I am new to this site but a 20+ or more years sufferer. Has anyone any experience/results of a small intestine bacterial overgrowth (SIBO) breath test. First heard about it on TVs Dr Chatterjee Doctor in the House programme. Seen an NHS gastroenterologist this week and now waiting for the test kit to arrive. My GP had never heard if it. Just wondered if anyone out there had any experience. Thanks for reading.
