IBS is complicated, and while we wish it were possible to absorb everything during a 15-minute visit with a gastroenterologist, that isn't realistic. This is a comprehensive course for people diagnosed with irritable bowel syndrome — the material your GI team would walk you through if they had unlimited time in the room.
Fifteen lessons, taught by board-certified GI physicians, a GI dietitian, and a GI psychologist from Harvard, Stanford, UCLA, and Washington University in St. Louis. Built on ACG, AGA, and NICE guidelines and the Rome Foundation diagnostic criteria.
You'll come away with an understanding of the brain-gut biology behind your symptoms and clarity on what your diagnosis actually means, including how the Rome criteria distinguish IBS-C, IBS-D, IBS-M, and IBS-U, how the subtype changes the treatment, and what your GI is ruling out along the way: celiac disease, non-celiac gluten sensitivity, bile acid malabsorption, inflammatory bowel disease, microscopic colitis, endometriosis, carbohydrate intolerances, sucrase-isomaltase deficiency, exocrine pancreatic insufficiency, thyroid disease, and SIBO/IMO.
Then the course turns to what you can actually do about it. A rigorous walk through the low FODMAP diet, and when it isn't the right first move. The evidence base, and the honest limits, of soluble fiber, peppermint oil, digestive enzymes, and probiotics. A full lesson on medications and how gastroenterologists sequence OTC and prescription options by subtype, including linaclotide, rifaximin, and neuromodulators at IBS-specific doses. And the brain-gut behavioral therapies, such as GI-focused CBT and gut-directed hypnotherapy, that most patients are never told about.
Six "In the Office" interviews go deeper on questions where clinical opinion still splits — like SIBO breath testing and microbiome testing — plus the IBS/endometriosis overlap, pelvic floor dysfunction, and red flags for escalating care.
We highlight where the right answer depends on your specific subtype, triggers, and medical history, because IBS management isn't one-size-fits-all. Every lesson pairs video with written content, evidence-cited charts, and clinical decision tables. The goal: give you the foundation to make treatment decisions with your care team, not around them.
