The Impact of Fiber Fermentation on Fecal Incontinence
The primary aim of this study was to compare the effects of supplementation with one of
three dietary fibers (gum arabic, carboxy-methylcellulose, or psyllium) or a placebo on
fecal incontinence (FI), symptom intolerance, and quality of life in community-living
individuals who have incontinence of loose or liquid feces. A secondary aim was to explore
the possible mechanism(s) underlying the supplements' efficacy (i.e., improvements in stool
consistency, water-holding capacity or gel formation).
