Abstract Some research suggests that GI symptoms seen in children with ASD may relate to behavior problems. The objective of this pilot study was to assess the effect of the low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet on GI and behavioral problems in children with ASD. At follow-up, the low FODMAP diet group had significant relief in some GI problems compared with both baseline in the group and control group. At baseline and at follow-up, there were no significant differences in behavioral problems between the low FODMAP diet group and the control group. Randomized controlled studies including larger sample sizes are needed to confirm the effects of low FODMAP diets in children with autism who have gastrointestinal problems.

Introduction Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by difficulty with social interaction and communication and the presence of limited interests and repetitive behaviors typically seen before 3 years of age (Tuohy et al. 2015). The prevalence of ASD in the United States in 2014 was 1 in 59 among children aged 8 years (Baio et al. 2018).

gastrointestinal (GI) symptoms including chronic constipation, diarrhea, abdominal pain, abdominal distention, gastroesophageal reflux, and vomiting (Reddy and Saier 2015). The most common GI disorder reported for children with ASD is functional constipation (85%), which has been correlated with speech disorders (Gorrindo et al. 2012). Deficiency in verbal communication or lack of communication of children with ASD causes difficulties in recognizing underlying causes of GI conditions and other medical problems. Pain, 3
