Early-2000s Marine veteran • Repeated in-service stomach complaints • Chronic reflux after deployment

The Challenge

The VA denied GERD because there was no formal in-service diagnosis. The STRs contained few notations of “stomach pain” and prescription of antacids.

What Existed Before

STR notations of GI discomfort
Post-service GERD diagnosis.

Our Contribution

Highlighted repeated GI complaints in STRs
Explained pathophysiology of chronic reflux
Demonstrated post-service continuity through medical records
Connected dietary exposure during deployment to symptom onset

Key Takeaway

Once the updated medical rationale and continuity-of-symptom documentation were submitted, the veteran later received a favorable VA decision granting primary service connection for GERD.
