Of course “The Gut Health Protocol” covers SIBO in-depth. But sometimes people just want to know “what is SIBO”. So you can now download the first 4 pages of Chapter 5, “Small Intestinal Bacterial Overgrowth”. This covers the basics and gives you a feel for the book. The remainder of Chapter 5 provides more depth, many more studies, treatment options, and explains the various medical tests for SIBO.
