GERD Secondary to PTSD

Overview

Gastroesophageal reflux disease (GERD) is a chronic digestive condition in which stomach acid frequently flows back into the esophagus, causing heartburn, regurgitation, and damage to the esophageal lining. For veterans with PTSD, GERD is among the most frequently claimed secondary conditions — and for good reason. The medical link between chronic psychological stress and gastrointestinal dysfunction is well established.

The VA rates GERD under Diagnostic Code 7346 (hiatal hernia), which covers a range of upper gastrointestinal symptoms. While the average rating is 10%, veterans with more severe symptoms can receive 30% or even 60%.

Filing GERD as secondary to PTSD requires demonstrating a medical connection between the two conditions through a nexus letter and supporting evidence.

How GERD Is Connected to PTSD

The relationship between PTSD and GERD is supported by multiple physiological pathways documented in peer-reviewed medical literature.

Autonomic nervous system dysregulation. PTSD keeps the sympathetic nervous system chronically activated. This disrupts normal gastrointestinal function by altering gastric acid secretion, esophageal motility, and lower esophageal sphincter pressure. Research published in Psychosomatic Medicine has demonstrated that chronic stress directly impairs the coordinated muscle movements that prevent acid reflux.

Increased gastric acid secretion. The chronic stress response associated with PTSD stimulates excess production of gastric acid through cortisol-mediated pathways. A study in the American Journal of Gastroenterology found that individuals with PTSD produce significantly more stomach acid than controls, contributing to erosive damage to the esophageal lining.

Visceral hypersensitivity. PTSD alters how the brain processes signals from the gastrointestinal tract, a phenomenon known as visceral hypersensitivity. Research in Neurogastroenterology & Motility shows that veterans with PTSD report more intense GI symptoms at lower levels of acid exposure compared to non-PTSD populations.

Medication side effects. SSRIs (sertraline, fluoxetine) and SNRIs (venlafaxine) commonly prescribed for PTSD can irritate the gastric mucosa and relax the lower esophageal sphincter, directly contributing to reflux. NSAIDs used for PTSD-related comorbid pain conditions further aggravate the stomach lining.

Behavioral factors. PTSD-related behaviors including increased alcohol consumption, tobacco use, irregular eating patterns, and stress eating can exacerbate GERD symptoms. While these behavioral pathways are secondary to the direct physiological link, they strengthen the overall connection.

Epidemiological evidence. A large VA study published in Alimentary Pharmacology & Therapeutics found that veterans with PTSD have significantly higher rates of GERD and other functional gastrointestinal disorders compared to veterans without PTSD, even after adjusting for lifestyle factors.

Evidence Requirements

To build a strong secondary claim for GERD linked to PTSD, you need the following:

• Current GERD diagnosis. A formal diagnosis from a physician, ideally supported by an esophagogastroduodenoscopy (EGD) or pH monitoring study. Even a clinical diagnosis based on symptoms and response to medication is acceptable.
• Proof of service-connected PTSD rating. Your VA rating decision letter confirming an active PTSD rating.
• Medical nexus letter. A physician’s opinion stating that your GERD is at least as likely as not caused by or aggravated by your PTSD.
• Treatment records showing GERD symptoms. Document your history of GERD treatment, including prescriptions for proton pump inhibitors (PPIs), H2 blockers, antacids, and any dietary modifications.
• Medication history. A list of PTSD medications you take or have taken, highlighting any known to contribute to gastrointestinal irritation.
• Symptom log. A personal record of reflux episodes, including frequency, severity, triggers, and impact on your daily life and diet.
• Buddy statements. Statements from family members who can describe your visible symptoms — taking medications before meals, avoiding certain foods, nighttime reflux episodes, or sleep interruptions from acid reflux.

Nexus Letter Tips

A strong nexus letter is critical for connecting your GERD to your PTSD. Here is what to look for:

Who should write it. A gastroenterologist provides the most credible opinion, but any licensed physician or doctor of osteopathy can write an effective nexus letter. A physician familiar with both your PTSD treatment and GI symptoms is ideal.

Key language to include. The letter must state that your GERD is “at least as likely as not” (50% or greater probability) caused by or aggravated by your service-connected PTSD. This is the VA’s required legal standard for service connection.

What the letter should address:

• Your PTSD diagnosis and symptom profile, including hyperarousal and chronic stress
• The specific medical mechanisms linking PTSD to GERD (autonomic dysfunction, acid hypersecretion, medication effects)
• A review of your medical records documenting both conditions
• Reference to peer-reviewed studies supporting the PTSD–GERD connection
• Discussion of why your GERD is not solely attributable to other causes
• If applicable, how PTSD medications specifically contribute to your reflux symptoms

Common mistakes to avoid. Avoid vague language like “could possibly be related.” The nexus opinion must be firm. Also avoid nexus letters that fail to cite specific medical literature — the VA weighs evidence-based opinions more heavily.

Rating Criteria for GERD

GERD is rated under DC 7346 (hiatal hernia) using the following criteria:

10% Rating

Two or more of the symptoms required for a 30% rating, but with less severity. This typically includes recurrent heartburn, regurgitation, or mild dysphagia managed with daily medication.

Monthly compensation at 10% (single veteran, no dependents, 2026): $180.42

30% Rating

Persistently recurrent epigastric distress with dysphagia (difficulty swallowing), pyrosis (heartburn), and regurgitation, accompanied by substernal or arm or shoulder pain, productive of considerable impairment of health.

60% Rating

Symptoms of pain, vomiting, material weight loss, and hematemesis (vomiting blood) or melena (blood in stool) with moderate anemia; or other symptom combinations productive of severe impairment of health.

Important Notes on Rating

The VA rates GERD based on the overall impact of your symptoms on your health, not just individual symptoms in isolation. Document the frequency, severity, and functional impact of every GI symptom you experience. Many veterans are initially rated at 10% but may qualify for a higher rating if their symptoms are well-documented.

How to File This Secondary Claim

Follow these steps to file a secondary claim for GERD connected to PTSD:

1. Confirm your GERD diagnosis. If you do not have a formal GERD diagnosis, see your primary care physician or a gastroenterologist. Describe all symptoms including heartburn, regurgitation, chest pain, difficulty swallowing, and nausea.
2. Verify your PTSD service connection. Check your VA rating decision letter to confirm your PTSD rating is active.
3. Obtain a nexus letter. Have a qualified physician write a nexus opinion connecting your GERD to your PTSD.
4. Compile supporting evidence. Gather your GI treatment records, PTSD medication list, symptom logs, and any endoscopy or pH monitoring results.
5. File VA Form 21-526EZ. Submit your claim through VA.gov or by mail. Select “secondary to a service-connected condition” and list PTSD as the primary condition linked to your GERD.
6. Upload all evidence. Attach your nexus letter, medical records, and supporting documents. Filing as a Fully Developed Claim (FDC) speeds up processing.
7. Attend your C&P exam. The VA will schedule a compensation and pension examination to evaluate your GERD and its connection to PTSD.

C&P Exam Tips

The C&P exam for GERD will evaluate the severity of your condition and its relationship to PTSD. Here is how to prepare:

• Describe the full range of symptoms. Report heartburn frequency, regurgitation episodes, difficulty swallowing, nausea, chest pain, throat irritation, and any impact on your diet or weight.
• Bring your medication list. Show all current and past medications for both GERD and PTSD. Highlight any PTSD medications that may contribute to GI symptoms.
• Explain the connection to PTSD. Be prepared to describe how your stress levels affect your reflux symptoms, and when your GERD symptoms began in relation to your PTSD.
• Report your worst symptoms. The VA rates based on overall impairment. Describe your symptoms on bad days, not just average days.
• Mention dietary restrictions. If GERD has forced you to change your diet, avoid certain foods, elevate your bed, or modify your eating schedule, tell the examiner.
• Do not minimize. Many veterans downplay GI symptoms because they seem minor compared to PTSD. Every symptom matters for your rating.

Impact on Combined Rating

Adding a GERD rating to an existing PTSD rating increases your combined disability. Here is how the math works:

Example: A veteran with a 70% PTSD rating who receives a 10% rating for GERD secondary to PTSD.

Using the VA’s whole person method (38 CFR Section 4.25):

1. Start with the highest rating: 70% disabled, 30% healthy
2. Apply the next rating to the remaining healthy percentage: 10% of 30% = 3%
3. Total disability: 70% + 3% = 73%
4. Rounded to the nearest 10%: 70% combined rating

In this example, the 10% GERD rating alone does not push the combined rating above the 70% rounding threshold. However, if the veteran has additional rated conditions, the GERD rating contributes to the cumulative calculation and can push the overall combined rating to a higher tier.

Example with additional condition: A veteran rated 70% for PTSD and 10% for tinnitus who adds a 10% GERD rating:

1. Start with 70%: 30% healthy
2. Apply 10% tinnitus: 10% of 30% = 3%, total = 73%, 27% healthy
3. Apply 10% GERD: 10% of 27% = 2.7%, total = 75.7%
4. Rounded to the nearest 10%: 80% combined rating
