The risk of malnutrition in children with autism spectrum disorder.

A 9-year-old boy presented with a 2-day history of vomiting, ataxia and reduced consciousness. He had vomited intermittently in the two preceding months, without headaches, visual disturbance or early morning symptoms. He had autism spectrum disorder, and restricted eating since aged 2 years, eating only corn-crisps, Rich Tea biscuits and chips (French fries), and drinking Coca-Cola (containing 10% glucose; figure 1). Recently a dietician had prescribed a multivitamin.
