Hydrogen Breath Test
To test if you are lactose or fructose intolerant, your clinician will order a Hydrogen Breath Test. This is a simple test where you breathe into a handheld device. Your breath is analysed and shows how you digest lactose, (milk sugar) or fructose (fruit sugar). The test is based on the fact that intestinal bacteria in the gut produces hydrogen gas, normally in the large intestine, by fermenting carbohydrates such as the sugars fructose, lactose and others.The bacteria can be detected in the breath, since some of the hydrogen it produces is absorbed by the mucosa in the intestines and then into the bloodstream and is carried to the lungs. The small intestine usually breaks the sugars down so they don’t get to the large intestine. However, many adults cannot absorb the sugars in the small intestine so they go to the colon where they produce a large amount of hydrogen that can be measured during the breath test.
Are You At Risk?
If you need a Hydrogen Breath Test to check for lactose or fructose intolerance you need to take the following steps:
Be aware that the Hydrogen Breath Test can take from two to three hours and is a very safe test with no side effects other than possibly reproducing some of your symptoms for a little while.
