Which of the following is NOT a contributor to constipation in enterally fed patients?

• A. Fluid restriction
• B. Physical inactivity
• C. Narcotic usage
• D. High-fiber diet

Answer: (D)

Constipation in patients receiving enteral nutrition is driven by low stool water, decreased gut motility, and medications that slow the bowel. When fluid intake or absorption is restricted, the stool becomes drier and moves more slowly, increasing constipation risk. Physical inactivity also lowers the frequency and strength of bowel movements, reducing transit. Narcotics slow intestinal contractions and secretions, leading to harder stools and longer transit time.

A high-fiber diet, on the other hand, generally helps prevent constipation by increasing stool bulk and stimulating peristalsis. In most enteral feeding scenarios, fiber-rich formulas or fiber supplements are used to improve bowel regularity, though certain clinical conditions may require low-fiber options. So, the nutrient pattern that does not contribute to constipation is a high-fiber diet.
