Gastrointestinal symptoms are not linked to later autism

Children with autism are no more likely than children without autism to have had a defined gastrointestinal disorder at any time before autism is diagnosed. In a case-control study by Black and colleagues (p 419), 96 cases of autism were identified from the UK general practice research database between 1988 and 1999. Each was matched with up to five controls. A history of chronic gastrointestinal inflammation, coeliac disease, food intolerance, or recurrent gastrointestinal symptoms was not more common in children with autism than in those without autism.
