Autism Spectrum & the Gut

Exploring the gut-brain link in autism

Up to 70% of people with autism experience GI symptoms, and researchers are uncovering profound differences in gut microbiome composition. Microbiome therapies targeting autism are among the most closely watched trials in the field.

The Microbiome Connection

How Autism Spectrum & the Gut relates to gut health

Common Symptoms

  • GI symptoms (constipation, diarrhea)
  • Abdominal pain
  • Food selectivity and sensory sensitivities
  • Behavioral changes linked to GI discomfort

How the Microbiome is Involved

Multiple studies have found that children with autism have significantly altered gut microbiomes — including lower Prevotella, Coprococcus, and Unclassified Veillonellaceae. These bacteria help produce short-chain fatty acids that support brain function and reduce neuroinflammation. The gut-brain connection in autism is an active, fast-moving area of research with parent communities closely watching trial outcomes.
