New research suggests that around one in five autistic children are affected by constipation, with links to increased hospital visits for digestive issues. The findings, published in a leading gastroenterology journal, highlight the wider health impact this condition can have on young people.

The study examined more than 20 million health records of children aged six to 17 over a nine-year period. It found that constipation was significantly more common among autistic children than their non-autistic peers, alongside higher rates of related issues such as faecal incontinence. Those affected were also more likely to attend emergency departments or require hospital care for abdominal problems.

Further analysis showed that autistic children experiencing constipation faced a much greater likelihood of additional complications. They were considerably more prone to abdominal pain and far more likely to need urgent medical attention or admission to hospital compared with those without constipation.

Although researchers noted some limitations, including potential inconsistencies in diagnosis records, the overall findings underline the importance of recognising gastrointestinal symptoms early. Constipation in autistic individuals may present differently, sometimes appearing through behavioural changes such as disrupted sleep or reduced appetite. The study calls for greater awareness and improved approaches to care, aiming to reduce avoidable hospital visits and better support affected children and their families.
