Abstract
Supplements consisting primarily of dietary fibers are marketed as aids to weight reduction. Of uncertain efficacy, they have generally been regarded as safe when used according to directions. We report two cases of acute esophageal obstruction by a guar gum product in patients with preexisting esophageal abnormalities and review similar reports from other centers.
