Gastrointestinal Issues

Also known as: GI issues

What does Gastrointestinal Issues mean?

Gastrointestinal issues refer to problems with the digestive system, such as constipation, diarrhea, stomach pain, reflux, nausea, bloating, or difficulty tolerating certain foods. These concerns are reported more frequently in autistic children than in the general population, though the reasons for this connection are still being studied. Because some autistic children may have difficulty communicating physical discomfort, gastrointestinal issues can sometimes show up as changes in behaviour, mood, or sleep.

Why this term matters

Unrecognized or untreated gastrointestinal discomfort can affect a child's ability to focus, participate, and feel comfortable at school and at home. Identifying and addressing these physical concerns can make a meaningful difference in a child's overall quality of life and may also help explain some behaviours that were previously puzzling.

Canadian context

A family doctor or paediatrician is typically the starting point for addressing gastrointestinal concerns in Canada, and referrals to a paediatric gastroenterologist may be available depending on the province or territory. Wait times and access to specialists can vary considerably by region, so families may find it helpful to speak with their primary care provider about next steps as early as possible.
