Which of the following is a possible complication of dietary fiber-containing enteral formulas?

• A. Altered absorption of minerals
• B. Increased potency of medications
• C. Fluid retention
• D. Bloating and flatulence

Answer: (D)

The main concept here is that fiber-containing enteral formulas can commonly cause gas-related GI side effects. Fiber isn’t fully digested in the small intestine, so it travels to the colon where gut bacteria ferment it. This fermentation produces gases and short-chain fatty acids, which often lead to bloating, abdominal distention, and flatulence, especially when starting the formula or adding more fiber. That makes bloating and flatulence the most likely complication.

While some fibers can influence mineral absorption by binding minerals, that’s a less immediate or universal issue with these formulas. Increased medication potency isn’t a typical consequence, and fluid retention isn’t associated with dietary fiber in enteral products.
