Abstract

Although malabsorption of small amounts of fructose-sorbitol mixtures occurs frequently in healthy humans, insights into their effects on gastrointestinal motility are poor. The present study addresses the hypothesis that malabsorption of a fructose-sorbitol challenge changes the small intestinal transit rate. Eleven healthy volunteers participated in a double-blind crossover investigation. In random order, the subjects ingested 30 g glucose or a mixture of 25 g fructose and 5 g sorbitol as 10% solutions. As a radiolabeled marker, (99m)Tc-diethylenetriaminepentaacetic acid was added to each test solution. Breath hydrogen and methane concentrations and gastrointestinal progress of the radiolabeled marker were followed for the next 6-hr period. Malabsorption of small amounts of the fructose-sorbitol mixture was evident in all subjects. The area under the gastric radioactivity-time curve after ingestion of glucose did not differ from that after ingestion of the fructose-sorbitol mixture (P = 0.7897). However, the mouth-to-cecum transit of the radiolabeled marker was faster (P = 0.0033) and the percentage content of the marker in colon was higher after ingestion of the fructose-sorbitol mixture than after ingestion of glucose (P = 0.0128). In healthy humans, malabsorption of small amounts of a fructose-sorbitol mixture accelerates small bowel transit.
