The gut / brain connection
The gut / brain connection has been receiving increasing levels of attention in medical research over the last decade. It’s now becoming clear that disruption in the gut can cause a range of not just physical but also psychological issues. These include depression, anxiety, brain fog, and ADD / ADHD. These two organ systems, once considered completely independent of each other, are now known to be tightly linked via the nervous system, hormones, and neurotransmitters. So much so that our gut is now often referred to as our ‘second brain’.
The microbiome is a neurotransmitter factory
The production and regulation of key neurotransmitters such as serotonin and dopamine is incredibly dependent on a balanced range of flora in our gut. For instance, more than 95% of the serotonin produced in our body comes from our gut bacteria, and 50% of our dopamine is produced in the gut. Disruptions to the balance of our microbiome through poor diet, antibiotic usage, and infection can all severely impact neurotransmitter production, having profound effects on our mental health.
Gut dysbiosis and nutrient deficiency
Another factor impacting psychological behaviour as it relates to our gut is nutrient malabsorption. We rely on both the structural integrity as well as the composition of our gut bacteria to facilitate the absorption of nutrients from the food we consume. When gut disruption occurs, this can result in quite severe nutrient deficiencies (even in the presence of a healthy diet). Without key nutrient components, we cannot produce adequate amounts of key neurotransmitters, thus resulting in many possible behavioural issues.
Detailed investigation is key
If any of my patients present with behavioural issues such as ADD or ADHD, and they also have symptoms of gut issues, ordering a comprehensive microbiome map test is always my first area of investigation. Identification of infection, poor microbial balance, leaky gut, and toxicity are all key areas that will need to be treated. Addressing these issues can have a profound effect on behavioural problems, so much so that I have taken to referring to our gut as our ‘primary brain’!
If you or any loved ones have been diagnosed with ADHD / ADD, or any other spectrum disorder such as Autism, and there are clear indicators of a dysfunctional gut, I strongly encourage you to seek further thorough investigation and analysis of the microbiome and to gently restore it’s healthy function. You could be amazed at the benefits it brings.
In wellness,
