Autism and Digestive Issues Linked in New Study
Children diagnosed with autism spectrum disorder (ASD) are at a significantly higher risk of experiencing debilitating gastrointestinal issues, according to research published today.
Researchers at the University of California, Davis, evaluated over 475 children – 322 with ASD and 153 neurotypical peers – tracking them for approximately a decade. The study, published in August in the journal Autism, revealed that autistic children were initially over 50 percent more likely to suffer from symptoms like bloating, constipation, and diarrhea. By the end of the study period, this risk increased to more than four times that of their neurotypical counterparts. Constipation was the most frequently reported digestive issue among autistic children. This finding is particularly important as gastrointestinal distress can significantly impact quality of life and exacerbate behavioral challenges in individuals with autism.
The research team utilized questionnaires completed by parents and caregivers, assessing the frequency of various gastrointestinal symptoms. They found that children with autism and more pronounced gastrointestinal issues also exhibited increased instances of social difficulties, repetitive behaviors, aggression, and sleep disturbances. “This is not about finding a single cause. It’s about recognizing the whole child,” said Dr. Christine Wu Nordahl, senior study author and principal investigator at the UC Davis MIND Institute. “Supporting gastrointestinal health is one important step toward improving overall quality of life for children with autism.” Restrictive diets, common among children with autism, may contribute to these issues by limiting essential nutrients like fiber, potentially leading to digestive discomfort.

Researchers noted that screening for gastrointestinal problems could help reduce disruptive behaviors in autistic children and provide insight into the root causes of behavioral issues when communication is challenging. The prevalence of autism is rising, with current estimates indicating that approximately one in 31 children in the US is diagnosed with the condition, a substantial increase from one in 150 in the early 2000s, according to the Centers for Disease Control and Prevention.
The team plans to continue research to assess the long-term presence and persistence of gastrointestinal symptoms in children with autism throughout their development.
