Cutting-Edge Metabolomic Testing for IBS, Longevity, and Metabolic Health

We’re witnessing an exciting shift in how we understand gut health and disease—and it’s all thanks to the powerful metabolites produced by the microbiome, like short-chain fatty acids (SCFAs) and secondary bile acids. In today’s episode, Dr. Tom Fabian shares groundbreaking insights into how these postbiotics influence intestinal barrier integrity, immune balance, and even muscle regeneration. These compounds are also connected to key processes like glucose metabolism and healthy aging. What’s truly fascinating is how this science is opening up new frontiers in treating IBS, metabolic conditions, and chronic gut issues. With the upcoming launch of Diagnostic Solution Laboratories’ StoolOMX test, an add-on to the GI-MAP, we now have a tool to measure these metabolites in clinical practice, making personalized and effective treatments more attainable. This is a pivotal moment in functional medicine that you don’t want to miss. ~DrKF
