Fructose-Sorbitol Malabsorption Test



Fructose and Sorbitol are quite often found together in fruit or added to processed foods. Some people have trouble absorbing these sugars properly when they are consumed at the same time. This can lead to symptoms such as bloating, cramps, diarrhoea/constipation, gas, nausea, or wind.

Testing is non-invasive. Hydrogen and methane gas measurements are analysed from breath samples taken at regular intervals following the ingestion of a testing solution. This test is only available in the clinic.
