Reducing over-alertness and stress responses that worsen acid reflux
Targeting Hypervigilance and Autonomic Arousal: the Psycho-physiologic Model of GERD
This work tests whether calming excessive vigilance and automatic stress reactions can help adults with GERD have fewer symptoms and better quality of life.

What this research studies
From a patient perspective, researchers are separating different types of acid reflux by measuring body signals and symptom patterns so treatments can be matched to the person. They are studying how being overly alert to symptoms and having a stressed autonomic nervous system (fast heart rate, sweating, etc.) make reflux feel worse. The team uses physiological tests, questionnaires about distress and symptom focus, and targeted behavioral or mind-body approaches to lower hypervigilance and autonomic arousal. Their earlier work developed new physiologic predictors and faster ways to phenotype patients to guide more personalized care.
Who could benefit from this research
Good fit: Adults (21+) with ongoing GERD symptoms, especially those who report high worry about symptoms or physical signs of autonomic arousal, would be the best fit for this work.
Not a fit: People whose reflux is driven purely by anatomic problems needing surgery or who do not have symptom-linked hypervigilance or autonomic arousal are less likely to benefit.
Why it matters
Potential benefit: If successful, this approach could ease reflux symptoms and improve daily function by treating the brain–body drivers of symptoms rather than relying only on acid-suppressing drugs.
How similar studies have performed: Behavioral and brain–gut therapies have helped people with other functional gastrointestinal disorders, but applying these approaches specifically to GERD-related hypervigilance is relatively new.
