Lactose intolerance is the inability to digest lactose, a sugar found in milk and other dairy products, due to an insufficiency of an enzyme called lactase. 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.
Lactose malabsorption can be assessed by a breath test. After an overnight fast, a lactose solution is consumed and any undigested lactose 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.
