Is there a link between poor gut health and ADHD?

The link between gut health and neurological conditions such as ASD (Autistic spectrum disorder) and ADHD (Attention deficit hyperactivity disorder) is an area of active research. The gut and the brain are connected through a bidirectional communication pathway known as the gut-brain axis. Changes in the gut microbiota can influence brain function and behavior, and vice versa.

According to Dr Keni Ravish Rajiv, Senior Consultant - Neurology and Head of Epilepsy Services, Aster Whitefield Hospital, Bengaluru, an imbalance in the gut microbiota, known as dysbiosis, has been observed in individuals with ASD and ADHD. This dysbiosis may contribute to inflammation, altered neurotransmitter levels, and other factors implicated in these conditions. (Source: Freepik)

"Dysbiosis can lead to increased intestinal permeability (leaky gut), allowing harmful substances to enter the bloodstream and trigger systemic inflammation and immune responses that may affect the brain," he explained. (Source: Freepik)

He also mentioned that studies suggest probiotics, which contain beneficial bacteria, may help improve symptoms of ASD and ADHD by restoring gut microbial balance. (Source: Freepik)

These are dietary fibers that promote the growth of beneficial bacteria in the gut. Including probiotic and prebiotic-rich foods such as curd, yoghurt, miso, fermented foods as well as garlic, onions, bananas, and asparagus in the diet may support gut health (Source: Freepik)

Some individuals with ASD or ADHD may have food sensitivities or intolerances that exacerbate symptoms. Identifying and avoiding these trigger foods can help manage symptoms. (Source: Freepik)

Adopting a diet low in processed foods and high in fiber, fruits, vegetables, and lean proteins can promote a healthy gut microbiota. (Source: Freepik)
