Enteral fiber is commonly associated with which outcome regarding diarrhea?

• A. Improvement in diarrhea
• B. Worsening of diarrhea
• C. No change in diarrhea
• D. Increased diarrhea severity

Answer: (A)

Introducing soluble dietary fiber through enteral nutrition commonly improves diarrhea. Soluble fiber forms a gel-like substance that binds water, slows intestinal transit, and increases stool bulk, which helps convert loose stools into more formed ones and reduces stool frequency. Fermentation of soluble fiber also produces short-chain fatty acids that nourish the colon and support absorption, further stabilizing stool output. Insoluble fiber can be less beneficial or even problematic in some patients, so the emphasis is typically on soluble fiber and gradual titration with monitoring for tolerance.
