The Sorbitol Intolerance Test consists of ingesting a solution containing this sweetener, followed by collecting breath samples every 30 minutes for 3 and a half hours (210 minutes in total).
Under normal conditions, sorbitol is absorbed in the small intestine. When this does not happen, it passes to the colon, where it is fermented by intestinal bacteria that produce gases such as hydrogen and methane. These gases enter the bloodstream and are eliminated through exhaled air, allowing them to be detected with a breath test.
Thanks to this test, it is possible to confirm if sorbitol malabsorption is the cause of your digestive discomfort and guide a personalized dietary treatment.
