Gulf War Veterans’ Medically Unexplained Illnesses
Read about presumptive conditions for Gulf War Veterans.
A prominent condition affecting Gulf War Veterans is a cluster of medically unexplained chronic symptoms that can include fatigue, headaches, joint pain, indigestion, insomnia, dizziness, respiratory disorders, and memory problems.
VA refers to these illnesses as "chronic multisymptom illness" and "undiagnosed illnesses." We prefer not to use the term “Gulf War Syndrome” when referring to medically unexplained symptoms reported by Gulf War Veterans. Why? Because symptoms vary widely.
Gulf War Veterans who meet the criteria below do not need to prove a connection between their military service and illnesses in order to receive VA disability compensation.
VA presumes certain chronic, unexplained symptoms existing for 6 months or more are related to Gulf War service without regard to cause. These "presumptive" illnesses must have appeared during active duty in the Southwest Asia theater of military operations or by December 31, 2026, and be at least 10 percent disabling. These illnesses include:
- Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), a condition of long-term and severe fatigue that is not relieved by rest and is not directly caused by other conditions.
- Fibromyalgia, a condition characterized by widespread muscle pain. Other symptoms may include insomnia, morning stiffness, headache, and memory problems.
- Functional gastrointestinal disorders, a group of conditions marked by chronic or recurrent symptoms related to any part of the gastrointestinal tract. Functional condition refers to an abnormal function of an organ, without a structural alteration in the tissues. Examples include irritable bowel syndrome (IBS), functional dyspepsia, and functional abdominal pain syndrome.
- Undiagnosed illnesses with symptoms that may include but are not limited to: abnormal weight loss, fatigue, cardiovascular disease, muscle and joint pain, headache, menstrual disorders, neurological and psychological problems, skin conditions, respiratory disorders, and sleep disturbances.
Gulf War Veterans may be eligible for a variety of VA benefits, including a Gulf War Registry health exam, the Airborne Hazards and Open Burn Pit Registry, health care, and disability compensation for diseases related to military service. Their dependents and survivors also may be eligible for benefits.
Gulf War Veterans are eligible for presumptive conditions due to exposure to airborne hazards. Find these conditions in the Health Care and Benefits section of the Airborne Hazards and Burn Pit Exposures web page.

Research on Gulf War Veterans' illnesses
VA and other researchers continue to conduct research to investigate how service in the Gulf War is linked to illnesses Gulf War Veterans have experienced. Research includes:
- Multiyear health survey of Gulf War-era Veterans to find out how their health has changed over time
- Studies by VA's War Related Illness and Injury Study Center
VA contracts with the Health and Medicine Division (HMD) (formally known as the Institute of Medicine) of the National Academy of Sciences, Engineering, and Medicine to scientifically review the evidence for possible connections between Gulf War Veterans' illnesses and exposure to environmental agents or preventive medicine during service, and the best treatments for these illnesses.
VA is currently reviewing HMD's latest Gulf War and Health report, Gulf War and Health: Volume 10: Update of Health Effects of Serving in the Gulf War, 2016.
