How is this national list of irritable bowel syndrome specialists built?
This page includes physicians in Convene Health's public directory whose profile lists Irritable Bowel Syndrome as a clinical focus area, ranked by composite score (research output, peer recognition, frequency of care, and outcomes signals). Each profile is sourced from the NPI registry, peer-reviewed publication data, board certification records, and the physician's own bio where available.
What should I look for when choosing a irritable bowel syndrome specialist?

Are these irritable bowel syndrome specialists accepting new patients?
Profile detail on availability and accepted insurance varies. Open a specific provider profile to see what they've published about new-patient access, insurance accepted, and typical wait times. Coverage details can change — confirm directly with the practice before your visit.
