  • IBS is an extremely common digestive disorder with no known single cause.
  • 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.  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. 
  • 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.
