title: Effect of psyllium hydrophilic mucilloid on oral glucose tolerance and breath hydrogen in postgastrectomy patients.
abstract: Twenty postgastrectomy patients ingested glucose solutions with or without psyllium hydrophilic mucilloid to determine its effects on their blood glucose and breath hydrogen excretion. On the basis of the breath hydrogen tests following glucose alone, 15 had various degrees of glucose malabsorption which the addition of psyllium markedly reduced. In all 20 patients, psyllium significantly lowered peak blood glucose and prolonged its rate of fall. However, areas under the glucose concentration time curves were similar with and without psyllium, suggesting that total glucose absorption was unaltered by psyllium. In vitro, centrifuged psyllium-water-glucose slurries released glucose over 3 hr into water. Although the mechanisms of the psyllium alteration of the blood glucose and breath hydrogen responses are probably multifactorial, our studies suggest that release from the psyllium-glucose slurry results in a slower and more complete glucose absorption.
