The DBQ for IBS (Irritable Bowel Syndrome)
Your C&P examiner fills out DBQ 21-0960G-3 (Intestinal Conditions (Other Than Surgical or Infectious)) — the form that decides your rating. You can have your own doctor complete the same DBQ and submit it as evidence.
What the examiner measures
- Frequency and severity of diarrhea, constipation, or alternating diarrhea and constipation
- Abdominal distress and whether it is occasional, frequent, or more or less constant
- Number/frequency of symptom exacerbations over the past 12 months
- Whether findings support mild, moderate, or severe irritable colon (DC 7319); weight loss or other objective signs

Rating Criteria for IBS (Irritable Bowel Syndrome)
Rating schedule under 38 CFR 4.114, DC 7319 (irritable bowel syndrome, revised 2024). Criteria are simplified summaries; your specific rating depends on severity documented in your C&P exam.
Abdominal pain related to defecation at least once during the previous three months, plus two or more of: change in stool frequency, change in stool form, altered stool passage (straining/urgency), mucorrhea, abdominal bloating, or subjective distension.
Abdominal pain related to defecation for at least three days per month during the previous three months, plus two or more of the above symptoms.
Abdominal pain related to defecation at least one day per week during the previous three months, plus two or more of the above symptoms.
Verified against 38 CFR Part 4, the official VA rating schedule. Reviewed July 2026.

Peer-Reviewed Medical Evidence
Real, verified studies from PubMed/NIH that support a IBS (Irritable Bowel Syndrome) claim. Bring these citations to your accredited VSO or C&P exam — they help show your condition is recognized in the medical literature and, where noted, linked to other service-connected conditions.
Military Medicine, 2024 · PMID 38771213
Finding: Among 578 deployed Gulf War veterans evaluated at VA's WRIISC, current IBS (Rome IV) affected 42.2% and physician-diagnosed IBS history 50.3%. Severe Gulf War illness was significantly associated with current IBS (adjusted OR 1.68, 95% CI 1.11-2.54) and with history of physician-diagnosed IBS (aOR 2.15, 95% CI 1.43-2.23).
Why it helps: Directly supports an association between Gulf War deployment/Gulf War illness and IBS in veterans, with VA-specific prevalence figures and adjusted odds ratios useful for framing a service-connection or secondary-to-GWI claim.
Digestive Diseases and Sciences, 2011 · PMID 21643738
Finding: In a matched case-control study of active-duty service members using Defense Medical Surveillance System data, self-reported diarrhea and/or vomiting during deployment was significantly associated with later development of functional GI disorders including IBS (129 FGD cases, 22 IBS).
Why it helps: Supports an association between deployment-acquired infectious gastroenteritis (travelers' diarrhea) and later IBS in military personnel, a core mechanism for a direct service-connection claim.
Journal of Neurogastroenterology and Motility, 2012 · PMID 22523730
Finding: Modeling the contribution of acute gastroenteritis to IBS prevalence, the authors found that under a high one-year exposure scenario such as military deployment, the maximum (steady-state) IBS prevalence was reached in under one year, indicating substantially elevated risk in deployed populations.
Why it helps: Supports the inference that the high gastroenteritis exposure of a deployment is a meaningful driver of post-infectious IBS, reinforcing a direct deployment-to-IBS nexus.
Gastroenterology, 2017 · PMID 28069350
Finding: Meta-analysis of 45 studies (21,421 individuals) found pooled IBS prevalence of 10.1% within 12 months and 14.5% beyond 12 months after infectious enteritis; risk of IBS was 4.2-fold higher within 12 months (95% CI 3.1-5.7) than in those without enteritis, with higher risk in women and those with antibiotic exposure, anxiety, and depression.
Why it helps: Establishes the post-infectious IBS link with strong pooled numbers; supports an association between an in-service episode of infectious gastroenteritis (common on deployment) and subsequent IBS.
Scandinavian Journal of Gastroenterology, 2019 · PMID 31112663
Finding: Meta-analysis of 34 studies found pooled IBS prevalence of roughly 11-14% after bacterial gastroenteritis (Campylobacter, Salmonella, Shigella, C. difficile, E. coli); overall odds of IBS after any-pathogen acute gastroenteritis were 4.9-fold higher (95% CI 3.9-6.1), and after bacterial gastroenteritis 5.8-fold (95% CI 4.0-8.3).
Why it helps: Corroborates that documented in-service bacterial gastroenteritis substantially raises later IBS odds, supporting a post-infectious direct nexus regardless of the specific organism.
Journal of Gastroenterology and Hepatology, 2019 · nexus to PTSD (post-traumatic stress disorder) · PMID 30144372
Finding: Meta-analysis of 8 studies (648,375 subjects, most from the USA and conducted on army veterans) found PTSD to be a significant risk factor for IBS, with a pooled odds ratio of 2.80 (95% CI 2.06-3.54, P < 0.001).
Why it helps: Supports an association between service-connected PTSD and IBS, directly useful for an IBS-secondary-to-PTSD claim, with evidence drawn largely from veteran populations.
Journal of Clinical Gastroenterology, 2022 · nexus to PTSD (post-traumatic stress disorder) · PMID 35089910
Finding: Among 184 veterans diagnosed with PTSD, 25% met Rome III criteria for IBS and rates of IBS and abdominal pain exceeded general US population reference values; greater PTSD severity was significantly associated with worse constipation, diarrhea, and gas/bloating after adjustment for age and sex.
Why it helps: Veteran-specific evidence supporting an association between PTSD severity and IBS/GI symptom burden, reinforcing an IBS-secondary-to-PTSD theory of service connection.
