• The Bile Acid Imbalance Accelerating Aging: How to Detect ​& Fix It

  Have you ever struggled to understand why some patients just don’t respond as expected, even when you’re following all the usual gut protocols? In this episode, I sat down with Dr. Tom Fabian, who breaks down the latest insights from StoolOMX and GI-MAP testing and shows us how to put them into practice for our most complex cases. We dive into how identifying specific types of inflammation, bile acid patterns, and microbial imbalances can guide more precise interventions, whether it’s introducing fiber, addressing biofilms, or supporting secondary bile acid production. Dr. Fabian makes the science practical, helping us see not just what’s happening in the gut, but what to do about it in real-world clinical settings. ~DrKF FOLLOW ALONG WITH THE CONVERSATION!
