To complete this test, you would drink a special sugar mixture that acts as food for these bacterial colonies. You take a breath sample every 20 minutes over a 3 hour period as this mixture moves through the small intestine. The bacteria can produce a mixture of hydrogen and methane gas as it feeds on the mixture. By sampling the amount of gas produced, we can determine whether there is a bacterial overgrowth present.
