Anxiety doesn't directly cause reflux the way a weak LES or a hiatal hernia does, but it has several real, indirect pathways that can trigger or worsen symptoms, which is why the two so often show up together.
How anxiety affects the digestive system
Stress hormones can slow stomach emptying and may increase sensitivity to acid in the esophagus, meaning the same amount of reflux can feel more intense and be noticed more readily during periods of anxiety. Anxiety can also lead to behaviors that worsen reflux — eating quickly, skipping meals then overeating later, or increased alcohol or caffeine intake as coping mechanisms.
The relationship runs both ways
Just as anxiety can worsen reflux, dealing with chronic, uncomfortable reflux symptoms can itself increase anxiety, particularly around eating or sleeping, creating a cycle that's worth addressing from both directions rather than just one.
What helps both
Stress-reduction practices like diaphragmatic breathing, regular exercise, and adequate sleep support both anxiety and reflux symptoms simultaneously, since they address a shared underlying pathway rather than treating them as entirely separate issues.
