TEST BACKGROUND
What is SIBO?
SMALL INTESTINE BACTERIAL OVERGROWTH 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. The breath test is a simple, non-invasive test. After a 24 hours preparatory diet, the lactulose (or glucose or fructose) test substrate is swallowed. Lactulose is not absorbed and therefore may act as a food source for bacteria, if present, in the small intestine.
The bacteria may ferment the lingering substances and produce hydrogen and/or methane. These gasses may then be diffused into the bloodstream and exhaled via the breath. Breath samples are collected every 20 minutes for 3 hours. All tests use machines from QuinTron, the original manufacturer of BreathTracker, to measure both hydrogen and methane in a single sample of breath (alveolar air). Extensive quality control, including carbon dioxide measurements to assure an acceptable alveolar air sample, comply with the highest standards of analytical excellence. Effects of SIBO SIBO causes damage to the absorptive surface of the small intestine – the ability of the body to absorb nutrients from food.
The absorptive surface of the small intestine is likened to a shaggy carpet, with finger-like protrusions called villi. The surface of the villi contain microvilli, which act as the interface of absorption—microvilli secrete enzymes called “brush border enzymes” which break starches into single molecules and proteins into single amino acids, so these can be absorbed.
