  • 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).


Inclusion Criteria: - age ≥18 years - living in the community (not a nursing home or assisted living facility) - self-report of usually having FI of loose or liquid consistency at least twice in a 2-wk period - toilets independently - ability to read and write in English. - Persons that regularly performed pelvic floor muscle exercises and/or biofeedback on a maintenance regimen for at least 20 wks or who took a steady dose of anti-motility medications on a regular schedule that still met the FI criteria were also eligible. Exclusion Criteria: - difficulty swallowing, - a gastrointestinal (GI) tract altered by surgery, - a malabsorption disorder, - inflammatory bowel disease, - gastrointestinal cancer or active cancer treatment, - allergy to the fibers, - regularly used a laxative or enema, were tube-fed, or unwilling to discontinue taking periodic self-prescribed fiber supplements or anti-diarrheal medications. - a score ≤24 on the Mini Mental State Examination - having/reporting fewer than two episodes of FI or being incapable of performing study procedures during the run-in baseline period
