Irritable bowel syndrome (IBS) impacts more than 45 million Americans and about 1 in 10 globally. So, if you have abdominal pain, diarrhea and/or constipation on a regular basis...you are not alone. We are thrilled to have world-renowned gastroenterologist, Dr. William Chey, on this episode to discuss this diagnosis along with common IBS mimickers.  Dr. Chey is the Chief of Gastroenterology at the University of Michigan and a true physician champion for the importance of a multidisciplinary approach to the management of IBS. He discusses how this complex condition, once perceived purely as a psychosomatic disorder, has evolved into a multifaceted syndrome with new and improved treatment methods. Discover the transformative potential of dietary strategies like the low FODMAP diet, the integration of behavioral therapy along with complementary and alternative medicine (like acupuncture) into patient care, as we explore the nuances of treating IBS and its masqueraders. Dr. Chey sheds light on the enlightening findings from a recent study on disaccharidase deficiencies, particularly the surprising prevalence of sucrase-isomaltase deficiency in IBS patients with diarrhea predominance. Gain insight into the challenges of current testing methods and the role of bile acid malabsorption, which opens the door to a more precise and personalized approach to managing unruly gut symptoms. The conversation steers toward the promise and limitations of breath tests and the significance of a Dream Team approach, blending expertise from various specialists to address the unique needs of each patient. We also delve into the intricate relationship between small intestinal bacterial overgrowth (SIBO) and bile acid diarrhea, and the innovative work of researchers like Dr. Mark Pimentel. Dr. Chey emphasizes the growing importance of precision medicine in the field of gastroenterology and gut health, highlighting the complexities of diagnosing and treating conditions such as SIBO.
