Fructose intolerance is the inability to digest Fructose, a sugar found in fruit , due to an insufficiency of an enzyme called fructase. The undigested sugar is fermented by bacteria in the bowel and the production of gases can lead to digestive complaints, including abdominal bloating and cramps, flatulence, diarrhoea and nausea after eating dairy.
Fructose malabsorption can be assessed by a breath test. After an overnight fast, a fructose solution is consumed and any undigested fructose will be metabolised by bacteria, producing hydrogen and methane gases. These gases (hydrogen and methane) can be collected at timed intervals.
This tests consists of taking 4 breath samples over the course of 60 minutes.
