Key result
Heart rate variability biofeedback for functional gastrointestinal disorders showed significant symptom improvements in two of four included studies, suggesting at least 6 weeks of therapy is needed.
Why the study?
Heart rate variability biofeedback influences autonomic activity, but evidence of its effect had not yet been systematically assessed in functional gastrointestinal disorders.

Vagal withdrawal in FGID suggests biofeedback potential; leaves open clinical utility without randomized evidence.
Does heart rate variability biofeedback improve symptoms in patients with functional gastrointestinal disorders?
Heart rate variability biofeedback shows emerging but mixed evidence for improving symptoms in functional gastrointestinal disorders, likely requiring at least 6 weeks of intervention.
Fu et al. (2025) conducted a review in Functional Gastrointestinal Disorders (FGID) (n=4). Heart rate variability biofeedback (HRVB) was evaluated on Symptom improvements. Heart rate variability biofeedback for functional gastrointestinal disorders showed significant symptom improvements in two of four included studies, suggesting at least 6 weeks of therapy is needed.
