GERD (gastroesophageal reflux disease, or acid reflux) is one of the most underrated secondary conditions in VA claims. It's commonly paired with PTSD, MST, and anxiety — yet most veterans don't file for it. GERD is also presumptive for Agent Orange exposure under the PACT Act (2022) and for certain burn pit exposures. If you have PTSD, military sexual trauma, or served in Vietnam, this guide shows you how to rate GERD, build a nexus for secondary service connection, and potentially unlock an automatic approval.
GERD (gastroesophageal reflux disease) is chronic acid reflux — stomach acid flows backward into the esophagus, causing burning, regurgitation, throat irritation, and sometimes severe pain or dysphagia (difficulty swallowing).
Common symptoms include:
Heartburn or chest pain (often mistaken for cardiac issues)
Regurgitation of food or liquid
Difficulty swallowing (dysphagia)
Hoarse voice or chronic cough
Nausea or feeling of food stuck in throat
Sleep disruption (reflux worsens when lying down)
Why veterans develop GERD at elevated rates:
Chronic stress and PTSD — stress hormones increase stomach acid production and impair esophageal sphincter function
MST (Military Sexual Trauma) — anxiety and trauma-related stress trigger acid reflux
Anxiety and panic disorder — can directly cause or worsen reflux
Sleep disruption — common in PTSD and reduces esophageal acid clearance
Medication side effects — some VA psychiatric medications increase reflux risk
Agent Orange exposure — presumptive under PACT Act (see below)
Burn pit and inhalation exposures — can irritate GI tract over time
GERD Is Rated Under 38 CFR § 4.71a, Diagnostic Code 7346
Criteria: Intermittent or occasional GERD symptoms managed with antacids or dietary modification alone; minimal medication use; no significant functional impairment.
Secondary Service Connection — The Most Common Path to GERD Approval
Secondary service connection under 38 CFR § 3.310 is how most veterans successfully claim GERD. If you have a service-connected condition that causes or aggravates GERD, you can file GERD as secondary.
GERD Secondary to PTSD (Strongest Nexus)
Mechanism: Chronic PTSD → elevated cortisol and stress hormones → increased stomach acid production and impaired esophageal sphincter function → GERD.
GERD secondary to PTSD is one of the strongest secondary connections because:
Medical literature extensively documents the stress-reflux link
Both conditions often co-occur in veterans
The biological pathway is well-established
VA examiners are familiar with this nexus
What your nexus letter needs to say: "The veteran's service-connected PTSD causes chronic stress, hyperarousal, and sleep disruption. These factors directly worsen stomach acid production and esophageal acid clearance, resulting in GERD. The temporal relationship [PTSD worsened around X date; GERD symptoms began around Y date] supports causation."
GERD Secondary to MST (Military Sexual Trauma)
MST causes severe anxiety and PTSD symptoms, which trigger GERD the same way. File GERD as secondary to MST-related PTSD or anxiety disorder.
GERD Secondary to Anxiety or Panic Disorder
If you have a service-connected anxiety disorder (DC 6110, etc.), file GERD as secondary. Anxiety directly triggers acid reflux.
GERD Secondary to IBS (Digestive Cascade)
If you have service-connected IBS (DC 7319), you can file GERD as secondary. Both often share the same root cause (stress, MST, toxic exposure) and can aggravate each other.
📋 Nexus Letter for GERD
Need a VA-experienced doctor to explain your GERD-to-service connection?
REE Medical provides nexus letters for GERD secondary to PTSD, MST, anxiety, and Agent Orange exposure. Proven track record with VA disability claims.
If you served in Vietnam (or Cambodia, Laos — affected areas):
GERD is presumptively service-connected — no nexus letter required
You only need to prove: (1) service in affected area, (2) current GERD diagnosis from a physician
Approval rate is extremely high
Check your eligibility immediately if: You served in Vietnam, operated helicopters that sprayed or transported Agent Orange, served on riverine boats in Vietnam, served in adjacent areas, or worked in maintenance/support roles near contaminated areas.
Burn Pit Exposure & Inhalation Hazards
GERD is also recognized as related to burn pit exposure (Iraq/Afghanistan 2003–present) and other inhalation exposures. While not yet presumptive for all burn pit veterans, a nexus showing GI effects from inhalation injury strengthens claims significantly.
Nexus Letter Strategy for GERD Secondary Service Connection
Since most GERD cases go through secondary service connection, your nexus letter is critical. Here's what it must include:
1. Current GERD Diagnosis and Severity
Your nexus letter should state: "Based on clinical evaluation and review of medical records, the veteran meets diagnostic criteria for GERD. Current treatment includes [medication list], and the veteran reports symptoms [specific: reflux X times/week, sleep disruption, chest pain on X days/week]."
2. Service-Connected Trigger Condition
Examples: "The veteran has service-connected PTSD (rated 50%)," or "The veteran has documented MST and service-connected anxiety disorder."
3. Biological Mechanism (The Critical Link)
Don't just say they co-occur. Explain causation:
"The veteran's PTSD is characterized by chronic hyperarousal, sleep disruption, and elevated cortisol. These factors are known to increase gastric acid secretion and impair lower esophageal sphincter (LES) function, resulting in reflux. The veteran's GERD symptoms worsened coinciding with PTSD symptom exacerbations, supporting a direct causal relationship."
4. Temporal Relationship
Show timeline: "Service-connected PTSD was diagnosed in [date]. GERD symptoms began or significantly worsened in [date], approximately [timeframe] after PTSD onset/exacerbation."
5. Ruling Out Alternative Causes
Good nexus letters address this: "While GERD can have multiple causes, the veteran's onset and severity pattern is consistent with stress-induced reflux. There is no evidence of primary esophageal dysmotility or anatomical abnormality; the primary driver is stress and anxiety from service-connected PTSD."
What Evidence the VA Requires for GERD Claims
Current GERD diagnosis from a physician (VA or civilian)
Medical records documenting symptoms and treatment — medication history, office notes describing reflux frequency/severity
Proof of in-service trigger or service-connected condition — DD214, PTSD or anxiety diagnosis documentation, MST report if applicable
Nexus letter — medical opinion explaining the connection
C&P exam report — VA examiner's documentation of symptoms and severity
Symptom diary — your own documentation of reflux episodes, triggers, medication use, functional impact
Medication list — proof of ongoing acid-suppressing therapy (PPIs, H2-blockers)
Endoscopy or imaging reports (if applicable) — documenting esophageal damage or Barrett's esophagus for higher ratings
Preparing for the GERD C&P Exam
Before the Exam
Keep a 2–3 week symptom diary: Document daily reflux episodes (time of day, severity 0–10, trigger, symptoms, medication taken)
Note sleep disruption: How many nights per week does reflux wake you? How does it affect sleep quality?
Document dietary restrictions: Foods you avoid, weight loss due to dietary changes, impact on social eating
Bring medication list — show frequency and dosing of acid-suppressing medications
Prepare a one-page summary of your worst GERD days in the past month
During the Exam
Be specific about frequency: Don't say "sometimes I have reflux." Say "I have reflux 4–5 days per week, usually at night and after large meals."
Describe severity and functional impact: "Reflux wakes me 2–3 times per week. I've had to change my diet significantly — I avoid citrus, spicy foods, alcohol. I can't eat past 7 p.m. or it triggers pain."
Link to stress/PTSD if applicable: "My reflux flares when my PTSD symptoms worsen. If I'm stressed or having nightmares, the reflux is worse the next day."
Describe work/social impact: "I've had to take sick days when reflux is severe. I can't eat lunch with coworkers without pain or embarrassment."
After the Exam
Request a copy of the C&P report
If the report doesn't reflect your reported symptoms accurately, file a supplemental claim with a personal statement correcting the record
GERD Often Pairs With Other Ratable Conditions
When filing GERD, also look for related conditions to file simultaneously:
Anxiety/panic disorder (DC 6110) — directly worsens GERD; file both
IBS/digestive conditions (DC 7319) — common co-morbidity; both from stress/trauma
Sleep apnea (DC 6847) — reflux worsens when lying flat; sleep deprivation worsens acid production
Depression (DC 6100) — often paired with PTSD; can worsen appetite and nutrition, affecting GI health
Combined rating strategy: Filing GERD + PTSD + anxiety + IBS can produce a combined rating of 60%–80%, even if each individual condition rates 20–30%.
💡 Pro Tip: Secondary to Secondary
You can file GERD as secondary to anxiety, and anxiety as secondary to PTSD. Each connection strengthens the others. A strong claim chain (PTSD → anxiety → GERD) shows the cascading effects of service-connected disability.
