Autistic children more prone to stomach issues, study finds
Quote:
Children with autism are far more likely to experience chronic digestive issues compared to their peers, a study has found.
Researchers at the University of California monitored children’s development for more than a decade and found that gastrointestinal symptoms in autistic children were more frequent, intense, and long-lasting.
The study, published in the journal Autism saw that autistic children were more at risk across every stage of development, and symptoms were more likely to persist across childhood, instead of resolving themselves.
Bibiana Restrepo, the lead author of the study, said: “The connection between autism and gut symptoms has not been fully understood. Parents often sense that their child is having digestive issues, but can’t tell what is causing them.
“Our research shows that these symptoms are common, persistent, and can affect many areas of a child’s daily life. By identifying and treating them, we may be able to improve both physical comfort and developmental outcomes.”
The study tracked 475 children, including 322 children with autism. Researchers followed their progress from the ages of 2 to 12-years-old, conducting evaluations and interviews with their families over that time. Both the frequency and persistence of gastrointestinal symptoms were recorded.
The researchers evaluated nine typical gastrointestinal symptoms, including constipation, diarrhoea, abdominal pain and bloating.
Autistic children were more likely to develop each symptom, with constipation being the most common, affecting around 32 per cent of autistic children, compared to 11 per cent of those without autism. Researchers said their findings validated what has long been observed by parents.
Previous research has suggested that dietary preferences lacking in nutrients and food selectivity, which is common in autistic children, may play a role in the increased risk of stomach problems.
Professor Christine Wu Nordahl, an author of the study, said: “When children are experiencing stomach pain or other gastrointestinal problems, it doesn’t just affect digestion. It can influence sleep, mood, and how they interact with the world around them.”
