GERD Secondary to PTSD: Building the Connection

If you have a service-connected mental health condition like PTSD and you also deal with chronic heartburn, regurgitation, or that burning feeling in your chest, you may be able to file for GERD as a secondary condition. The link between stress, anxiety, and acid reflux is well documented in medical research — but the VA won't connect the dots for you. You have to build the case. This guide walks through how GERD is rated, the medical theory tying it to PTSD, and exactly what evidence makes a secondary service connection GERD claim stronger.

How GERD is rated under the digestive schedule

Gastroesophageal reflux disease (GERD) does not have its own diagnostic code in the VA rating schedule. Instead, the VA rates it by analogy — usually under the criteria for a hiatal hernia at 38 CFR § 4.114, Diagnostic Code 7346. When a condition isn't listed, the rater picks the closest matching condition, a practice authorized under 38 CFR § 4.20.

Under Diagnostic Code 7346, the ratings break down like this:

In plain terms: the more symptoms you have, how often they hit, and how much they wreck your overall health, the higher the rating. "Pyrosis" just means heartburn. "Dysphagia" means trouble swallowing. "Regurgitation" is food or acid coming back up.

A quick note on a 2024 change: the VA updated portions of the digestive rating schedule. GERD continues to be rated by analogy, so the practical takeaway hasn't changed — document the full picture of your symptoms so the rater can match them to the right level. If you want to see how a GERD rating would stack with your other conditions, run the numbers through our VA Disability Calculator, which uses VA combined-ratings math.

The medical theory linking PTSD and GERD

A secondary claim only works if there's a sound medical reason to connect the two conditions. For GERD secondary to PTSD, there are two main pathways, and you can argue both.

Pathway 1 — The body's stress response. Chronic stress and anxiety, which are hallmarks of PTSD, affect the digestive system. Stress can increase stomach acid production, slow down how fast the stomach empties, and relax the lower esophageal sphincter — the valve that's supposed to keep stomach contents from flowing backward. When that valve loosens, acid escapes upward, and that's reflux. Medical literature has repeatedly observed higher rates of GERD and other gastrointestinal complaints among people with PTSD and anxiety disorders.

Pathway 2 — Medication side effects. This is its own pathway and we cover it in detail below, but it's worth flagging here: many drugs prescribed for PTSD can irritate the stomach or weaken that same valve.

You don't have to be a doctor to claim this. You just need a medical professional to explain the connection in your specific case. To explore other conditions that commonly stem from PTSD, browse our Secondary Conditions guide.

What a nexus opinion needs to say

The nexus opinion is the heart of a secondary claim. Under 38 CFR § 3.310, a condition can be service-connected if it is proximately due to or the result of a service-connected disability — and that also covers aggravation, where the service-connected condition makes a non-service-connected condition worse.

A strong nexus letter from a doctor should hit these points:

• •Clear identification of both conditions: the diagnosed GERD and the service-connected PTSD.
• •The opinion language. The examiner should state it is at least as likely as not (a 50% or greater probability) that the GERD was caused or aggravated by the PTSD. This phrasing matters because the VA's standard of proof is the benefit-of-the-doubt rule under 38 CFR § 3.102 — you only need the evidence to be in equipoise, not a slam dunk.
• •The rationale. This is what separates a winning opinion from a rubber stamp. The doctor should explain why — referencing the stress-and-acid mechanism, medication effects, the timeline of your symptoms, or medical literature. The Court of Appeals for Veterans Claims has made clear (in Nieves-Rodriguez v. Peake, 22 Vet. App. 295) that the weight of a medical opinion comes from its reasoning, not just its conclusion.
• •Review of your records. The opinion carries more weight when the provider shows they reviewed your relevant history.

Before you submit, an Evidence Gap Analyzer review can flag whether your nexus and supporting records are missing anything an adjudicator will look for.

The role of medication side effects

The medication pathway is one of the most overlooked — and most persuasive — arguments in a GERD secondary to PTSD claim. The legal basis here is the same § 3.310, because the VA recognizes that a disability caused by the treatment for a service-connected condition can itself be service-connected.

Many medications commonly prescribed for PTSD are known to cause or worsen reflux symptoms. These can include certain antidepressants (SSRIs and SNRIs), and especially NSAIDs or pain relievers taken for related issues, which irritate the stomach lining. Some sedatives and muscle relaxants can also relax the esophageal sphincter.

To build this argument:

• •Pull your prescription history showing which PTSD-related medications you take and for how long.
• •Note the timeline — did your reflux start or worsen after you began a particular medication?
• •Ask your prescriber or pharmacist to comment on whether your medication is a known contributor to GERD.

When you go in for your exam, be ready to explain this clearly. Our C&P Exam Simulator lets you practice talking through your symptoms and their causes so nothing important gets left out.

Evidence that strengthens the secondary claim

A secondary claim lives or dies on documentation. Here's what builds a complete file:

• •A current GERD diagnosis. You need a confirmed diagnosis — typically from a primary care provider, gastroenterologist, or an endoscopy. Self-reported heartburn alone isn't enough to establish the disability.
• •Established service connection for PTSD. The PTSD must already be service-connected (or claimed at the same time). If it isn't yet, that's the first domino.
• •The nexus opinion described above.
• •Treatment records showing ongoing reflux symptoms, prescribed acid reducers (like proton pump inhibitors), and how the symptoms affect your daily life.
• •A lay statement from you, and ideally a buddy or spouse, describing the frequency and severity of symptoms — nighttime regurgitation, trouble swallowing, sleep disruption, dietary restrictions. Lay evidence is competent to describe symptoms you can observe and feel.
• •Medication records tying PTSD treatment to stomach problems.

To prepare for the exam that ties this all together, build a condition-specific guide with our C&P Exam Prep tool. And if you have an existing C-File, the C-File Analyzer can surface gaps and conditions you may not have claimed yet.

Common denial reasons and how to address them

Understanding why these claims get denied helps you head off problems before they start.

"No nexus / no medical link established." This is the most common reason. The fix is a thorough nexus opinion with real rationale — not just a checkbox. If your denial cites a weak or missing opinion, get a stronger one that explains the medical mechanism.

"GERD is due to non-service-connected factors." Raters may point to obesity, diet, smoking, or alcohol as alternative causes. You can respond two ways: have your provider address those factors and explain why PTSD is still at least an equal contributor, and lean on the aggravation theory under § 3.310 — even if other factors play a role, PTSD or its medications can still make the GERD worse.

"The C&P examiner gave a negative opinion." A negative exam opinion isn't the end. You can submit a private nexus opinion to compete with it; the VA must weigh both. If the examiner ignored your medication history or didn't review your file, point that out.

"PTSD wasn't service-connected at the time." A secondary claim needs an underlying service-connected condition. If your PTSD claim is still pending, that's the priority.
