Correct answer: B — Toddler's diarrhoea

Toddler's diarrhoea (chronic non-specific diarrhoea of childhood) is the most common cause of chronic diarrhoea in well-thriving toddlers. Undigested food in stools is typical. Excessive fruit juice intake (fructose and sorbitol) is a common exacerbating factor. Management is dietary modification: increasing fat and fibre, reducing juice intake.
