A double-blind randomised study revealed that 84% of IBS patients exhibited bacterial overgrowth based on lactulose breath testing*
SIBO is caused by overgrowth of bacteria in the normally sterile environment of the small intestine. These bacteria cause symptoms such as bloating, constipation, abdominal pain, and diarrhoea.
Hydrogen breath testing is recognized by the American College of Gastroenterology as a non-invasive method of diagnosing SIBO. Bacterial infections of the small intestine can be easily assessed by testing for the presence of hydrogen and methane in exhaled air.
IBS is an extremely common digestive disorder with no known single cause.
SIBO causes hydrogen, methane and/or hydrogen sulphide gas in the small intestine.
These gases can cause the symptoms of IBS, but also damage the intestinal wall and interfere with the digestive process.
