Heartburn isn’t always caused by what you eat. For many Veterans, the burning sensation traces directly back to their military service and the post-traumatic stress disorder (PTSD) that followed them home. The connection between chronic stress and gastrointestinal problems is real, documented in medical literature, and recognized by the VA. However, Veterans must prove this secondary service connection.
When having the right legal guidance matters, call us. The Law Office of Sean Kendall has worked with Veterans nationwide on exactly these kinds of layered, evidence-heavy claims. Proving that gastroesophageal reflux disease (GERD) developed due to service-connected PTSD is achievable, but it takes a clear strategy. Here’s what you should know.
How Does PTSD Cause GERD?
PTSD isn’t just a psychological condition. It produces measurable physical changes throughout the body. The autonomic nervous system, which regulates functions like digestion and acid production, is directly affected by chronic stress and anxiety. In Veterans with PTSD, elevated stress hormones and persistent nervous system dysregulation increase stomach acid production and reduce the effectiveness of the lower esophageal sphincter, the muscle valve that prevents acid from flowing backward into the esophagus. When that valve is compromised, acid reflux follows.
PTSD is also associated with heightened visceral sensitivity, meaning the gastrointestinal tract becomes more reactive. Veterans with PTSD may experience more frequent and severe reflux symptoms than the general population, even when acid levels are comparable. Medical research supports a direct biological link between PTSD-related physiological changes and the development or worsening of GERD.
Alcohol use disorder, which commonly develops in Veterans as a coping mechanism for PTSD, adds another layer. Alcohol relaxes the lower esophageal sphincter, increases gastric acid secretion, and irritates the esophageal lining directly. When alcohol use is associated with service-connected PTSD, its gastrointestinal effects become part of the same causal chain.
According to the U.S. Department of Veterans Affairs (VA), its secondary service connection framework is designed to account for exactly this kind of linked condition.
What Is Secondary Service Connection for a VA Disability Claim?
Here’s why the legal standard matters for GERD claims. Secondary service connection allows a Veteran to receive disability compensation for a condition that an already-rated service-connected disability caused or worsened. If you already have a rating for PTSD, you can claim GERD as a secondary condition. You don’t need to show that military service caused your GERD—only that PTSD caused or aggravated it.
You need proof that establishes a reasonable probability, not certainty, of a causal relationship. This is a lower bar than many Veterans realize, but it still requires clear, well-documented evidence. A diagnosis alone isn’t enough. The VA needs a medical opinion that explains the mechanism linking the two conditions.
What Evidence Strengthens a Secondary GERD VA Claim?
Treatment records from primary care providers, gastroenterologists, or VA medical centers documenting GERD symptoms, diagnostic testing, and prescribed medications are essential. Records showing the timeline of GERD symptoms in relation to the onset or worsening of PTSD can be especially persuasive.
Veterans should gather every relevant record, including notes about:
- Heartburn
- Reflux
- Esophageal irritation
- Acid-related symptoms
Even routine records can demonstrate the chronic, ongoing nature of the condition and its impact on daily functioning.
The Nexus Letter Is the Core of Your Claim
A nexus letter is a written medical opinion prepared by a qualified physician or specialist that directly connects the secondary condition to the primary one. For a secondary GERD claim, the nexus letter should explain:
- The biological mechanism. This describes how PTSD affects the autonomic nervous system, stress hormone regulation, and lower esophageal sphincter function—establishing the physiological pathway between the two conditions.
- Your specific history. A strong nexus letter references your documented PTSD history, symptom timeline, and individual medical records to show how the causal pathway applies to you.
- Connection to alcohol use disorder (AUD). If applicable, diagnosed AUD tied to PTSD, the letter should address how that condition independently contributes to GERD through increased acid production and sphincter relaxation.
- Supporting medical literature. Citing peer-reviewed research that recognizes a link between PTSD and gastrointestinal conditions strengthens the opinion and makes it harder for the VA to dismiss.
The nexus letter doesn’t need to state that PTSD was the only cause of your GERD—only that PTSD was “at least as likely as not” a contributing cause. That phrase carries specific legal weight in VA adjudications.
Lay Evidence From the Veteran and Family Members
Buddy statements from people who know you well—such as family members, fellow Veterans, and caregivers—and your first-hand account help document the real-world impact of your GERD symptoms. These statements should describe observable symptoms, how those symptoms appeared or worsened alongside PTSD episodes, and how the condition affects your daily life.
The VA recognizes lay statements as evidence in its proceedings. While not a substitute for medical opinions, they add texture and credibility to a claim, particularly when they corroborate the timeline established in medical records.
What Happens If the VA Denies Your Secondary GERD Claim?
A denial from the VA isn’t the end of the road. Veterans who received denials or feel their rating doesn’t reflect the severity of their condition have real options. Sean Kendall, Attorney at Law, can help you:
- File a supplemental claim with new and relevant evidence.
- Request a higher-level review.
- Appeal to the Board of Veterans’ Appeals.
Each pathway has its own requirements and timelines, and choosing the right one depends on the specific reason for the denial.
If the VA based the denial on an inadequate nexus opinion or a flawed rating decision, a stronger independent medical opinion may be the key to overturning it. The U.S. Court of Appeals for Veterans Claims provides judicial review for cases that exhaust the administrative process—a forum that has been central to Sean’s practice since the court’s founding.
