Gut Issues in Children with Autism: Understanding the second brain

In recent years, there has been a growing acknowledgment of the intricate relationship between gut health and neurodevelopmental disorders, particularly in children with autism spectrum disorder (ASD). The gut-brain connection is a complex interplay that defines the development of children with Autism.

Read on to understand the common health issues associated with gut health in children with autism and explore strategies to address these concerns. Also read about why the Homeopathic holistic approach is the safe and sure way to make improvements in gut health.


The Gut-Brain Axis and Autism

The gut-brain axis refers to the bidirectional communication network between the central nervous system and the gastrointestinal tract. Emerging research suggests that disruptions in this axis may contribute to the manifestation of symptoms in children with autism. Individuals with ASD often experience gastrointestinal (GI) issues at a higher rate than their neurotypical peers. Common gut health issues in this population include:


Dysbiosis: Imbalance in the gut microbiota, with an overgrowth of harmful bacteria and a decrease in beneficial bacteria, can lead to dysbiosis. This imbalance is frequently observed in children with autism.


Leaky Gut Syndrome: Increased intestinal permeability, commonly known as leaky gut, allows for the passage of toxins and undigested food particles into the bloodstream. This can trigger immune responses and inflammation, potentially exacerbating autistic symptoms.


Constipation and Diarrhea: Children with autism often experience disruptions in bowel movements, ranging from chronic constipation to bouts of diarrhea. These issues may be linked to alterations in gut motility.


Food acceptance- While low food acceptance is considered a sensory issue in children with ASD, it can be directly connected to gut health. Alteration of taste can occur due to abnormal digestion, directly effecting food acceptance. Improving gut health can lead to better appetite and better food acceptance.


Gastrointestinal Discomfort and Pain:

Children with autism often experience gastrointestinal discomfort, such as constipation or diarrhea. Communication challenges may make it difficult for them to express this discomfort verbally. In response to pain or discomfort, behavioral changes may occur, including increased irritability, restlessness, or self-stimulatory behaviors.


Enteric Nervous System: The second Brain

Often referred to as the "second brain," the enteric nervous system in the gut can influence emotional and behavioral responses. Abnormalities in this system, which have been observed in individuals with autism, may contribute to both gastrointestinal and behavioral issues.


Food Sensitivities: Sensitivities to certain foods can contribute to GI discomfort and exacerbate behavioral symptoms associated with autism. Identifying and managing these sensitivities is crucial for overall well-being.


Addressing Gut Health Issues in Children with Autism


Specialized Diets:

  • While there are a lot of specialised diets recommended for children with Autism, these cannot be generalised, and do not give effective results in all children. A popular belief of reducing behavior and GI symptoms by eliminating gluten and casein from the child's diet, may not work in all children. However, individualised diet plans are more effective based on the individual child and their food acceptance, their gut composition and behavioural issues.

Probiotics and Prebiotics:

  • Introducing probiotics and prebiotics can help restore a healthy balance of gut bacteria. Probiotics are beneficial live bacteria, while prebiotics are substances that nourish the existing beneficial bacteria. These need to be prescribed based on the child's needs.

Nutrient-Rich Diet:

  • Ensuring a well-balanced, nutrient-rich diet can support overall health. Incorporating a variety of fruits, vegetables, lean proteins, and whole grains provides essential vitamins and minerals crucial for both physical and cognitive development.

Individualized Treatment Plans:

  • The connection between gut issues and behavioural challenges in autism is highly individualised. The heterogeneity of the autism spectrum means that each child may have a unique combination of genetic, environmental, and microbial factors influencing their gut-brain axis. In the Homeopathic holistic approach, we develop individualised treatment plans based on the child's specific needs and symptoms, which can lead to significant improvement in gut issues.


Understanding and addressing gut health issues in children with autism requires a multifaceted approach. By recognising the intricate connection between the gut and the brain, implementing individualised treatment plans and diets, we can bring about significant improvements in the gut health and consequently the behaviours of children with Autism.
