Sorbitol Malabsorption Test



Sorbitol is often used as a sweetener in "diet" or "sugar free" foods and drinks. It can also occur naturally in foods such as pears, prunes, peaches, cherries, and plums. In large quantities, Sorbitol may cause osmotic diarrhoea, however in patients that suffer from IBS, lower amounts of Sorbitol can cause abdominal and GI symptoms.

The Hydrogen and Methane breath test is performed to test for sorbitol intolerance. This is a non-invasive test that is performed in the clinic.
