Normally, bacteria are found in the trillions in the large intestine, where they perform various symbiotic functions for the human body.

SIBO is a condition where bacterial overgrowth occurs in the absorptive area of the body the small intestine.

SIBO Symptoms can include :

Alternating constipation and diarrhoea
Abdominal cramping
Bloating and/or wind
Burping and Acid Reflux/GORD
Food sensitivities
Joint pain
Skin rashes
Iron and B12 deficiency
Respiratory symptoms such as asthma

So you may be asking yourself, “isn’t that what IBS is”?  Well SIBO , or Small Intestinal Bacterial Overgrowth, is used a a technical term to describe too much gut flora growing where it should not be.   So whilst its similar to IBS, its not exactly that same.  SIBO relates more to IBS-D than IBS in general and some studies have shown that many people suffering from IBS (78%) have some form of SIBO.  More research information can be found here.
