The occurrence of dumping symptoms during 1 wk of use of 5 g of guar gum or placebo in meals was examined in a double-blind study in 11 patients, who had undergone gastric resection and were suffering from the dumping syndrome. The results show that guar gum prevented the dumping syndrome and increased tolerance to foods not previously tolerated in nine of the 11 patients.
