Can GERD be service-connected secondary to PTSD?

Yes. GERD is commonly claimed secondary to PTSD because the chronic stress response disrupts gastrointestinal motility, increases stomach acid production, and weakens the lower esophageal sphincter. The VA accepts this connection when supported by a nexus opinion.

What VA rating does GERD receive?

GERD is rated under Diagnostic Code 7346 (Hernia, hiatal) or Diagnostic Code 7319 (Irritable colon syndrome) depending on how the examiner characterizes it. Ratings range from 10% to 60% based on frequency of symptoms, weight loss, and response to treatment.

How do I prove GERD is caused by my PTSD?

The key evidence is a nexus letter from a licensed physician explaining the gut-brain axis connection between chronic psychological stress and gastrointestinal dysfunction. Supporting VA treatment records documenting concurrent PTSD and GI symptoms are also important.

Is medication enough to deny my GERD claim?

No. The VA rates GERD based on the level of severity and symptom frequency regardless of whether it is managed with medication. Well-controlled GERD may receive a lower rating, but the condition is still ratable.

What if my C&P examiner said there is no nexus?

A negative C&P opinion is not the end. File a Supplemental Claim with a private nexus letter that specifically rebuts the C&P examiner's reasoning. Many veterans succeed on the second attempt with stronger medical evidence.

What Is GERD Secondary to PTSD?

Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid flows back into the esophagus, causing heartburn, chest pain, regurgitation, and over time, serious complications like esophagitis and Barrett's esophagus. For veterans with PTSD, this condition is more than coincidence — the same stress-response systems that keep veterans in a state of hyperarousal also directly disrupt normal gastrointestinal function.

The gut-brain connection is one of the most extensively studied areas in modern gastroenterology. The enteric nervous system — often called the "second brain" — is profoundly influenced by the state of the central nervous system. When PTSD keeps the brain in chronic threat-response mode, the gut responds in kind: motility changes, acid production increases, and the lower esophageal sphincter (the valve that prevents acid reflux) becomes less effective.

Filing GERD as a secondary condition to PTSD is a recognized pathway that many veterans have pursued successfully. The claim does not require proving PTSD is the only cause — only that it contributed to or worsened the condition.

Why the VA Recognizes This Connection

Gut-brain axis dysregulation. The vagus nerve serves as the primary bidirectional communication channel between the brain and gut. PTSD-driven autonomic nervous system dysregulation interferes with normal vagal tone, which in turn disrupts the coordinated muscle contractions that move food through the GI tract and protect the esophagus from acid exposure.

Cortisol and gastric acid. Chronic psychological stress is associated with increased gastric acid secretion. Elevated cortisol can disrupt the mucosal barrier that normally protects the esophageal lining, leaving it more vulnerable to acid damage.

Eating patterns and behaviors. Veterans with PTSD often experience disordered eating patterns — irregular meal timing, stress eating, alcohol use, and poor diet — that are recognized contributors to GERD. These behaviors are direct symptoms of PTSD's behavioral effects, not independent lifestyle choices.

Medication effects. Antidepressants (particularly SSRIs and SNRIs) and benzodiazepines prescribed for PTSD can alter GI motility and sphincter function, contributing to reflux symptoms.

Studies have shown a statistically significant association between PTSD and functional gastrointestinal disorders, including GERD. The VA's disability evaluation system recognizes GI conditions as ratable secondary conditions, and the VA's resources on PTSD-related conditions acknowledge the wide-ranging physiological effects of the disorder.

Evidence That Wins This Claim

Endoscopy or GI diagnostic records: Formal diagnosis of GERD, esophagitis, or hiatal hernia from a gastroenterologist or primary care provider establishes the condition.
PTSD service connection documentation: Rating decisions and C&P exam reports proving your PTSD is already service-connected anchor the secondary claim.
Private nexus letter: A physician's opinion stating "at least as likely as not" that your PTSD caused or aggravated your GERD. The letter should explain the gut-brain mechanism clearly.
VA treatment records: Documentation of GI symptoms discussed in the context of VA mental health care — particularly if a VA provider noted the connection.
Medication history: Records showing GERD medications (PPIs, H2 blockers) prescribed during or after PTSD onset and treatment.
GI symptom diary: A personal log of symptom frequency and severity can support the claim, particularly if formal records are sparse.
Buddy statements: Family members who observed dietary changes, discomfort, or symptoms concurrent with PTSD episodes can provide corroborating lay evidence.

How the VA Rates GERD

GERD is typically rated under Diagnostic Code 7346 (Hiatal Hernia) or 7319 (Irritable Colon Syndrome) depending on the presentation. Under DC 7346:

Rating	Criteria
60%	Symptoms of pain, vomiting, weight loss, and hematemesis or melena with moderate anemia; or other symptom combinations productive of severe impairment of health
30%	Persistently recurrent epigastric distress with dysphagia, pyrosis, and regurgitation, accompanied by substernal or arm or shoulder pain, productive of considerable impairment of health
10%	With two or more of the symptoms for the 30% evaluation of less severity

Most veterans with well-documented GERD secondary to PTSD receive 10% to 30% ratings. The key is demonstrating persistent, recurring symptoms that affect daily function.

Why These Claims Get Denied — And How to Prevent It

Failure to submit a nexus letter. The VA does not draw the PTSD-GERD connection automatically. Without a physician's opinion, the claim will be denied on the grounds that the conditions are unrelated.

Thin diagnostic record. GERD managed informally — with over-the-counter antacids and no formal medical visits — provides an insufficient documentation trail. Seek formal evaluation and keep records.

General risk factors cited. C&P examiners sometimes attribute GERD to diet, weight, or caffeine use without engaging with the PTSD secondary theory. A detailed nexus letter preemptively addresses this by establishing the PTSD mechanism specifically.

Incorrect diagnostic code. If GERD is evaluated under a code with narrower criteria, ratings may be lower than warranted. Consider consulting with a VSO or claims agent who can argue for the most favorable applicable code.

Isolated C&P opinion. Some C&P examiners lack gastroenterology expertise and may provide cursory opinions. Submitting a private nexus letter before the C&P exam establishes the evidentiary record the examiner must address.

Sample Nexus Letter Language

"I have reviewed [Veteran's name]'s medical records, including VA documentation of service-connected PTSD and gastroenterology records confirming a diagnosis of GERD. In my professional medical opinion, it is at least as likely as not that [Veteran's name]'s GERD was caused or materially aggravated by their service-connected PTSD. The chronic stress response associated with PTSD is well-documented to disrupt gastrointestinal function through vagal dysregulation, altered gastric acid secretion, and increased esophageal acid exposure. The temporal relationship between [Veteran's name]'s PTSD onset and the development of persistent GI symptoms further supports this conclusion."
