What It Is
Common GI issues in autism include constipation, diarrhea, irritable bowel syndrome, reflux, abdominal pain, and nausea. The causes are not yet well understood.
How It Presents in Autistic People
GI pain in autistic people may present as increased irritability, aggression, meltdowns, sleep disruption, or behavioral changes rather than direct reports of stomach pain, particularly in nonspeaking people. Identifying GI issues as a contributing factor to behavioral changes is essential.
Treatment and Support
Dietary assessment (including ARFID evaluation), gastroenterology referral, and treatment of specific GI conditions is appropriate. Addressing sensory-based food restriction may improve nutritional status.
