What concern may arise if a low-residue diet is given for long without review?

Correct answer: Fibre and some micronutrients may be low

A low-residue diet restricts foods that contribute substantial stool bulk, often including many whole grains, raw vegetables, fruit skins, seeds, and some pulses. If continued longer than clinically necessary without review, total fibre, vitamin, mineral, and sometimes energy intake may become inadequate. The diet should have a clear indication, appropriate duration, sufficient fluids when allowed, and professional reassessment before liberalization or continuation.
