The acid reflux started quietly—a burning sensation after meals, trouble sleeping, a persistent feeling that something was wrong in the gut. For many Veterans already battling PTSD, gastrointestinal symptoms like these become part of the daily burden. What most don’t realize is that there’s a direct biological connection between PTSD and gastroesophageal reflux disease (GERD)—and that connection may entitle them to additional disability compensation.
Understanding how to document that link is the first step toward benefits that are rightfully earned.
The Law Office of Sean Kendall has spent decades in the trenches with Veterans fighting for claims the U.S. Department of Veterans Affairs (VA) denied, underpaid, or simply misunderstood. A secondary GERD VA claim is exactly the kind of case where the right evidence and the right legal guidance can turn a rejection into a win. Here’s what you should know.
What Makes GERD a Secondary Condition to PTSD?
Secondary service connection means that a current disability—in this case, GERD—was caused or aggravated by an already service-connected condition, such as PTSD. Veterans don’t need to show that combat or military service directly caused their acid reflux. They need to show that their PTSD did.
This distinction matters. The VA routinely grants PTSD at various disability ratings while overlooking downstream physical conditions that stem directly from it. GERD is one of the most common (and overlooked) secondary conditions Veterans experience.
How PTSD Physically Disrupts the Digestive System
PTSD isn’t exclusively a psychological condition. It produces measurable, documented changes in how the body operates, including the gastrointestinal system. Chronic stress and anxiety associated with PTSD dysregulate the autonomic nervous system, which plays a central role in controlling digestion, gastric acid production, and the function of the lower esophageal sphincter (LES). When the LES doesn’t close properly, stomach acid flows back into the esophagus, causing the heartburn, regurgitation, and chest discomfort that define GERD.
Medical literature confirms a direct association between PTSD and heightened visceral sensitivity: meaning Veterans with PTSD experience gastrointestinal symptoms more frequently and more severely than the general population.
When Alcohol Use Disorder Is Part of the Picture
Many Veterans develop alcohol use disorder (AUD) as a coping mechanism for PTSD. Unfortunately, alcohol compounds the GERD problem significantly. Alcohol relaxes the LES, increases gastric acid secretion, and irritates the esophageal lining directly. Chronic alcohol use weakens the body’s natural defenses against acid reflux and can cause persistent reflux symptoms even when other factors are controlled.
When AUD is itself connected to a Veteran’s PTSD—which courts and medical experts recognize is often the case—the physiological pathway from PTSD to GERD becomes even more clearly established. Both PTSD-related stress and alcohol-related gastrointestinal irritation independently cause, and together they create a compounding effect.
Building a successful secondary GERD VA claim means presenting a coherent body of evidence that shows the VA exactly how PTSD caused or worsened the Veteran’s GERD. Incomplete claims rarely win. Documented, well-supported claims often do.
What Evidence Does a Secondary GERD VA Claim Require?
Your claim needs these core elements:
- A GERD diagnosis. Medical records confirming a GERD diagnosis from a licensed health care provider—VA or private—are the foundation of any claim. Records should reflect the onset, frequency, and severity of symptoms.
- A service-connected PTSD rating. The VA must have already granted PTSD as a service-connected condition. Without that anchor, a secondary claim has nowhere to attach.
- Medical evidence linking PTSD to GERD. Treatment records, clinical notes, and research supporting the physiological relationship between PTSD and gastrointestinal dysfunction help establish plausibility—but they’re not enough on their own.
- A nexus letter from a qualified medical professional. This is often the single most important document in a secondary claim. These letters state, in medical terms, that it is “at least as likely as not” that the Veteran’s service-connected PTSD caused or aggravated the GERD.
- Lay statements. Personal accounts from you and supporting witnesses describing the timeline of symptoms, their relationship to PTSD episodes, and the impact on daily life carry real weight at the VA.
Why the Nexus Letter Makes or Breaks the Claim
Not all nexus letters are created equal. A letter that simply states a Veteran has both PTSD and GERD, without explaining the causal mechanism, will likely fail. A strong nexus letter addresses the specific biological pathways:
- The autonomic nervous system dysregulation
- Chronic PTSD-related stress causes.
- The resulting increase in gastric acid production.
- The lower esophageal sphincter’s impairment.
- When relevant, how PTSD-associated alcohol use compounds each of those effects.
Physicians who understand VA claim standards and who are willing to use the appropriate “at least as likely as not” language are invaluable. The Law Office of Sean Kendall works with a network of medical experts who know how to write opinions that meet VA evidentiary standards and hold up under scrutiny.
Expert Opinions Can Change the Outcome
For claims the VA has already denied, or when their own medical examination produced an unfavorable opinion, an independent expert assessment may be the deciding factor. When physicians with knowledge of both the underlying conditions and VA adjudication standards prepare these opinions, they can directly rebut negative C&P exam findings and provide the evidentiary foundation a secondary claim needs to succeed.
Don't Let a Denied Claim Be the Final Word
GERD is painful, disruptive, and—when connected to PTSD—entirely compensable under VA disability law. Veterans who have already established a PTSD rating and are living with acid reflux, chronic heartburn, or related gastrointestinal symptoms have legal options. The claims process is rarely simple, but the right legal guidance makes it manageable.
Sean Kendall, Attorney at Law, has advocated for Veterans for decades, and that experience translates directly into results for clients navigating secondary claims. A secondary GERD VA claim is winnable with the right evidence, the right nexus letter, and the right advocate in your corner.
