The microbiome can have a significant effect on gut function as well as on mood and behavior. The studies that have sought to evaluate the gut microbiome in ASD have demonstrated variable results. This is likely because there are many factors that impact the microbiome that may differ, on an individual basis, in patients with ASD. These factors include diet, geography, genetics, body mass index (BMI), medications and other medical conditions.
