Small Intestinal Bacterial Overgrowth (SIBO) test

What is small intestinal bacterial overgrowth (SIBO)?

It is normal to have bacteria in your large intestine, as it helps with the digestion of food. However, if

you have too much bacteria in your small intestine, it can interfere with digestion. This is a condition

known as small intestinal bacterial overgrowth (SIBO). SIBO can cause a variety of symptoms, including:

• bloating • abdominal discomfort • gas (flatulence) • nausea (feeling sick) • diarrhea

You will be given the test to use at home. Be sure to follow the instructions provided

What is a breath test?

A breath test is a non-invasive and safe test used to investigate and diagnose intestinal conditions, such as SIBO.

How does a breath test work?

Bacteria that live in the small intestine produce gases called hydrogen and methane when they digest

sugar. These gases then travel from the small intestine to the lungs, where they are released. A breath

test works by measuring the amount of hydrogen and methane that you breathe out over a three-hour

period after drinking a mixture of lactulose (a non-digestible sugar) and water. A rapid rise in exhaled

hydrogen or methane may mean there is a bacterial overgrowth in your small intestine.

Why do I need a breath test?

A breath test will allow us to determine whether your symptoms are caused by SIBO. Your doctor will then be able to decide on the best treatment for you.
