A study of bulking agents in elderly patients.Age Ageing. 1980 Nov; 9(4):267-71.AA
A study comparing the effects of bran and ispaghula in constipated elderly patients is described. Ispaghula and bran increased the wet and dry stool weight. There were no serious side-effects and no change in colonic pressures. The use of these bulking agents is shown to be better than the traditional use of laxatives in the elderly.
