What is SIBO?

Have you considered small intestine bacteria overgrowth (SIBO) as a possible explanation for your digestive discomfort? The latest research is showing that up to 80% of people with IBS, have SIBO!

Under normal circumstances, most of our gut bacteria live in our large intestine and our small intestine is relatively sterile. But bacteria can also increase in numbers in our small intestine and small intestine bacteria overgrowth (SIBO) develops.

SIBO testing may also help people with Crohn’s disease, celiac disease, or scleroderma experiencing continued or worsening symptoms despite adequate treatment.

Hydrogen and methane are produced by the digestive system primarily by the bacterial fermentation of carbohydrates, and so when these gases appear in exhaled air, we can assume that the carbohydrates have been processed by bacteria.

When we eat carbohydrates, they enter the small intestine before the large intestine. By looking at when gases are produced by the bacteria, we can determine if there is an overgrowth of bacteria in the small intestine.

Excessive hydrogen is generally associated with diarrhea

Excessive methane is normaly associated with constipation
