Functional Gastrointestinal Disorders (IBS, Functional Dyspepsia)
About This Condition
Chronic disorders of the gastrointestinal tract — including irritable bowel syndrome (IBS), functional dyspepsia, and related conditions — characterized by recurring symptoms without a structural or biochemical cause. These conditions are extremely common among Gulf War and post-9/11 veterans and are recognized as Gulf War presumptive conditions, meaning VA presumes service connection without requiring proof of a specific cause.
Evidence Needed
- Gastroenterologist evaluation confirming functional GI disorder
- Colonoscopy/endoscopy ruling out structural causes
- Documentation of symptom pattern and frequency
- Documentation of qualifying Gulf War or post-9/11 service
