Gastroesophageal reflux disease (GERD) is a common health issue among veterans, often occurring as a secondary condition related to other service-connected disabilities. While GERD itself can be uncomfortable and disruptive, understanding the underlying causes can help veterans seek appropriate medical care and potential disability benefits. Leah Bucholz will explore the top three veteran health issues that cause GERD: mental health conditions, chronic pain, and obesity.

1. Mental Health Conditions (PTSD, Anxiety, and Depression)
Many veterans struggle with mental health conditions such as post-traumatic stress disorder (PTSD), anxiety, and depression. Research has shown a strong correlation between these conditions and GERD. The heightened stress and anxiety associated with these disorders can lead to an overproduction of stomach acid, increasing the likelihood of acid reflux.
How Mental Health Conditions Contribute to GERD
- Increased Stomach Acid Production: PTSD and anxiety trigger the body’s stress response, leading to excessive acid production, which can irritate the esophagus.
- Disrupted Digestive Processes: Stress can interfere with normal digestion, slowing down stomach emptying and increasing the risk of acid reflux.
- Unhealthy Coping Mechanisms: Veterans with PTSD or anxiety may engage in behaviors that exacerbate GERD, such as smoking and alcohol consumption. Smoking weakens the lower esophageal sphincter, while alcohol increases stomach acid production and relaxes the sphincter, making reflux more likely.
- Poor Sleep Patterns: Sleep disturbances are common in veterans with PTSD, and lying down at night can worsen GERD symptoms due to acid backflow.
2. Chronic Pain and Medication Use
Chronic pain is another major factor contributing to GERD among veterans. Many veterans experience ongoing pain due to service-related injuries, including back pain, knee pain, and musculoskeletal conditions. The medications used to manage this pain, particularly non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, can lead to GERD.
How Chronic Pain and Medications Cause GERD
- NSAID Use: NSAIDs, such as ibuprofen and aspirin, are commonly prescribed for pain management but can irritate the stomach lining, reducing its ability to protect itself from acid.
- Opioid Use: Long-term opioid use slows down the digestive process, leading to delayed gastric emptying and increased risk of acid reflux.
- Stress and Pain Connection: Chronic pain activates the body’s stress response, which, as previously mentioned, can increase stomach acid production and worsen GERD symptoms.
3. Obesity and Weight Gain
Obesity is a well-documented risk factor for GERD. Many veterans struggle with weight gain due to service-related physical limitations, chronic pain, and medication side effects. Additionally, mental health conditions may contribute to unhealthy eating habits and reduced physical activity, further exacerbating weight gain.
How Obesity Causes GERD
- Increased Abdominal Pressure: Excess weight around the abdomen puts pressure on the stomach, pushing acid up into the esophagus.
- Weakened Lower Esophageal Sphincter: Obesity can cause the muscle responsible for preventing acid reflux to weaken, making reflux more frequent and severe.
- Compounding Health Conditions: Obesity is often associated with conditions like sleep apnea and hypertension, both of which can make GERD symptoms worse.
Top 3 Veteran Health Issues That Cause GERD – Conclusion
GERD is a significant health concern for many veterans, often developing as a secondary condition related to mental health disorders, chronic pain, and obesity. Understanding these contributing factors can help veterans seek appropriate medical treatment and, if applicable, apply for VA disability benefits. If you believe your GERD is related to a service-connected condition, discussing these factors with your healthcare provider may help support your claim for benefits.
