SIBO: A Root Cause of IBS? with Dr Steven Sandberg-Lewis

Each of us is home to trillions of microbial hitchhikers and which have a profound influence on our health and wellbeing.

Small intestinal bacterial overgrowth (SIBO) is a disruption in our normal gut ecology whereby there is an increase of bacteria and/or changes in the types of bacteria present in the small intestine.

According to Prof Steven Sandberg-Lewis, a leading naturopathic expert on gastrointestinal disease and a pioneer in the field of SIBO, the condition is the root cause for 50-75% of all cases of irritable bowel syndrome (IBS). In today’s podcast, Prof Sandberg-Lewis takes us through the interrelationship of SIBO with irritable bowel syndrome (IBS) and how to define and rule out one from the other.
