How to Improve the Gut-Brain Connection: How It Works

Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder characterized by hyperactivity, impulsivity, and inattention. It affects people of all ages but is more prevalent in children. Digestive issues, on the other hand, encompass a wide range of conditions that affect the gastrointestinal tract. While these two conditions may seem unrelated, recent research has shown a connection between ADHD and digestive issues. This article will explore the gut-brain connection in ADHD and how it affects digestive health, as well as potential treatment options for finding relief.

The Gut-Brain Connection

The gut-brain connection is a term used to describe the bidirectional communication between the gut and the brain. The gastrointestinal tract is lined with a complex network of nerves known as the enteric nervous system (ENS), sometimes called the “second brain.” The ENS contains over 100 million nerve cells, which communicate with the brain through the vagus nerve.

The gut and the brain are also connected through the immune system, which sends signals between the gut and the brain. This connection is known as the gut-brain axis. The gut microbiome, the collection of microorganisms that live in the gut, also plays a crucial role in the gut-brain connection. The gut microbiome helps regulate the immune system, produce neurotransmitters, and maintain the integrity of the gut lining.

ADHD and Digestive Issues

Recent research has suggested that there is a connection between ADHD and digestive issues. Children with ADHD are more likely to experience constipation, abdominal pain, and bloating than children without ADHD. Adults with ADHD also report higher rates of gastrointestinal symptoms than those without ADHD.

One possible explanation for this connection is that the gut microbiome is altered in people with ADHD. Research has shown that children with ADHD have different gut bacteria than those without ADHD. These differences may affect the production of neurotransmitters in the gut, which can influence brain function and behavior.

Another possible explanation is that the immune system is dysregulated in people with ADHD. Studies have shown that children with ADHD have higher levels of inflammatory markers in their blood than those without ADHD. Inflammation can damage the gut lining, leading to digestive issues.

Finding Relief

If you or your child has ADHD and digestive issues, there are several things you can do to find relief. First, it’s essential to maintain a healthy diet. A fiber-rich diet, including fruits and vegetables, can help regulate the gut microbiome and reduce inflammation.

Probiotics and prebiotics are also beneficial for gut health. Probiotics are live bacteria that can improve the gut microbiome, while prebiotics are non-digestible fibers that feed the good bacteria in the gut. Both can be found in supplements or fermented foods like yogurt and kimchi.

Reducing stress is also important for gut health. Stress can cause inflammation and dysregulation of the immune system, exacerbating digestive issues. Mind-body practices like meditation, yoga, and deep breathing can help reduce stress and improve gut health.

Finally, it’s essential to work with a healthcare professional to develop a treatment plan that addresses both ADHD and digestive issues. Medications like stimulants can exacerbate digestive issues, so it’s important to find a medication that works for both conditions. Your healthcare provider may recommend other treatments like cognitive-behavioral therapy or dietary changes.


ADHD and digestive issues are two seemingly unrelated conditions that are connected through the gut-brain connection. Research has shown that the gut microbiome and immune systems are crucial in this connection. If you or your child has ADHD and digestive issues, maintaining a healthy diet, taking probiotics and prebiotics, reducing stress, and working with a healthcare professional can help you find relief.

It’s important to note that more research is needed to understand the gut-brain connection in ADHD and digestive issues fully. However, the growing body of evidence suggests that addressing gut health may be an important part of managing ADHD symptoms.
