Correct answer: E — Toddler's diarrhoea (functional diarrhoea)

Toddler's diarrhoea (chronic nonspecific diarrhoea) is the most common cause of chronic diarrhoea in well-thriving toddlers. Stools are loose and may contain undigested food. Growth is normal. It is a functional GI disorder (Rome IV). Dietary normalisation (adequate fat, moderate fibre, reduced juice) is the main intervention.
