Is autism spectrum disorder linked to gut health?

Question

Hello doctor,

My son has been diagnosed with autism spectrum disorder. He is currently undergoing treatment and has joined therapy. Recently, his therapists suggested checking for issues with his gut microbiota through a stool test. Is this necessary? I thought autism was mainly a brain-related condition. Is there a connection between gut health and autism? Should we go ahead with the stool test? We are trying to manage everything as best as we can.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Some studies are showing a relationship between gut microbes and autism (a developmental disorder characterized by difficulties with social interaction, communication, and restricted or repetitive behaviors). Some gut microbes produce a specific type of chemical called propionic acid, which is more prevalent in autistic kids. Another reason to check the gut health is not for microbes, but another problem with the intestines, which an autistic child is more prone to, is inflammatory bowel disease (a group of inflammatory conditions of the colon and small intestine, including Crohn's disease and ulcerative colitis). For these reasons, it is advisable to check for gut health.

A stool test is a non-invasive test and there is no problem in doing it as a basic investigation. If it is normal, nothing extra is required. So what has been suggested is correct and do it. Managing an autistic child is a tough job and I am impressed you are doing your best to manage it.

I hope I have answered your question.

Let me know if I can assist you further.

Regards.
