I was diagnosed with LPR by an ENT doctor. Treated by ENT who prescribed ppi’s which made the LPR worse. Went to internal medicine doctor who tested (breath test) for SIBO….and unfortunately I tested positive for SIBO. Before you go down the LPR path, ( wasting time and money) get tested for SIBO. The treatments are vastly different. Wish someone had told to get the SIBO test. Good luck to you!
