Storm, Iraqi Freedom, and New Dawn — and veterans who served in Afghanistan, Syria, Djibouti, and several other locations. Your symptoms must have appeared during service or before December 31, 2026, and must have lasted (or be expected to last) at least six months.
**Common Gulf War Illness symptoms:** Fatigue that doesn't go away, joint and muscle pain, headaches, sleep problems, memory and concentration trouble, stomach and digestive issues, skin rashes, and breathing problems. You may have some but not all of these.
**Why "undiagnosed" matters:** Gulf War Illness is unique because it covers conditions that don't have a clear medical explanation — and the VA accepts that as a recognized condition rather than requiring a specific diagnosis. If doctors can't identify the exact cause of your symptoms, that doesn't disqualify you.
**Filing your claim:** Report all your symptoms in detail on your VA claim. A VSO can help you document them correctly. The more thorough the symptom picture, the more accurately the VA can rate your condition.
In real life
- A Desert Storm veteran with chronic joint pain and fatigue files a claim and is presumed service-connected.
- An Iraq War veteran with chronic GI issues qualifies under undiagnosed illness rules.
- A Gulf War veteran with chronic asthma and sinusitis files under PACT Act airborne hazard presumptives.
