Agent Orange Exposure Is Not a Recognized Risk Factor for Gastroesophageal Reflux Disease (GERD)

Evidence from Authoritative GERD Guidelines

The American Gastroenterological Association, American College of Gastroenterology, and Italian consensus guidelines do not list environmental toxin exposure, herbicides, or dioxins (including Agent Orange) as contributing factors to GERD development【1】【2】【3】.
Anatomical factors such as hiatal hernia are identified as GERD risk factors in the American College of Gastroenterology guideline【1】.

GERD is highly prevalent in the United States, with ≈50 % of adults experiencing monthly symptoms and ≈20 % reporting weekly symptoms【1】.

Evaluation and treatment should follow standard evidence‑based GERD guidelines (American College of Gastroenterology)【2】【3】.
Initial therapy: a 4–8‑week trial of once‑daily proton‑pump inhibitor (PPI) is recommended【4】.
Endoscopic assessment is advised when alarm features are present (e.g., dysphagia, weight loss, gastrointestinal bleeding)【3】.
Causation statement: Current evidence does not support attributing GERD to Agent Orange exposure【1】.

While veterans may qualify for VA benefits for conditions documented as associated with Agent Orange (e.g., thyroid disorders, diabetes, neurologic diseases, COPD, liver disease), GERD is not included on that list based on existing epidemiologic data【1】.
