SIBO Breath Test

How The SIBO Test Works and How It Can Benefit You

The SIBO breath test is a simple, noninvasive test that you do in the comfort of your home. After a 24 hours preparatory diet, you consume a small amount of lactulose. (this is different to lactose)

Lactulose is not absorbed and therefore acts as a food source for bacteria, if present, in the small intestine. The bacteria ferment the lactulose and produce hydrogen and/or methane gas. These gases are exhaled via the breath.

Breath samples are collected every 20 minutes for 3 hours, anyone who can blow into a tube can do the test.
These samples are posted back to the pathology lab in the provided package and the results take about one week to be finalized.

Identifying which gases are present and in what concentration can help us to develop the best treatment plan for you to eliminate your digestion problems



The bacterial overgrowth of the small intestine  can inhibit nutrient absorption and lead to the following serious health problems:

  • Irritable Bowel Syndrome (IBS)

  • Unexplained abdominal symptoms

  • Gas and bloating

  • The inability to tolerate sweet or starchy foods, fibre, or friendly flora supplements

Once bacterial overgrowth has been detected, Dr. Mariem will prescribe a program involving diet, digestive support, probiotics and antimicrobials.
Successful eradication of SIBO has been shown to reduce bloating, gas, diarrhoea, and abdominal pain in patients more effectively than many other treatments for IBS.
