What is SIBO

Small Intestinal Bacterial Overgrowth - SIBO - is a medically recognised disorder of the gut that involves harmful bacteria migrating from the colon to areas of the intestinal tract where it should not be.

Our gut operates with beneficial bacteria that help with a multitude of functions in the human body, this is called the gut microbiome. This gut microbiome is now scientifically recognised as its own multitasking organ that is vital in maintaining human health. The average healthy gut biome has millions of bacteria per millilitre of fluid. Different species of these bacteria live in different areas of the digestive tract (the stomach for example holds different bacteria to the colon).

With our lifestyle, diet and medicines we consume today, we have greater risk of this delicate balance of gut flora to become imbalanced. Typical causes of gut microbiome imbalance are:

Medicines – antibiotics, steroids, hormones

Weakened immune system – stress, not enough exercise, not enough sleep

Diet – sugar, processed foods, fast food, non organic food

Alcohol consumption

All of the above lead to problems with the delicate balance of bacteria spread throughout the digestive tract. SIBO (small intestinal bacteria overgrowth) is specific to the colonies and bacteria types of the colon. These bacteria have a specific function necessary for the body but problems occur when these bacteria bloom and spread upwards into the small intestines.


This population of various colon bacteria in the small intestines cause serious issues as the purpose of these bacteria is to breakdown nutrients. When this happens outside of the colon it causes many unpleasant symptoms and can lead to serious health issues and complications
