A new study from the UC Davis MIND Institute found that autistic children are much more likely to struggle with stomach and digestive problems than children who are not on the spectrum. These are referred to as gastrointestinal (GI) problems. The study also showed that these stomach issues can be linked to more significant challenges, such as sleep disturbances, behavioral issues, and communication difficulties.
Researchers followed 475 children aged 2 to 12. Out of these, 322 were on the autism spectrum and 153 were developing typically. Families participated in detailed interviews with doctors several times during the study, which helped track the frequency and duration of stomach issues over the years.
What the Study Found
The researchers learned that autistic children were not just more likely to have digestive problems—they were also more likely to have several symptoms at once, and those problems tended to stick around for years instead of going away quickly.
Some common symptoms studied were:
While occasional stomach issues arise for many kids, Autistic children had more problems at every age studied. Approximately 30% of the autistic children reported stomach issues at each check-in, while the majority of non-autistic children reported limited GI problems or none at all.
The stomach problems affected more than digestion; children with increased stomach issues were also more prone to:
This connection between the mind and body is demonstrated here. When a child experiences stomach pains, it can also affect their mood, sleep, and perception of the world.
Why It Matters for Families
The researchers explained that even if doctors don’t always find an apparent medical reason for these stomach issues, the symptoms are real and should not be dismissed. Many gut-related problems are treatable, and getting help can improve a child’s comfort.
For parents, this is a relief because it confirms what many families have been concerned about regarding their children’s gut issues. Doctors, teachers, and caregivers should discuss these issues more openly during regular check-ups and care plans.
The researchers hope that this study will encourage more collaboration between pediatricians, gastroenterologists, and autism experts.
As one of the study authors said, “This is not about finding a single cause. It’s about recognizing the whole child. Supporting gastrointestinal health is one important step toward improving overall quality of life for autistic children.”
Supporting Families Beyond the Study
This study is one of the largest and longest to track stomach issues in autistic children, and it makes one thing clear: caring for children on the spectrum means looking at both their mind and body. Every child deserves comfort, support, and a chance to thrive. If your family is facing challenges with autism, such as school struggles and speech-related problems, you don’t have to carry it alone.
