Which statement is NOT listed as a contributing factor to constipation?

• A. High fiber intake
• B. Unhealthy dietary and bowel habits
• C. Lack of exercise
• D. Delays intestinal motility or obstruction present

Answer: (A)

High fiber intake is protective against constipation because it adds bulk to stool and helps water stay in the stool, which speeds up transit through the colon and makes bowel movements easier. That means it is not a factor that contributes to constipation; rather, it helps prevent it. The other statements describe situations that can slow or hinder stool passage—unhealthy dietary and bowel habits can reduce transit, lack of exercise can lower colonic motility, and any condition that delays motility or presents an obstruction can directly cause constipation. So the statement about high fiber intake is the one that is NOT a contributing factor.
