It's great you're looking into the gut-brain connection! Research shows a clear link between gut health and autism symptoms. Studies have found that imbalances in gut bacteria can affect brain function and behavior in autistic children [1, 2].

Here's what you can do: First, pay close attention to any GI issues your child might have, like constipation or reflux, as these can worsen behaviors [6]. Next, prioritize a balanced diet with plenty of nutrients. Some studies suggest that improving gut health through interventions like probiotics or prebiotics might be helpful, so it's worth discussing with your doctor [1, 6].
