Regarding fiber in abdominal distention, which statement is true?

• A. Fiber should be avoided in all cases
• B. Fiber may help promote regular bowel movements but can cause gas; provide extra water flushes
• C. Water flushes are unnecessary and harmful
• D. Fiber worsens distention

Answer: (B)

Fiber can help with abdominal distention when constipation is a factor by increasing stool bulk and promoting regular bowel movements, but it can also lead to gas and bloating as it’s fermented by gut bacteria. The best approach is to introduce fiber gradually and pair it with adequate fluid intake. Providing extra water with fiber supports its ability to move through the GI tract, helps soften stools, and reduces the risk that increased bulk will worsen distention. This nuance—balancing the potential benefit on transit with the possibility of gas, plus using hydration to optimize tolerance—makes this statement the most accurate. In cases of true obstruction or ileus, fiber may be avoided, but the general principle still holds: fiber can aid regularity and distention relief when hydration is ensured and introduction is gradual.
