What is SIBO?
How does SIBO affect you?
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.
Small intestine - absorbing nutrients from food
Causes of SIBO
- Post infectious: a case of gastroenteritis can often be the “heralding event” for the development of SIBO
- Overconsumption of simple carbohydrates
- Medications: proton pump inhibitors, morphine and other opiates, narcotics, possibly beta agonists and calcium channel blockers
- Stress: chronic stress can decrease stomach acid output (hypochlorhydria).
- Normal stomach acid levels are required to kill bacteria
- Stress also causes changes in the motility of the small intestines, causing a pooling and stagnation which allows for bacterial overgrowth
- Altered anatomy: malformation of the ileocecal valve, surgical intervention causing scarring and adhesions altering the normal anatomy of the small intestines
- Initial colonization of bad bacteria: caesarean birth, no breast feeding

The breath test is a simple, non-invasive test. After a 24-hour preparatory diet, the substrate (lactulose) is swallowed. This is not absorbed but act as a food source for bacteria in the small intestine.
The bacteria ferment the test substance and produce hydrogen and/or methane. These are diffused into the bloodstream and exhaled via the breath.
Breath samples are measured for hydrogen and methane to determine if there is small intestinal bacterial overgrowth (SIBO).
How to prepare for your breath test
One Month Prior:
You must wait at least one month after a colonoscopy, barium study, colonic, or taking antibiotics to perform the breath test. The only exception is if retesting after antibiotic treatment for SIBO.
One Week Prior:
Stop taking probiotics, probiotic foods (yogurt, kefir, etc.), and herbal antimicrobials at least one week before testing.
24 Hours Prior:
Stop taking laxatives and digestive aids (enzymes, hydrochloric acid, etc.) 24 hours before testing. Only take essential supplements and eat a simple diet of chicken (or fish) with white rice ONLY (no veg/fruit/nuts etc). *This creates a standardised macronutrient ratio for measuring fermentation in the breath.
12 Hours Prior:
You must fast for 12 hours before beginning the breath test sample collection. Only water is allowed during this time. Download the instruction guide below for details.
