Dr. Ali Rezaie is a gastroenterologist and epidemiologist out of Los Angeles California who practices in and researches irritable bowel syndrome, motility disorders in patients with inflammatory bowel disease and does population-based data analysis. He runs the Rezaie Lab out of Cedars Sinai and has published over 60 research articles in peer-reviewed journals including Gastroenterology, American Journal of Gastroenterology, Digestive Diseases and Sciences and Canadian Journal of Gastroenterology. His works have been cited more than 4,000 times by other scientific journals. Dr. Rezaie serves as the associate editor of the Journal of Digestive Disease and Sciences. He also trained in my home province in both Calgary and Edmonton where I’ve worked – so I feel like we’re connected in that way!  

Dr. Ali Rezaie and I discuss:

  • What is small intestinal bacterial overgrowth (SIBO)?
  • The most common causes of SIBO
  • Phases of digestion
  • What tests are evidence-based for SIBO?
  • What are the benefits and limitations of small bowel cultures versus hydrogen and methane breath testing
  • How is SIBO diagnosed
  • Where science is going to diagnose SIBO
  • Is stool testing an appropriate test for SIBO?
  • How do you respond when someone says ‘SIBO isn’t a real diagnosis’
  • What are some current challenges with SIBO diagnosis and what research is needed?
  • Why we need biomarkers for subtypes of IBS
  • Current therapies to treat SIBO
  • How should someone struggling with digestive issues who maybe think they have SIBO get started
