Children’s GI problems appear less likely to respond to autism treatment and therefore GI symptoms may need to be considered and treated when creating a treatment plan for a child with autism.

The purpose of this study was to study the GI problems in a large sample of children with autism. The authors studied 172 children who entered two large-scale autism drug therapy trials. The groups (GI problems and no GI problems) were the same with regards to sex, race, special education placement, and family background. It seemed that those children who had more GI problems also had more behavioral problems. Children with autism and GI problems also had more social problems than children without GI problems.
