Bloating has become so common that most people assume it's just a normal part of life. But chronic, daily bloating is not something you simply have to accept — and in many cases, it points to a specific, treatable condition called Small Intestinal Bacterial Overgrowth, or SIBO.

In this episode of the Science of Self-Healing, we dig into the science behind SIBO — what it is, why it develops, and why it so often goes undiagnosed for years. We explore how the digestive system's natural defense mechanisms, including stomach acid, the migrating motor complex, and gut immunity, are designed to prevent bacterial overgrowth, and what happens when those systems break down.

We also discuss the different types of SIBO, its surprising overlap with IBS, the connection between thyroid health and gut bacteria, and why diet alone rarely provides lasting relief. Finally, we walk through the evidence-based 4R Protocol — Remove, Replace, Reinoculate, and Repair — a structured, natural approach to healing the gut and restoring microbial balance.

If you have been living with unexplained bloating, fatigue, brain fog, or digestive irregularity, this episode may offer the missing piece you have been looking for.
