Lactulose, unlike glucose, is not absorbed in your system. It is a sugar not digested by the body, meaning that it is able to travel all the way through the small intestine without modification in normal physiology. The lactulose breath test thus allows detection of abnormally increased numbers of bacteria located in the distal small intestine. It acts as a food source for bacteria, if present in the small intestine. If bacteria are present, lactulose will allow the bacteria to ferment, producing hydrogen (H2) and/or methane (CH4). These gases are diffused into the bloodstream and exhaled by the breath.  

With lactulose testing, breath samples are collected every 20 minutes over the course of 3 hours.

SIBO CLINIC CANADA uses the gold standard Quintron BreathTracker for analyzing the breath samples that are returned to our facility.  We use extensive quality control, which includes carbon dioxide measurements, to ensure an acceptable air sample.  We comply with the highest standards of excellence.


Anyone suffering from symptoms of stomach distension, bloating, gas, diarrhea/constipation, indigestion and IBS can benefit from this testing. Consider this breath test the first step to understanding your condition and treatment options.


SIBO can be debilitating. If you suffer from any of the above symptoms, chances are it is greatly affecting your daily life. Left unchecked, SIBO can lead to any of the following:

Alzheimer’s, Parkinson’s, Multiple Sclerosis, Acid reflux, Fibromyalgia, Chronic Fatigue Syndrome, Inflammatory diseases, Irritable Bowel Syndrome, Type 2 Diabetes, High Blood Pressure, Brain Fog, Autoimmune Disease, Leaky Gut, Acne, Restless Leg Syndrome, Weigh loss/Weight gain and many other conditions. 


Dietary carbohydrates, unabsorbed in the small intestine, are fermented in the large intestine by bacteria, resulting in the production of hydrogen and/or methane gases.

In patients with SIBO, bacterial fermentation of these carbohydrates occurs in the small intestine, producing gas which then gets absorbed into the bloodstream and exhaled in the breath.
